| Techmetals can formulate
specialized coatings to overcome your wear, corrosion, release, and other
challenges. Our experienced R&D department can custom make special alloys or
dual deposits to fill multiple needs. In addition, we can add sub-micron
diamond-like particles for added hardness and wear, or PTFE particles for
release and lubricity. If your problem cannot be solved with a conventional
coating, let us engineer a coating for you. Some of our coatings are listed
below.
|
Armatech
|
Becomes a part of the metal itself and will not chip, peel, crack, or flake
even when subjected to standard bend tests. Armatech will not affect dimensions
by more than .0002 per surface. It is recommended as a final process eliminating
additional grinding and finishing operations. Designed for sliding in metal to
metal applications, with excellent ability to retain lubricants.
|
|
Cromvet
|
A Tin Cobalt Alloy that is used as a replacement for decorative chrome. It has a
similar appearance to chrome without the environmental complications. This
coating also proves beneficial from an engineering standpoint because of its
lubricity. It is often used over other coatings.
|
|
Diamonize |
It is a complex metal matrix containing diamond particles. |
|
E-Krome
|
A uniform electroless process, 60-65 Rockwell as plated. We think of it as
electroless chrome. It has the color, hardness, and low coefficient of friction
similar to chrome. E-Krome also has the ability to cover uniformly over complex
geometries without the use of electricity, thieves, robbers, or shields. This
coating helps to alleviate environmental concerns around the use of hexvalent
chromium.
|
|
OptaKoat
|
This amorphous, nickel, high phosphorus(~14%) coating is an excellent coating
for diamond turning applications. It can outperform electroless nickel
phosphorus deposits in the areas of low tool wear and achievable finishes. Test
have shown that after using conventional optical lapping techniques, the surface
roughness was reduced to 2-3 angstroms. This is a finer surface roughness than
elecrtoless nickel phosphorus can offer. Optakoat can be plated to a thickness
of 0.080" or higher, and it has a lower volume void, which lead to fewer defects
in coating.
|
|
Optical Grade Electroless
Nickel
|
"Optical Grade Electroless Nickel" is a high phosphorous, high build deposit, which is formulated specifically for the optics industry. This
coating is perfectly uniform and can be plated to thickness exceeding 0.015” pit free.
This optic grade EN uses the best chemistries in a controlled atmosphere. It is
highly suitable for single point diamond turning. |
|
OxyTech
|
More than just hard coat anodize. This rigid process delivers a Type III anodize
finish that is not only more consistent, it has been proven to outwear standard
hard coat anodize finishes.
|
|
OxyLube
|
The same superior hard coat anodize finish as OxyTech, with the added lubricity.
We have taken sub-micron particles of PTFE and impregnated them into the coating
for added wear and lubricity.
|
|
Techniloy
|
A hybrid EN deposit coating developed to compete with electroless nickel and other alloys. This deposit has superior corrosion resistance and can usually offer a cost savings.
|
|
Triplex Chrome
|
This process improves the corrosion resistance and surface finish of the best
chrome formulations. For best results, this deposit is usually plated to finish,
size, with a maximum thickness of .005.
|
| UltraKoat |
An electroless nickel co-deposit with sub-micron particles of a
diamond-like material. This deposit has a very low coefficient of
friction and can be used in applications over 500 degrees F, where
Teflon starts to decompose. The diamond-like particles and low
coefficient of friction give this coating the ability to perform
well in sliding, wear, and abrasive applications. Not recommended
for fluid wear. |
| TM 103 |
Electroless nickel plating at its best. This process has a high
phosphorus content, 10%+. It is free of heavy metal contaminants and
is relatively pore and crack free. It has a uniform deposit, which
actually encapsulates the part and a hardness of 47-52 Rockwell as
plated, heat treatable up to 65-70 Rockwell. There is superior
corrosion resistance to that of standard electroless nickel. One mil
thick coating has shown no rust after 1,000 hours in a salt spray
test. This coating can obviously be used where corrosion resistance
is of great importance. It complies with FDA and USDA regulations
for use on food handling equipment. |
| TM 105 |
A unique hard chrome that is brighter, harder, and more corrosion
resistant than standard hard chrome plating. This deposit can be
plated up to 71 Rockwell C compared to standard chrome, which ranges
from 64 to 67 Rockwell C. Its brightness and low coefficient of
friction make it ideal for molds and metal cutting tools. TM 105 is
best known for its release, excellent wear, and anti seizure
characteristics. |
| TM 109 |
An electrolytic nickel deposit of the purest nickel providing a
soft ductile coating of 20 Rockwell hardness. It has outstanding
corrosion resistance, solder ability, magnetic characteristics, and
resists oxidation at high temperatures. Coating thickness up to
.250" can be obtained. Techmetals can handle small or large parts
with a 5-ton capacity and tanks up to 10-feet in length. Engineering
applications in the nuclear, textile, printing, petroleum, and
electronics industries are widely accepted. TM 109 is ideal when a
pure, stress free, machinable, and corrosion resistant deposit is
required. |
| TM 109-H |
The hard version of 109. A hard chrome substitute for salvage of
mis-machined or worn parts. This deposit has the advantage of being
MACHINEABLE at 35 to 40 Rockwell C. In addition, it is excellent for
heavy build-up. It is used on worn shafts that require heavy
build-up. It is also suitable to salvage flats and inside diameters.
|
| TM 111 |
This is an electroless nickel plating with a hard chrome overlay.
It is used for applications that demand the MAXIMUM corrosion
resistance of electroless nickel, while maintaining the hardness and
superior wear of chrome. This innovative deposit is well accepted in
the printing, chemical, and aircraft industries.
|
| TM 117C |
A composite material obtained by co-depositing a high phosphorus,
(10%+) electroless nickel with PTFE particles. The PTFE particles
are evenly dispersed throughout the metal matrix, occupying 15 to
25% by volume. The PTFE particles are protected from abrasion by the
metal matrix. As wear occurs, PTFE particles are continuously
brought to the surface, which insures dry lubrication throughout the
surface life of the plated part. It has excellent resistance to
adhesive wear, with uniform and accurate coating thicknesses. This
coating can be used on mold surfaces, food process equipment,
computer components, aerospace applications, and other applications
that require dry lubrication. |
| TM 117P |
A high phosphorus (10%+) electroless nickel, hardened to 64 to 70
Rockwell C, and infused with PTFE. This coating provides a very
accurate, dry lubricated hard surface. It has excellent resistance
to adhesive wear, with great release properties. TM 117P is used on
mold surfaces for both plastic and rubber molding applications, food
process equipment, computer components, aerospace applications, and
more. |
| TM 119 |
This specially engineered dense hard chrome is deposited so that
it can be impregnated with (polytetrafluroethylene) PTFE. The PTFE
enhances the release, wear, and corrosion properties of chrome. It
is used where the chrome deposit needs additional release and a low
coefficient of friction, such as metal forming tooling and molds. |
| TM 121 |
A crack-free chromium deposit. This deposit has good corrosion
resistance. Standard hard chrome has approximately 200 to 400 cracks
per linear inch allowing corrosive material through to attack the
base metal. Crack-free chrome is a barrier coating. This deposit is
somewhat softer and more ductile than standard hard chrome. As
deposited, it is matte gray, but may be polished to a bright finish.
It is often used in direct contact with molten glass. |
| TM 129 |
A low phosphorus, high hardness, electroless nickel that is 55 to
60 Rockwell C as plated. This uniform deposit is used on aluminum
and "even" tempered alloys for hardness. Its corrosion resistance is
outstanding in alkaline atmospheres. This coating has found great
acceptance in the glass industry on molds, plungers, and other
tooling. |
| TM 133
|
A boron, electroless nickel with low internal stress. This coating is uniform
and has excellent wear resistance. In addition, it has good solder ability, weld
ability, and excellent wear resistance at a hardness of 63-65 Rockwell C as
plated and heat treatable to 1200-1300 KNH 100, approximately 80 Rockwell C. Our
Boron Nickel has a much lower coefficient of friction than chrome. This deposit
is often used to replace hard chrome, carbide, and even titanium nitride.

|
X-Calibur |
This coating goes on perfectly uniform and can be engineered to increase wear resistance
or abrasion. It is a tungsten alloy that looks like chrome. It has superior corrosion
resistance to chrome. Salt spray tests show X-Calibur outperforms hardchrome 10
times longer with a .001 or .25 micron deposit. Wear tests show this coating outperforms
hard chrome 17 times in non-lubricated test and 6 times with lubrication. |
