Hard Chrome Plating

Hard chrome is one of the most reliable and widely used metal plating processes in the industry. Typically used to help resistance to abrasion and corrosion, industrial chrome also helps improve a part’s wear.

Chrome plating is generally used in offering deposit thicknesses of >0.1 mil, and up to 20 mils or more.

Techmetals application of hard chrome provides moderate corrosion and oxidation protection for the coated substrate. It is especially effective when applied to the cavities of molds, dies, tools and other components where abrasive resins are processed.

Consider Techmetals for chrome repair or salvaging older parts, molding dies, aircraft engine parts and more.

Benefits of Hard Chrome:

  • Wear Resistance
  • Part Repair
  • Corrosion Protection
  • Non magnetic
  • Easily applied over any finish,
    mimicking the base substrate

Techmetals Engineered Hard Chrome Finishes


armatechBecomes 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 wear in metal to metal applications, with excellent ability to retain lubricants.


tm105A 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.


tm111TM 111 Electroless Nickel (EN) with a Hard Chrome deposit overlay. The base of the EN provides a uniform corrosion resistant barrier coating.

The EN Hard Chrome overlay provides a hard, wear resistant surface. This deposit can be plated on all ferrous and most non-ferrous metals.


tm119This 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 most often used where the chrome deposit needs additional release and a low coefficient of friction — such as metal forming, tooling and molds.


TM121 is a crack-free, chromium deposit offering a good corrosion resistance. Standard hard chrome has approximately 200 to 400 cracks per linear inch, allowing corrosive material through to attack the base metal.

TM121 crack-free chrome is a barrier coating — depositing somewhat in a softer and more ductile manner 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.


Diamoforce is one of Techmetals’ latest chrome alloy plating technologies. This coating has extreme hardness and an amazing wear resistance.

This alloy provides a slick surface that reduces the coefficient of friction. Diamoforce also reduces galling and improves lubricity.

The deposit has a unique nodular structure, which provides for it’s excellent wear characteristics. A great non-stick solution that helps resist corrosion.

Splatter Guard

Splatter Guard is one of Techmetals’ latest advances in coating technology. This hybrid version of TM 107 is a very hard coating that provides exceptional wear, corrosion resistance and release.

One distinct characteristic of Splatter Guard is the deposit conforms to the base metal. Thickness is typically .0001”-.001”, although it may be varied slightly outside of these parameters to meet your needs.

Splatter Guard, as deposited, has a coating hardness of 66-70 Rockwell C. Splatter Guard exhibits a low coefficient of friction and anti-galling properties. In most applications, it will last 2 to 10 times longer than other parts or processes. It will not fill in or cover up blemishes or scratches.


This process is precisely controlled by our lab staff and engineering team. TM-Rx is a medical-grade, chromium coating designed to prevent wear, galling and corrosion. Parts and instruments coated with this material are designed to work and look like new after 1,000 cycles in an autoclave.

TM-Rx meets or exceeds ISO 10993-1 Certification, as well as the principles governing the biological evaluation
of medical devices. Certified report numbers: 331553, 331617, 331621 and 331555.
