Thin Dense Hard Chrome
Thin Dense Hard Chrome (TDC) is Metalife's Flagship product. A proprietary process established in 1964, TDC is bonded at a molecular level and has a 100% guaranteed bond. Our Thin Dense Hard Chrome plating overcomes conventional hard chrome weaknesses which can lead to immediate failure.

Conventional Hard Chrome Plating Weaknesses

  • Large cracks spread apart leading to rapid corrosion
  • Bath produces large amounts of Hydrogen gas leading to Hydrogen stress cracking, loss of ductility and load failure

Metalife Hard Chrome Advantages

  • Consistent uniform micro crack, excellent for holding lubrication and resisting corrosion
  • Eliminates the Hydrogen Phenomenon
  • Will not chip, crack, flake or peel

Metalife TDC will not affect a build-up of more than .00005" to .0003" under normal circumstances. The nodular structure of our Hard Chrome plating reduces the coefficient of friction substantially compared to other coatings.  Our TDC has a coefficient of friction rating of .12 to .16 depending on the application.

Quality comes first with Metalife and our Hard Chrome plating tank is strictly regulated.  Because of this our plating surface will be 99.4% pure as deposited.

Metalife Thin Dense Hard Chrome resists attack by almost all organic or inorganic compounds except sulphuric and hydrochloric (muratic) acids.  It shows no reaction in 48 hours with seawater, aerated seawater, or aerated rainwater.
Metalife's TDC conforms to Federal Plating Specs QQ-C320B CLASS 2,TYPE II.   The surface shall be completely uniform as shown in the microscopic picture at the right (click here to read the entire test report).


Remarkable Properties of Thin Dense Hard Chrome

Affects on Basic Metal Strength

The temperature of Metalife's processing solution is 136° F, however the process will withstand temperatures from -400° to 1800° F.  The tensile, yield and fatigue properties of the metal to be plated shall not be significantly affected by the process and there shall be no hydrogen embrittlement after processing.

Cost of Metalife Thin Dense Hard Chrome

The cost is governed by the condition, configuration and surface area of a part.  Prices may be determined by your drawing or by processing of a test part.

Metals for Treatment

Powder Metal production parts, all ferrous and non-ferrous metals that are commonly machine wrought or cast and steel, brass, copper, etc. can be processed.
