Thin Dense Chrome Plating

Thin Dense Chrome (TDC) plating is Metalife's Flagship product. A proprietary process established in 1964, TDC is bonded at a molecular level and has a 100% guaranteed bond. Quality comes first with Metalife and our Thin Dense Chrome plating tank is strictly regulated.  Because of this our plating surface will be 99.4% pure as deposited. Our Thin Dense Chrome plating overcomes conventional chrome weaknesses which can lead to immediate failure.

Conventional 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 Thin Dense Chrome Plating Advantages

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

Metalife Thin Dense Chrome plating 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.

The surface of our Thin Dense Chrome Plating shall be completely uniform as shown in the microscopic picture at the right (click here to read the entire test report).
