Steel used in aggressive environments with corrosion coupled with high wear have traditionally used electroplated engineered hard chrome (EHC) for surface protection. While other electroplated metals provide good corrosion resistance (like cadmium Cd and Zinc Nickel ZnNi), they are removed quickly under wear conditions, leaving the steel exposed to corrosion. In reent years, there has been a push to replace toxic hard chrome plating to improve worker health and safety.
Integran Technologies has developed an electroplated nanocrystalline Cobalt, called Nanovate CoP (also referred to as nCoP, or Nanovate CR), that is a cost effective and higher performance, drop-in replacement for hard chrome plating.
The process has been proven stable thourgh industrial application of millions of amp hours, and there are industrial products with the material in the field since 2008. The process is covered by the US DoD Mil-Spec "MIL-DTL-32502-COATING, COBALT-PHOSPHORUS ALLOY, NANOCRYSTALLINE - (ELECTRODEPOSITED)". An SAE - AMS Specification for the process is in the approval process (Document B13AA - "Nanocrystalline Cobalt-Phosphorus Electroplating") as of November 2013.
Integran licenses the technology to interested parties (currently deployed to Navair, Pratt and Whitney, and Enduro Industries), and offers low to medium volume production and application engineering through it's facilities in Toronto, Canada. The material is particularly well suited for sliding wear applications (hydraulics, pneumatics) and high chloride corrosion environments (salt spray, muriatic acid wash-downs etc.)
