RE: ChromeOxide coating
Hello Ravi,
I have been developed Chrome carbide coating for replace to chrome plating.
In case of high temperature erosion, CrC coating is better than WC coating.
Because of NiCr alloy, CrC binder metal, is stronger at high temperature.
And NiCr alloy has excellent corrosion resistance.
However at room temp. or under 300?, WC has better wear resistance.
If you need corrosion resistance, could choose Co-Cr alloy for binder metal.
You expected just same level of Chrome plating's wear resistance, choose WC17Co.
It will bring you good result.
In my experience, CrC coating is more sensitive and difficult to WC coating.
Maybe the reason is difference of solidification between binder metal and carbide's thermal characteristics, especially heat capacity and thermal conductivity.
Cobalt has very wide adhesive temperature range, and good strength and low coating stress.
So cobalt is very easy coating material.
I wish your success.
Simon
