WC/Co/Cr on Stainless steel 420 coating
Hello,

Does any one have experience with spraying WC/Co/Cr coating by HVOF on grinded stainless steel 420 wire coating. I have some doubts about good adhesion.

Regards

Hi Arturas
It depend of what do you mean with good adhesion, it isn't a measure of adhesion, of course you could have some MPa lower than Standard steel, but the adhesion depend on the sand blasting operation, parameters, etc...
Best regards

RE: WC/Co/Cr on Stainless steel 420 coating
A well applied SS 420 cating with an initial bond coat can always be blasted and HVOF coated upon, with no issues with bonding of the HVOF layer with the Metcoloy II coating

However - it must be noted that any coating is as good as the weakest bond strength - and in this case, the performance shall not be determined with the bond strength of the Carbide and 420 layer; but the substrate and the 420 layer

This must be kept in mind prior to following this coating system...
