Hi ,

Does anyone use Metco 350 NS with 6P-II for Bearing surface? What is the max thickness and do we spray boand coat for this powder?

Or suggest alternative powders for bearing (scuff) surface?

Hi ....
350NS is self-bonding with APS or 6PII, and reach a bond strength of about 40 MPa, if blasted with corindonum 15/24 grit, max service temperature is 340°c, if higher tend to oxidize the high molybdenum constituent, take care with spray-rate and spray distance, because are critical, and nozzle could powder build-up, and if lower spray-rate can decarburize excessively the coating
Best regards
