Laminar oxide in hvof coating
Hi everyone.
I am new to thermal spray process. Recently one of our hvof spray powder, amperit593, is showing obvious multiple layer in its coating. I presume this problem is called laminar oxide? I'll try to load the metalography pic when i get the opportunity.
The machine was just calibrated by oem just 2 months back, and we rechecked the coating recipe. Nothing was changed. We also changed multiple powder batches to try, showing the same results.
Does anyone have any opinion on this?
Thanks
