Prevent of getting oval
I’m going to coat outer surface of several cylinders with the dimensions of φ190×230 & φ220×260 and wall thickness of 5.5 & 7mm respectively. The materials of these cylinders are stainless steel 420 & 316.
I really concern of getting the cylinders oval because of heating. So I really need your recommendation about this issue and your suggestions for rotating and traversing speed.
The coat composition is WC-10Co-4Cr and the coating method is HP-HVOF.
