: : We are experiencing difficulty with stellite coatings on our valve seat rings. Once they have been machined to size, the stellite cracks and flakes off. Is the problem caused by the process of applying the layer or is it there a reccommended method of machining?

: Hi Paul

: First I would check that the coatings are not being abused during machining.
: What stellite material are you using?
: How is the coating applied?
: What is the substrate material and condition?
: Regards Gordon
