: Who can give me some idea about how to grind and polish the Al2O3+TiO2 plasma sprayed ceramic coating in concave surface? workingpiece was yarn guide wheel.
: they were without precise dimension requirement. But we hope to improve the efficiency in grinding.
: I appreciate if I can get reply.

Hi Jian

What grinding and polishing methods have you tried and what finish or texture do you require?
Normally, diamond grinding initially with 150 grit wheels are recommended, but with your application it may be worth considering a brushing method particularly if dimensional or flatness are not important factors.
