HV hardness The plasma spraying can be up to


Posted by Jian Pu on May 03, 2003 at 06:58:23:

Hi,

I sprayed the Al2O3+13TiO2 at HV hardness 750 to 850 most of time, few cases up to HV920, by plasma coating. But measure the sample from Germany it average HV1000, how they get that level? if they use different method or by other equipment?

By investigating, most of info. are HV850.

Thanks.
