Sleeve Coating
Dear SEF members,

We have a part of pomp sleeve.

Working conditions:

Pure Water 140 C
Abrasive materials: Plastic o-rings
The Ceramics coating was applied but efficiency could be obtained.

We are planing to coat CrC/NiCr with HVOF. But do you have Any other suggestions?

Thanks.

RE: Sleeve Coating
ARC Spray ? what about a wire equivelant to Tafa 95 MXC

Hardens under abrasion to around 75Rc ? Used on boiler tubes etc in power stations ?
