Ceramic coating on Polyurethane

Posted by Chris on March 16, 2004 at 18:00:53:

Dear Sir,

Is ceramic coating on polyurethane possible ?

The component is made of polyurethane on which slurry, iron ore and coal circulate at ambient temprature. The material has a tendency to adverse against the polyurethane surface. PH value is normal. The rotating speed is a min of 2 meters per cubic hour with a maximum of 10. We would like to know -

What kind of ceramic can be used ?

What is the maximum thickness that can be built up ?

Can 9 Mohr scale hardness be acheived with ceramics ?

We would also like to know if tungesten carbide can be sprayed on polyurethane surface.

If yes what are the pre cautions that need to be taken.

Are there any other options ?

Thank you in advance.
