coating problems on spheres
Hello colleaguesShy,

We have problems to coating some spheres (Co-Cr-Mo material) with METCO 131VF (alumina-titania powder), we need build a system where we mount the spheres and then apply the coating, but we dont know:

The rotational frecuency RPM to sphere and traverse speed which the robot should be moved? because to sphere diameters is so small (0.75") and we need apply 200 micrometers thick.

How affect exposition time plasma on sphere?

Somebody know how much material remove the grid blasting process,if i use a alumina mesh 40?

i never saw a problem like this, i see in others thread where talk about coating on cylindrical forms but never on spheres, and with that diameter (very small).

I see in other thread with the name " WC-Co16 coating problem enquiry" the administrator suggest 5 points or steps for solution the problem with rotating pieces (cylindrical only) but i wonder how can apply that method or steps on my problem.

This is the link of the thread mentioned above:

i am open for all suggestions or comments.

my regards from mexico friends.Big Grin
