How do I coat copper with titanium?


I read about a copper bar coated with titanium. Does anyone know how it can be done?

Denir Paganini Nascimento


It is best to buy it from somebody in the business. It amounts to having a Ti tube with very tight tolerances and forcing a copper bar of a precise size into it.

This can partially be accomplished by heating the tube and freezing the copper in either liquid nitrogen or a dry ice and methyl alcohol bath. You bring the copper out and rapidly force it into the tube. If you are not fast, you have a copper bar stuck partway into the tube. I guess you could always pour molten copper into the Ti tube if you have that capability.

There are all sorts of ways to deposit titanium on copper bars -- HVOF, PVD, et al. What is the application?
