Vapor deposition of titanium on aluminum

I am looking forward for your suggestion regarding the vapor deposition of titanium on aluminium and/or steel. Can any one provide details of this technology? I wanted only a few microns of titanium coating, which would be friction less and highly corrosive resistant. I also would like to know whether this technology can be a commercially viable?

Thanks in advance,

Dear Dr. Bulusu Sreenivas,

First for your question, Yes. Titanium can be deposited on Aluminium and or Steel. It can be carried by Using Physical Vapour Deposition. You can get a coating thickness of around 3-4 Microns radially. I like to know your exact purpose of coating Titanium. Is it only for corrosion resistance and friction less? This titanium coating is commercially viable.

It is possible to vacuum deposit titanium on aluminum, but why would you want to? Titanium is neither low friction nor wear resistant. It is one of the toughest materials to machine because it galls so readily.

Titanium nitride is a good wear resistant coating, though not very low friction. It is extremely hard, with a very high modulus of elasticity. It is not a particularly good coating for aluminum for those reasons -- a thin hard veneer on a soft substrate does not lend itself to particularly good wear resistance.

Why not chrome plate it?
