Hardlayer on Titanium


2001

We have a cryogenic application (4 K) of a titanium shaft (TiAlVa64) making oscillating movements (about 2.5 degrees) in a AISI 316 sleeve with a pressure load of 73 N/mm2 without any lubrication except liquid Helium. Although there is a reasonable hardness difference, I wonder if a hardlayer on the titanium shaft is needed to prevent pitting or other wear. A hardchrome layer is impossible to get to the surface due to the TiO2-skin.

Your help would be appreciated very much.

Aren't the metals (and alloys) already extremely hard and brittle at cryo temperatures? You are nearing absolute zero. A hard coating may not be of use.
