Titanium Finish Requirements
What finish treatments or coating would be required to give Titanium (grade 4) MIMed parts the corrosion resistance required to withstand Autoclave and chloride disinfectant wiping?Paul F. Lando

A coating per SAE spec AMS 2488 [affil. link to spec at Techstreet]D Type II.Jon Quirt

AMS2488, that is caustic anodize may do the trick, however, the fact that the parts are metal injection molded may rise to inherent porosity in the parts. This should be vacuum impregnated prior to finishing. Also, AMS 2488 is most often used as a base for dry film lubricant, DuPont Teflon, or other organic finish. Autoclaving and chlorine are tough environments to withstand, even for highly corrosion resistant titanium.
