"Titanium Coloring"



2005

Q. Need assistance in achieving Dark Grey to Black Color for 6AL4V titanium using what ever "informal" process. I have heard of some companies being able to achieve this through anodizing the piece, but is there a thermal or less cost effective way to get a durable finish?
Any help would be appreciated.

A. You probably meant to say "more" rather than "less cost effective", David. The most "informal" process is paint of some type, but you haven't told us enough about the application to know if that has any merit. "Durable finish" probably means both wear resistant and corrosion resistant, right? But cost effectiveness almost always depends on size and shape and volume to be processed. Is this one single piece? How big is it? In short, what is the application? -- then we may be able to offer alternatives. Thanks.

A. Just paint it with 20% shellac solution(instead lacquer You can use any edible oil or fat,use it very sparingly),then heat it up to 400 °C (slowly). Cheap,simple and durable finish.

Good luck!

A. Like Ted said...not enough info given.
As for anodizing...I don't think it is possible to get a black on titanium. You can have titanium nitride coatings done but not actual hobby shop setup black anodizing. sometimes people will thermally treat niobium (heat to about 1500 and dip in water) to get beautiful hematite/black colors, or use aluminum and anodize with black dye(which will fade from UV exposure over years)and use these 2 materials in place of titanium, in the jewelry industry for example.
List more info and get more accurate help.

A. You can do black on titanium, but it is not common or easy. I believe letter 30989 addresses it.
