Titanium coating question
My uncle works for a company that does different coatings for metals. Mostly medical equipment, precision tools, etc. He said he can do a titanium nitrate coating on my forks for free, but he needs to know a few things about the forks:
1. What type of metal they are made from (steel, alum, alloy, etc.)
2. If they were heat treated during manufacturing, and if so, to what temp.
3. What temp. can they be heated to before damage occurs.
If anyone knows any of these answers or can point me in the right direction, I would greatly appreciate it.
