Anyone have any recommendations on a method to test different grades of tungsten carbide and how fast they oxidize over time? I'd like to test some cobalt bonded WC and some nickle bonded WC.

Here is a link to another forum and some discussion on the same topic. Does carbide rust ?

I have some old (5 years) tungsten carbide parts that are significantly darker than the new ones. How can I test new grades and see if they will do the same thing without waiting five years?
