Study on non-stoichiometric titanium monoxide resistance to discoloration and corrosion resistance

titanium monoxide;  imitation gold materials;  Anti-discoloration performance;  Corrosion resistance

The discoloration and corrosion resistance of non-stoichiometric titanium monoxide as a gold-imitation material may be exposed to different environments was studied, and compared with the existing gold-imitation materials. The results show that titanium monoxide has excellent anti-discoloration ability in outdoor atmosphere, household atmosphere, soil, artificial sweat, 18KAu corrosive, sodium chloride solution and concentrated ammonia, and its chemical stability and anti-discoloration performance are significantly better than TiN-based cermet gold-like materials and gold-like copper. In dilute sulfuric acid and dilute hydrochloric acid, corrosion is slow and does not change color.
