With a total of three patents to his name, Dong's work focuses on enhancing the properties of these materials through innovative methods.
Latest Patents
Dong's latest patents include a method of case hardening an article formed of titanium, zirconium, or an alloy of titanium and/or zirconium. This method involves heat-treating the article in an oxidizing atmosphere at temperatures ranging from 700 to 1000 °C to form an oxide layer. Subsequently, the article is further heat-treated in a vacuum or neutral atmosphere at the same temperature range to allow oxygen from the oxide layer to diffuse into the article. Another significant patent addresses the surface oxidation of titanium or titanium alloy articles. This process improves the tribological behavior of the articles by gaseous oxidation at temperatures between 500 to 725 °C for a duration of 0.5 to 100 hours. The result is an adherent surface compound layer containing at least 50% by weight of titanium oxides with a rutile structure.
