Abstract Scope |
Plasma Surface Metallurgy is newly emerging advanced field in materials science and engineering. From the plasma nitriding for metal surface treatment developed in 1930s, to the plasma surface alloying for metal surface metallurgical modification with double glow discharge plasma process (Xu-tec process) been developing since 1980s, the plasma surface metallurgy has been well established to meet industrial demand for proper surface modification (surface metallurgy) for its physical, chemical, or mechanical property changes required for many specific applications. Industrial applications of this technology have generated huge economic profits and social benefits with environment-friendly and resource-saving. This presentation is to introduce our engineering work and in-depth understanding on Plasma Surface Metallurgy by the double glow plasma surface alloying technology. Several application examples will be shown, such as surface alloying on iron and steel, Titanium and alloys, and intermetallic compounds, for enhancing surface properties of wear-, corrosion- and flame- resistance. |
