A new surface alloying technology - arc glow iontophoresis metal technology and its basic principle and experimental device are introduced. The carbon steel samples with arc glow plasma treatment were enumerated. The microstructure, alloy composition and phase composition of the coating were analyzed and discussed. The diffusion coefficient of titanium in γ-Fe was calculated by mathematical method. The relationship between diffusion coefficient and alloy element concentration is discussed.
