This article introduced the technology of glow-discharge surface alloying with arc sources.Titanizingwasachieved on the surface of carbon steel with different carbon content by using this technology. The distribution of elements in diffusion layer were determined by usingX-Ray diffraction apparatus andTEM.The phases and their distribution in diffusion layer were studied. The phases in the Titanizing layer of mild- steel were ferritα),-FeTi and γ-TiC. When the sample hashigh carbon content(0. 6wt.%,1.2w.%), the phases in Titanizing layer was mainly γ-TiC.
