Abstract: By using TIG welding, ferrite based composite coating reinforced with TiC has been synthesized by preplaced alloy powder which contains Ti and C on the surface of conventional carbon steel.Results show that in situ TiC particles were prepared in the coating.The microstructure of the coating was mainly composed of ferrite, retained austenite, TiC particles and carbide.The surface hardness of the coating is higher than 55 HRC and presents gradient distribution nearer to the surface of the coating.The wear-resisting test indicated that the friction coefficient of the coating is varied acutely.Blocking effect of TiC particles leads to excellent wearing resistance.The coating has a excellent wear-resisting property.The result of wear-resisting test shows that the wear-resisting volume of the coating is less than that of the base metal by 15-20 times.
