Abstract

Six kinds of surface composite with different ingredients had been prepared on steel matrix by traditional cast processing. Impact wear properties of the prepared composites had also been studied by dynamic load abrasive wear testing machine with type of MLD-10. Results indicated the following four points. Firstly, composite layers on the casting bonded with matrix metallurgically. Secondly, hardness values of the composites increased firstly and then decreased gradually to the same value of the matrix in the direction perpendicular to the surface. Thirdly, the impact wear rate of the prepared composites decreased firstly and then increased with the increase of the high-carbon chromium iron content in reinforcements, reduced with the increase of the tungsten carbides content in reinforcements, enlarged firstly and then shrunk with the increased of impact energy. Finally, Wear mechanism of the prepared surface composites was mainly composed of plastic deformation and flaking off under the condition of impact wear.
