摘要
The invention provides a method of preparing a wear-resistant coating layer comprising metal matrix composite and a coating layer prepared by using the same and more particularly, it provides a method of preparing a wear-resistant coating layer comprising metal matrix composite, which comprises the steps of providing a base material, preparing a mixture powder comprising a metal, alloy or mixture particle thereof having an average diameter of 50 to 100 um and a ceramic or mixture particle thereof having an average diameter of 25 to 50 um in a ratio of 1:1 to 3:1 by volume, injecting the mixture powder into a spray nozzle for coating, and coating the mixture powder on the surface of the base material by accelerating the mixture powder in the state of non-fusion at a rate of 300 to 1,200 m/s by the flow of transportation gas flowing in the nozzle and a coating layer prepared by using the same whereby the coating layer with high wear resistance and excellent resistance against fatigue crack on the surface of the base material without causing damages such as heat strain to the base material during the formation of the coating layer can be provided.
