Beschreibung
Zusammenfassung:	The invention relates to a coating material and application thereof in the field of medical instruments. According to the invention, TiN, SiO2, CeO2 and WS2 are taken as powder raw materials, the composite coating is prepared on the surface of a medical stainless steel matrix through laser cladding by adopting a synchronous powder feeding method, and the composite coating prepared by taking TiN as a basic material and matching with auxiliary raw materials such as SiO2, CeO2 and WS2 has excellent corrosion resistance and wear resistance. The composite coating material can be applied to medical instruments such as tissue forceps so as to prolong the service life of the medical instruments. 本发明涉及一种涂层材料及其在医疗器械领域的应用。本发明以TiN、SiO2、CeO2和WS2为粉末原料，采用同步送粉法激光熔覆在医用不锈钢基体表面制备复合涂层，以TiN为基础材料，搭配SiO2、CeO2、WS2等辅助原料制备得到的复合涂层具有优异的耐腐蚀性能和耐磨性能。该复合涂层材料可以应用于组织钳等医用器械以延长其使用寿命。
