Ultrasonic surgical knife and coating processing method thereof

The invention relates to an ultrasonic surgical scalpel and a coating processing method thereof, and a first material layer is processed on a blood coagulation cutting surface of the ultrasonic surgical scalpel, so that a single-layer low-friction-coefficient coating is coated on a metal base material. And the single-layer plating layer can be thinner, so that the product performance is better, and the service life of the product is prolonged. And the plating layer has better adhesive force than the coating, is not easy to fall off and meets the requirement of repeated use of the product. 本申请涉及一种超声外科手术刀及其镀层加工方法，本申请通过在超声外科手术刀的凝血切割面上加工第一材料层，实现金属基材上涂布单层低摩擦系数的镀层。单层镀层可以把镀层厚度做得更薄，产品性能更佳，从而提升产品使用寿命。镀层附着力比涂层更佳，更不容易脱落，满足产品多次使用需求。
