The anti-sticking coating is composed of tungsten disulfide, molybdenum disulfide, graphite and fluorinated polymer. In addition to the polymer material, other inorganic materials are used for the anti-adhesion coating in the implementation mode, so that the mechanical strength of the anti-adhesion coating can be improved, the service life of the anti-adhesion coating is prolonged, and the service life of a cutter bar is prolonged.
The anti-adhesion coating may comprise a ceramic material, and the ceramic material comprises at least one of: chromium carbide, tungsten carbide, titanium nitride, aluminum oxide, and chromium nitride. The ceramic material has larger mechanical strength, is not easy to damage, and can prolong the service life of the ultrasonic cutting tool.
The anti-adhesion coating may comprise a metal. Wherein the metal comprises at least one of the following: aluminum, stainless steel, and molybdenum. Because the metal has high mechanical strength and high ductility, the anti-adhesion coating made of the metal material can improve the toughness of the anti-adhesion coating, reduce the damage probability and prolong the service life of the cutter bar.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
