Vibration tip tool for ultrasonic homogenizer

摘要

PROBLEM TO BE SOLVED: To provide a vibrating tip tool for an ultrasonic homogenizer using the SPS method, which is high in strength and excellent in durability and erosion resistance. SOLUTION: The vibrating tip tool for an ultrasonic homogenizer of the present invention is formed of a metal base portion and one end surface thereof, the same metal material as the base portion and at least one ceramic material. An intermediate layer portion having a gradient composition structure of a plurality of layers, the composition of which is inclined so that the former gradually decreases with respect to the latter, and at least one layer is formed on the outermost surface of the intermediate layer portion, and the base member portion And a surface layer mainly containing the above-mentioned ceramic material which does not contain a metal material, and integrally sintered while being pressurized by a discharge plasma sintering method. In particular, by integrating the intermediate layer composed of titanium and zirconia and the surface layer composed of stabilized zirconia and alumina on a titanium base material by sintering and integrating, high strength, high toughness, and excellent erosion resistance It will be.
