Title:
VIBRATION TIP TOOL FOR ULTRASONIC HOMOGENIZERS
Document Type and Number:
WIPO Patent Application WO/2018/168288
Kind Code:
A1
Abstract:
[Problem] To provide a high-strength vibration tip tool for ultrasonic homogenizers that has excellent durability and erosion resistance using the SPS method. [Solution] A vibration tip tool for ultrasonic homogenizers wherein a metal base section, an intermediate layer section that is formed on one end face of the base section and that has a multilayer inclined composite structure in which a composition of the same metal material as the base section and at least one kind of ceramic material is inclined so that the former is reduced stepwise with respect to the latter, and a surface layer section that is at least one layer formed on the outermost face of the intermediate layer section and the primary component of which is the ceramic material that does not contain the metal material of the base section are integrally sintered while being pressurized using the spark plasma sintering method. Specifically, an intermediate layer made of titanium and zirconia and a surface layer section made of stabilized zirconia and alumina are integrally sintered to a titanium base section. Thereby, it is possible to obtain a high-strength, durable tip tool with excellent erosion resistance.
