る。(Prior art) Conventionally, hard chrome plating with a satin finish was applied to the surface of a metal material as a splicing member for synthetic fiber yarns that required abrasion resistance and low 1 m resistance characteristics, and the surface hardness was HV7.
A welding member having a finely uneven surface of 00 to 1000 was frequently used. In addition, as the 1IIIi yarn becomes more sophisticated, the yarn count becomes finer, and the speed of nano-nm textile machines increases, a harder joining member is required.

いた。In addition, methods for roughening the surface of ceramic materials include the shot blasting method, in which fine grained abrasives are sprayed onto the surface of the ceramic material, and the method of roughening the surface of the ceramic material to create an uneven surface. There is a method of firing at a high temperature and crystallizing the main raw material as it cools, forming an uneven surface with continuous crystals on the surface of the ceramic material, but in the former case, the surface of the ceramic material is physically crushed. In the latter case, the crystal structure changes depending on the raw material composition, firing temperature conditions, etc., so it is difficult to maintain a uniform and moderate roundness. There is a problem in that it is extremely difficult to generate an uneven surface, making it difficult to produce a lamic splicing member that satisfies the required characteristics.

The wear state of the surface layer in region M is clearly shown, whereas the surface roughness tilate of sample A shows the irregularity of the roughness curve in the friction region M and the roughness curve in the non-friction region. The unevenness is almost uniform, which clearly shows that Sample A has extremely excellent wear resistance.
