Title:
WEAR RESISTANT FILM, ITS FORMATION AND STARTING MATERIAL THEREFOR
Document Type and Number:
Japanese Patent JPS6314853
Kind Code:
A
Abstract:
PURPOSE: To easily obtain a film having superior wear resistance and high oil retentivity by thermally spraying starting material consisting of Cr2O3 and Cr3C2 in a specified ratio on the surface of a member to form a film.
CONSTITUTION: Starting material contg. 95W30pts.wt. Cr2O3 of about 5W63μm particle size and 5W70pts.wt. Cr3C2 of about 5W63μm particle size is thermally sprayed on the surface of a member to form a film. The film may further contain Mo, Ni, Co, and Ni-Cr alloy or the like as required. The surface of the film may be projected with laser beams so as to accelerate melting. When the resulting member is used as a sliding member or the like using a lubricant, the durability is considerably improved.
