METHOD FOR MANUFACTURING METAL BASE MATERIAL HAVING GROUND LAYER FOR DOUBLE LAYER BEARING, METHOD FOR MANUFACTURING DOUBLE LAYER BEARING, METAL BASE MATERIAL HAVING GROUND LAYER FOR DOUBLE LAYER BEARING, AND DOUBLE LAYER BEARING

摘要

PROBLEM TO BE SOLVED: To provide: a method for manufacturing a metal base material having a ground layer for double layer bearings, advantageous when improving durability in a corrosive environment; a method for manufacturing the double layer bearing; and the double layer bearing.SOLUTION: A double layer bearing 10E comprises a metal base material 12, a ground layer 14 provided on the metal base materials 12 and a resin layer 16 provided on the ground layer 14. The metal base material is a stainless steel plate 12. The ground layer 14 is formed by piling a stainless steel powder 20 through a brazing filler metal for joining on the surface of the stainless steel plate 12. The ground layer 14 is formed by spraying a mixture 22 formed by mixing the stainless steel powder 20 with the brazing filler metal for joining on the stainless steel plate 12, heating the mixture in a non-oxidative atmosphere to melt the brazing filler metal for joining and slowly cooling the brazing filler metal for joining after the heating.
