る。SUMMARY OF THE INVENTION The present invention relates to a method for mass-producing sliding alloy bearings at low cost. Up to now, thermal spraying has been widely used as the simplest and cheapest coating method, but since it has low adhesion, it is hardly used as a sliding alloy bearing. Therefore, the present invention relates to a method for firmly adhering this thermal spray material to the base metal.

However, when treated by the remelting method or HIP, the adhesion is improved and becomes almost the same as the strength of the sprayed alloy. This is because the base metal and the sprayed alloy are diffusion bonded at high temperature.

The adhesion strength of these products was not so different from that of the former solder and the latter tin plating. Similar results were obtained with a copper alloy base metal. Further, remelting treatment was carried out with a laser as an alternative to the oxygen-acetylene flame, but the adhesion was as good as the former.
