Title:
SLIDING MATERIAL AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3755932
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain good joinability and to simplify the producing process by sinter-joining the surface of an ferrous base metal with a copper base sintering sliding material contg. titanium.
SOLUTION: In this producing method, a green compact composed of lead- bronze powder is placed on a steel previously worked into a prescribed shape, which is passed through the inside of a reducing atmosphere, by which joining is executed together with sintering. At this time, titanmum as a sintering assistant is added to the lead-bronze powder for generating sufficient liq. phases in the joining and also preventing the coarsening of lead. In this way, the generation of a large amt. of liq. phases from the alloy components other than lead in the lead-bronze alloy can be suppressed, furthermore, the wettability of the lead-bronze alloy with the ferrous base metal can be improved, and moreover, the growth of the lead grains can be suppressed. In this way, the sliding material good in both of the sintering phases and joining state can be obtd. Moreover, since a plating stage is needless in the producing process, the process can be simplified.
