SWASH PLATE OF SWASH PLATE TYPE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To improve seizure resistance and abrasion resistance by covering aluminum alloy including a prescribed quantity of Si and having granular Si dispersed therein, and a thermal spraying layer including a dispersed phase composed of carbonaceous material such as graphite or MoS2 in a matrix composed of the aluminum alloy over a substrate. SOLUTION: In forming a swash plate 2 having high Si - aluminum alloy superior in sliding characteristics set to a surface sliding layer, aluminum alloy including Si 2-60 wt.% and having granular Si dispersed therein and a thermal spraying layer formed by including at least one kind of a dispersed phase out of a group composed of a graphite type, amorphous carbon, carbon having an intermediate crystallized state between them, or MoS2 in a matrix composed of aluminum alloy cover over the swash plate 2. In this case, Al-Si-Sn based alloy adding Sn 0.1-30 wt.% may be used for the matrix. This constitution can provide seizure resistance and abrasion resistance superior to a lead bronze thermal spraying layer.
