Date Jan. 14, 1988.Leakproof, adhesive, non-lamellar and pore-free antifriction coatings can be produced from essentially oxidation-sensitive dispersion alloys, with at least two metallic alloy components forming a miscibility gap in the solid state, by means of vacuum plasma-spraying with a practically homogeneous material distribution. Precipitation crystallites of alloy components are significantly below 5 mu m and fringe-crystal growth is definitely inhibited. By adding hard particles during the coating process further dispersion consolidation can be achieved. Such antifriction coatings improve longevity, corrosion resistance and emergency lubrication of sliding surfaces without reducing their running-in characteristics and their ability to bed in foreign matter. They can be deposited individually on to sliding bearing components or continuously on to supporting strips. |
