Powders of Al-Sn-Cu system for plasma anti-friction coatings

摘要

The technology for production of Al-Sn-Cu alloy(Al-5.8-6.2 Sn-0.5-1.2 Cu and Al-18-22 Sn –0.5-1.2 Cu) isdeveloped. The technology for gas thermal powder spraying andproperties of anti-friction coatings are studied. Friction ratioconstituted 0.02-0.04 for sprayed coatings. Grip load made 5,000-6,000 MPa and number of cycles before destruction is 7-12 mln.
