Wear Conditions for a Composite Material Based on an AO20-1 Antifriction Alloy Reinforced with Titanium Particles
摘要
Abstract
Composite material specimens are fabricated by reaction casting by mixing titanium particles to form Al3Ti intermetallic phases. Dry sliding friction tests are carried out according to the scheme of end loading of a fixed sleeve (grade 45 steel) on a rotating disk (specimen) at sliding speeds of 0.25–0.75 m/s and loads of 0.5–3.5 MPa. Wear intensity maps, which determine friction regimes during a test, are constructed. The boundaries and conditions for changing the friction regimes are shown.
