Abstract

Light and wear resistant Al camshaft belt pulleys for engines were produced from standard Al powder mixtures with addition of hard particles. Pre‐screening tests of numerous inclusions showed 10 mass% ZrSiO~4~ to be the best choice. Full size belt pulleys were produced by pressing, sintering at optimized parameters, and sizing. Wear testing was carried out on pin‐disc testers and special belt pulley testbeds. Both dimensional and wear properties were found to be well comparable to those of conventional iron pulleys, with the exception of some attack on the belt by protruding particles after prolonged testing.
