Nanotribology investigations of composites based on Za-27 alloy reinforced by Al2O3 particles

Abstract

Results of tribological investigations of composites based on ZA-27 alloy, reinforced with Al2O3 particles of 250 μm size, with three different mass shares percentage as follows: 3 %, 5 % and 10 %, are presented in this paper. Tribological investigations are realised on nanotribometer with linear reciprocating module setup. Four levels of normal contact loads are varied during testing (10 mN, 50 mN, 100 mN and 120 mN) and three levels of speed (10 mm/s, 20 mm/s and 30 mm/s), with no lubrication.
