Abstract
In this paper we performed comparative studies of the tribological properties of the AlSi15Cu3 antifriction silumin and BrOTsS5-5-5, BrOF10-1, and BrAZh9-4 bronzes during friction in the I-20A lubricant environment in a wide range of sliding speeds and test pressures. It has been shown that no accumulation of defects occurs in the crystal lattice in its surface layers during the friction of an aluminum alloy. This is associated with the low recrystallization temperature of the aluminum matrix phase of the alloy. We conclude that AlSi15Cu3 antifriction silumin is a promising material for replacing expensive antifriction bronzes in highly loaded friction units.
