Potential relations of tribological characteristics of aluminum antifriction alloys with their compositions and mechanical properties were investigated. In this regard, the properties of eight aluminum alloys containing tin from 5.4% to 11% doped with lead, copper, silicon, zinc, magnesium, and titanium were studied. Mechanical properties such as hardness, strength, relative extension, and impact strength were analyzed. Within the tribological tests seizure load and wear of material were evaluated and secondary structures were studied afterwards. The absence of a definitive correlation between tribological behavior and mechanical properties was shown. It was determined that doping tin over 6% is excessive. The seizure load of the alloys increases with the magnesium content. Secondary structures of the alloys with higher wear rates contain one order less magnesium and tin.
研究了铝基减摩合金的摩擦学特性与其成分和力学性能之间的潜在关系。在此方面，研究了八种含锡量从5.4%至11%的铝合金，这些合金掺杂了铅、铜、硅、锌、镁和钛。分析了硬度、强度、相对延伸率和冲击强度等力学性能。在摩擦学试验中评估了材料的咬死载荷和磨损情况，随后研究了二次结构。结果表明摩擦学行为与力学性能之间不存在明确的相关性。确定锡掺杂超过6%是过量的。合金的咬死载荷随镁含量的增加而增加。磨损率较高的合金的二次结构中镁和锡的含量少一个数量级。
