历来,作为内燃机滑动轴承的材料主要是锡基和铅基巴氏合金、磷青铜、锡青铜、铅青铜合金等。国外近年来在改善和发展新的轴承合金材料方面做了大量的试验研究工作,主要对有发展前途的铝基合金轴承材料做了研究和改进。现介绍如下: 一、铝硅镉系改良合金 作为内燃机滑动轴承的合金层,其使用性能优于众所周知的磷青铜、锡青铜、铅青铜、巴氏合金、铝锡系、铝硅系及铝硅镉系合金。 1.铝硅镉锆合金。主要化学成分:Si2
Historically, as the internal combustion engine sliding bearing materials are mainly tin and lead-based Babbitt, phosphor bronze, tin bronze, lead bronze alloy. Abroad in recent years in the improvement and development of new bearing alloy material has done a lot of experimental research, mainly on the development of aluminum alloy bearing materials have been studied and improved. Now introduced as follows: First, the Al-Si-Cd-based alloy as an internal combustion engine sliding bearing alloy layer, its performance is better than the well-known phosphor bronze, tin bronze, lead bronze, Babbitt, aluminum tin, aluminum and silicon aluminum and silicon Cadmium alloy. Al-Si-Cd-Zr alloy. The main chemical composition: Si2
