Abstract

This paper reports the wear behavior of Cu, high Cu-Sn alloy, high Cu-Pb alloy and high Cu-Sn-Pb alloy under dry sliding at ambient conditions. These four materials were chosen for the wear resistance characterization of SnPb-solder affected old/scraped copper (high Cu-Sn-Pb alloy) to explore its reusing potentials. Wear tests were conducted using a pin-on-disk tribometer with the applied load of 20 N for the sliding distance up to 2772 m at the sliding speed of 0.513 ms-1. The applied load was also changed to observe its effect. The investigation reveals that the presence of a small amount of Sn increased the hardness and improved the wear resistance of Cu, while a similar amount of Pb in Cu reduced the hardness but improved the wear resistance. The general perception of ‘the harder the wear resistant’ was found to match partially with the results of Cu, Cu-Sn alloy and Cu-Sn-Pb alloy. Coefficient of friction (COF) values revealed non-linear gradual increasing trends at the initial stage and after a certain sliding distance COF values of all four sample materials became almost steady. SnPb-solder affected Cu demonstrated its COF to be in between that of Cu-Pb alloy and Cu-Sn alloy with the maximum COF value of 0.533.

受snpb焊料影响的铜对不锈钢台面的干滑动摩擦磨损

本文报道了Cu、高Cu- sn合金、高Cu- pb合金和高Cu- sn - pb合金在干滑动环境下的磨损行为。选择这四种材料对受snpb焊料影响的旧/刮铜(高Cu-Sn-Pb合金)进行耐磨性表征，探索其再利用潜力。使用针盘式摩擦计进行磨损试验，施加20 N载荷，滑动距离为2772 m，滑动速度为0.513 ms-1。还改变了施加的载荷以观察其效果。结果表明，少量Sn的加入提高了Cu的硬度，提高了其耐磨性，而等量Pb的加入降低了Cu的硬度，但提高了其耐磨性。“越硬越耐磨”的普遍看法与Cu、Cu- sn合金和Cu- sn - pb合金的结果部分吻合。摩擦系数(COF)值在初始阶段呈非线性逐渐增加趋势，在一定滑动距离后，4种材料的COF值基本趋于稳定。snpb钎料影响Cu的COF介于Cu- pb合金和Cu- sn合金之间，最大COF值为0.533。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
