Wear reduction is critical in the automotive industry, where efficiency, part life, and environmental factors are of concern. Generation of tribofilms by additive-infused lubricants has been effective in reducing wear, and the continued progress of ashless tribofilms offers a promising solution for better protection. A group phosphorus- and sulfur-containing tribofilms were characterized to assess their chemical and mechanical properties in relation to wear protection. Gears were run through modified L-37 with different additive formulations, and were analyzed by EDS, AFM, and nanoindentation. It was discovered that phosphorus and sulfur were well correlated with wear performance, with higher phosphorus and lower sulfur offering better protection. Mechanical testing revealed that a higher elastic modulus was also strongly correlated to better wear performance.

在关注效率，零件寿命和环境因素的汽车工业中，减少磨损至关重要。通过添加添加剂的润滑剂产生的摩擦膜在减少磨损方面是有效的，无灰摩擦膜的持续发展为提供更好的保护提供了有希望的解决方案。对一组含磷和硫的摩擦膜进行了表征，以评估其与磨损防护有关的化学和机械性能。使齿轮通过具有不同添加剂配方的改良L-37，并通过EDS，AFM和纳米压痕进行分析。发现磷和硫与磨损性能密切相关，较高的磷和较低的硫提供更好的保护。
