为了建立纳米抗磨添加剂自修复性能的评价标准,提出了以磨损试验后试块质量增重为衡量依据的实验设想.以商品纳米Cu抗磨自修复剂作为考察对象,在高速环块磨损试验机上,发现了在不同试验力、转速、试验时间和添加剂浓度等试验条件下,试块摩擦增重的变化规律,从而提出了对添加剂自修复性能进行评定的试验方法和条件,并进行了重复性和再现性测试.通过扫描电子显微镜、X射线能量色散谱仪等对磨痕表面形貌和元素的分析,证实了添加剂的抗磨自修复性能和评价方法的可行性.
In order to establish the evaluation criteria of the self-healing properties of nano-anti-wear additive, the experimental assumption based on mass weight gain of test block after wear test was proposed.With the commercial nano-Cu anti-wear self-healing agent as the object of study, Machine, and found that under different test conditions, speed, test time and concentration of additives and other test conditions, the change of friction weight of the test block, and thus proposed additive self-healing properties of the test methods and conditions were assessed and repeated Sexual and reproducibility tests.Analysis of surface morphology and elements of wear marks by scanning electron microscopy and X-ray energy dispersive spectroscopy confirmed the anti-wear self-healing properties of additives and the feasibility of evaluation methods.
