研究了不同含量水平高温条件下钢纤维、芳纶浆粕、六钛酸钾晶须及腰果壳粉等增强组分对半金属摩擦材料复配体系摩擦学性能的影响。针对摩擦试样的摩擦因数及其在高温区的抗磨损情况，按照低摩擦磨损要求，获得优化配方。通过扫描电子显微镜观察分析磨损表面形貌及磨损机理。结果表明：钢纤维对摩擦因数和磨损率影响均显著，芳纶浆粕对磨损率的影响较显著但对摩擦因数影响较弱，腰果壳粉与芳纶浆粕相反，六钛酸钾晶须对磨损率和摩擦因数影响均不显著。添加钢纤维、芳纶浆粕、六钛酸钾晶须及腰果壳粉的质量分数为12%、2%、4%、5%试样的摩擦稳定性最好，摩擦因数在0.45±0.07，350℃时高温磨损率最小，复配体系的磨损机理与增强组分的含量密切相关。

The orthogonal experimental study is carried out to study the incorporation of different proportion of functional components and the effect on tribological performance among semi-metallic friction materials. The friction factor and high-temperature abrasion resistance properties are evaluated along with the obtaining of optimal formula, and the mechanism of affecting the tribological properties is analyzed. The study results indicate that the inlfuence of steel ifber, kevlar pulp, potassium hexatitanate whisker and cashew nut shell on the friction coefifcient and the wear rate were different. The friction stability is better to be around 0.45 ± 0.07, when the adding amount of steel ifber, Kevlar pulp, potassium hexatitanate whisker and cashew, nut shell are 12%, 2%, 4%, 5%, and the abrasion rate at high temperature of 350℃. The mechanism of action is closely related to the component content.
