随着铅含量增加，合金的摩擦系数与磨损率显著下降，尤其铅含量为2 0 %与2 5 %的合金抗咬合性能明显提高。
The friction coefficient and wear rate decreased with increasing lead content, especially the anti seizure property of al Pb alloys containing 20wt. % and 25wt. % lead was improved remarkably.
对比试验表明，所研制的制动材料摩擦系数稳定，抗衰退性能好，磨损率较小，具有较大的性能价格比优势。
Test results show that the developed brake composites have fairly stable friction coefficient, good fading resistance, low wear rate and...
