采用传统Tafel 拟合计算得出腐蚀速率。与未微合金化的锰黄铜相比，锆微合金化的锰黄铜腐蚀速率降低了74.5%，说明其电化学耐蚀性更好。

摩擦磨损性能 

通过锰黄铜在室温下的湿摩擦系数随磨损时间变化曲线可以看出，未合金化和锆微合金化的湿摩擦系数变动幅度均较小，都有较优的耐磨性能。但是锆微合金化的锰黄铜具有更低的平均摩擦系数(0.0254)，与未合金化的锰黄铜(0.0315)相比降低了19.3%。

通过锰黄铜的磨痕形貌可以看出，摩擦后的表面特征有如下几点：

①沿滑动方向上存在着明显的犁沟，犁沟深且多；

②犁沟旁边均出现了部分承载面。说明该区域在摩擦力的作用下发生了塑性变形，但没有发现裂纹，表明无脆性断裂现象 [3]  。

力学性能 

Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand

column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor

differences. The column in the middle states the norm and its country of origin.

With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.
