并用扫描电子显微镜观察了材料摩擦表面磨痕形貌。

The wearing surface of the friction material was examined by scanning electron microscope .

而UHMWPE-ALN1.0wt%的摩擦系数与磨痕体积有显著增加，微观形貌出现大量松散的无定向纤维，与UHMWPE表面的片状磨损有显著差异。

Whereas , the friction coefficient and volume of wear scar of UHMWPE-ALN 1.0 wt % increased significantly . A lot of non-oriented loose fibrils accumulated on the worn surfaces of UHMWPE-ALN 1.0 wt % while some sheets-like peelings appeared on UHMWPE .

并对摩擦后的磨痕进行了SEM分析，发现：（1）在200N，300℃时出现了粘压的多源弧形裂纹，这和冲击时的沿树枝晶裂纹截然不同；

The wear scar after 15 000 cycles was analyzed by SEM . The results show : ( 1 ) there is multi sources arc crack at 200N , 300 ℃, it is different to impact crack with tree shape ;

测试不同填充量Al2O3对PEEK硬度和表面润湿性的影响，评价了蒸馏水润滑条件下的摩擦学性能，用光镜观察了材料摩擦表面的磨痕形貌。

The effect of nano-Al2O3 mass fractions on the hardness and contacted angle of the reinforced PEEK composites was investigated . Tribological properties of composites under distilled water lubrication condition were measured on an MM-200 tribometer . And the morphologies of the worn surfaces were observed with optical microscope .

金属往复滑动条件下摩擦噪声与磨痕形貌关系的探讨（3）通过改变位移的幅值和频率来进行不同滑动速度下的摩擦噪声试验；

Further Discussion on the Correlation between Friction-Induced Squeal and Surface Topography with and Without Squeal Under Metal Reciprocating Sliding Different velocities or waveforms of reciprocating sliding are applied .

结果表明，在微动磨损向往复滑动磨损转变前后，除磨损系数出现突变外，摩擦系数和磨痕的轮廓形貌也发生了比较大的变化，磨损转变过渡区的范围为70～100μm。

The results show that in addition to wear coefficient friction coefficient and wear mark morphology also have to some extent changes before and after the transition . A transition probably occurs between 70 μ m and 100 μ m under the present conditions .

与UHM-WPE相比，UHMWPE/PP/CB/CF复合材料的摩擦因数和磨痕宽度分别下降了10%和44%，UHMWPE/PP/CB复合材料则分别下降了12%和42%。

When content of fillers is 5 % , the friction coefficient and wear width of UHMWPE / PP / CB / CF and UHMWPE / PP / CB composites respectively decrease 10 % , 44 % and 12 % , 42 % compared with UHMWPE .

对摩擦表面进行了宏观形貌分析和傅立叶红外光谱分析，结果表明摩擦表面磨痕浅而稀疏，有磨损自补偿膜形成。

The analysis of Image View and IR shows that the trace of the friction surface is shallow and sparse , and forming the wear self-compensation repairing organic film .
