实验研究表面倾斜方向性微孔表面润滑温升特性。采用环-环摩擦方式，分别在水润滑和油润滑实验条件下，对比分析光滑表面、圆形和倾斜椭圆微孔表面的微孔分布方式和开孔率对摩擦因数和润滑温升的影响规律。实验结果表明：微孔表面的摩擦因数和润滑温升明显小于光滑表面，且倾斜椭圆微孔表面的摩擦因数和润滑温升小于无方向性圆孔表面；微孔分布和表面开孔率对摩擦因数和润滑温升影响明显，径向局部开孔表面比径向全开孔表面具有更小的摩擦因数和润滑温升。

Lubrication temperature rise behavior was investigated experimentally for the micro-inclined-pored surfaces. A comparison among smooth,circle-pored and inclined-ellipse-pored surfaces was performed on a ring-on-ring testing rig under aqueous and oil lubrication conditions respectively,and the influence of the distribution type and area ratio of micro-pores on friction coefficient and temperature rise was analyzed.Experimental results show that the micro-pored surface presents much smaller friction coefficient and temperature rise than the smooth surface,and the inclined-ellipse-pored sur-face has further lower friction coefficient and temperature rise than the circle-pored surface.Both distribution type and area ratio of micro-pores have obvious effect on friction coefficient and temperature rise,and the part-area-pored surface has lower friction coefficient and temperature rise than the full-area-pored surface.
