划痕

Try pinching the skin near the itch between your thumb and forefinger through your clothing; this is less damaging than actual scratching.

尝试的Pinching皮肤附近的七年之痒之间您的拇指和食指通过您的衣物；这是少损害比实际划痕。

Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

结果表明：碳纳米管作为润滑油添加剂表现出优良的抗磨性能，在质量分数仅为0.0125%～0.1000%时，润滑油的抗磨性能显著提高；在质量分数约为0.0500%时其抗磨效果最佳，磨损率降低幅值达57%；在较高载荷下，添加0.0250%的碳纳米管能够使其摩擦系数减小约15%，但随着碳纳米管质量分数的增加，摩擦系数迅速提高；含碳纳米管润滑油的磨斑表面平整，划痕较细且分布均匀。

The precision lapping technology to machine the copper substrate using semi-fixed abrasive plate was studied. The surface roughness and material removal rate as the evaluation of indicators, the influences of the different lapping parameters on the surface roughness and material removal rate were discussed and analyzed. Experimental results indicated that the copper substrate could be efficiently machined by semi-fixed abrasive plate of 800(superscript #) SiC abrasive, and the initial roughness Ra of a machined surface could be improved from 0.553μm to 0.28μm in 10min, produced an ideal rarely scratch surface. Then processed copper polished by diamonded grinding paste, it could be satisfied for the Ni-Pd-P alloy thin film growth.

主要研究半固着磨具精密研磨非晶态Ni-Pd-P合金薄膜铜片衬底，以铜片衬底的表面粗糙度和材料去除率为评价指标，探讨了研磨过程中不同的工艺参数对铜片表面粗糙度和材料去除率的影响结果表明：用800 SiC半固着磨具对铜片衬底进行研磨加工，10min后铜片表面粗糙度Ra可由0553μm减小到0.28μm，同时表面无深划痕：加工后的铜片再经金刚石研磨膏抛光可快速获得满足Ni-Pd-P合金薄膜生长用的铜片衬底表面。
