图7－11。臼杯磨损。A：臼的磨损并不按同心圆发展，而偏向于上内方，与承受体重的方向一致，但有10～15o的偏斜角。

At last, transformed the points on the outline of abrasion zone into coordinate through CF function, which included all the information in the zone.

最后通过CF函数，将图像上磨损区域轮廓上的点转换成坐标点，其点准确涵盖磨损区域的信息。

The key of the intermediate treatment lies on the proper saucer leaning with slow corrodent, proper Ar ion bombardment sputtering and pre-deposition of pure titanium layers. Measurement of the adhesion force of the composite coatings verified that all the four TiN composite coatings possess higher adhesion strength when compared with the single TiN coating.

And delamination is the predominant wear mechanism of the coatings.

而剥层磨损是涂层的主要磨损机制。

An abrasive system for use in high cleaning, controlled abrasivity dentifrice compositions comprises at least one abrasive silica which may be selected from a first silica having a Radioactive Dental Abrasion in the range 30 to 150 and a second silica an RDA in the range 100 to 300, and a crystalline aluminosilicate having an average crystallite size below 0.2 mu m.

The dispersoid distribution of the second phase could strengthen the surface of the alloy, which decreased the quantity of abrasive particles. The wear volume of the alloy was decreased. The hardness and strength of the alloy were increased after ECAE. The resistance of deformation was improved and the depth and width of furrows were decreased due to the increase of hardness and strength. As a result, the wear-resistance and tribological properties of the alloy were improved after ECAE.

ECAE热挤压处理显著细化了铝青铜合金的微观组织，弥散分布的第二相对合金起到强化作用，减少了剥落磨粒的数量，降低了合金的磨损量；ECAE热挤压处理的铝青铜合金组织细小，强度和硬度高，提高了合金抵抗塑性变形能力，减轻了磨粒对合金表面的犁削作用，提高了合金的摩擦磨损性能。

2化学镀Ni-P-PTFE复合层具有优异的耐磨性和减摩性，大大改善了Ti-6Al-4V摩擦磨损性能，使Ti-6Al-4V应用于在人工关节以及其它磨损较大的部位成为功效可能。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
