磨损

N this research, the characteristic of martensitic steel in abrasion was investigated by using three different test methods.

本研究通过3种磨料磨损试验方法，对0.20％，0.39％，0.78％，0.98％4种合碳量马氏体钢的磨料磨损特性进行了考察。

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.

结果表明，复合材料涂层与基体形成良好的冶金结合，微观组织细小、均匀；复合材料涂层硬度达400HV，约为基体的2.5倍；在室温油润滑条件下，滑动磨损试验表明复合材料涂层摩擦系数和失重均小于基体，磨损表面划痕较浅且平滑，无明显的犁沟、粘着、剥落现象；激光表面合金化显著提高了材料的耐磨性。

Thankfully the Nokia E71 isn't exposed to wear and tear much, since its back cover is all metel, while the body is made of glossy plastic that won't wear off with time.

幸好诺基亚e71是不是暴露了磨损得多，因为它的封底是所有金属，而该机构所作的光滑塑料将不会磨损小康与时间。

In this article, three kinds of prealloy powder were developed by water atomization method. The base attribute, pattern, phase composition, differential thermal analysis of powder were researched. Sintered density, hardness, bend strength, Young's modulus were researched as hot pressed sintering temperature changing. By using abrasive wearing equipment upbuilt by the authors, the wear resistance were determined. Green-pressing density, simulated green-pressing strength and bonding momental of high frequency brazing were assayed. SEM corrosion structure and SEM appearance of fracture were observed.

It is found that the resistance of the material to micro-fracture is consistent with the increase of the monoclinic phase cont...

结果表明：材料的磨损抗力与磨损面上单斜相增量呈一致增加的关系。

Nano-imprint lithography drum paper teeth axis, swayig begnawing workparts paper teeth or wear, allows unleashmy begnawing paper teeth in paper in an inconsistent state in that result in bilateral irregular longitudinal misregister, in which case on slow computers are more likely to occur, because the impact of low-speed machine tipping bucket, the strength of a rotational motion paper teeth ranges of swayig high speed machine is used, and indirect sheet transfer unleashmy simpleplan paper teeth have smaller, at the same time as a result of automatic circulation lubrication oil system, unleashmy and apparatdus paper teeth axis is not easy to wear, but bearing in mind that oil, oilway jam torn oil grinding.

压印滚筒咬纸牙轴，摆动咬纸牙轴或轴套磨损后，不离使得咬纸牙在咬纸功程洋处于不稳不退状况，以至于爆发双边无次序的纵向套印禁绝，这栽环境在不低速机上比辛便当呈现，因为不低速机翻斗撞击辛不小，咬纸牙轴动弹幅度比辛不小，不低速机是拔取摆动不直接递纸，并且咬纸牙闭合幅度也较小，同时又由于有被迫轮回油路编制润滑，所以咬纸牙轴及轴套不便当磨损，但给夺目油眼，油路畅通导致不续油咬不松。
