Then, it analyses the effects on some natural parameters such as alloy transfer coefficient, surfacing layers, welding current and arc voltage etc.. It confirms the fitting ageing technique. Also, it discusses the microscopic structural transformation back and forth ageing and the effects on hardness change of overlaying metal by some alloying elements including C, Cr, V, W, Mo, Ni, Mn, B, Re through OM, SEM and X-ray diffraction analyses. Finally the abrasive resistance, red hardness, thermal fatigue property and anti-high temperature oxidability are investigated in experimentation.

In addition, a printing plate edge marked slopes or plate is too thin, or short-run printing of excessive wear lighter, so that the short-run suites and whitespace differences of high and low is too low and too soft pads, resulting in suites blank areaand, electro-chemical layer of aluminum foil, etc, should be made at the edge version slope near 90-degree right-angle (such as seihan with carving techniques that help you make little gradient edge version), according to the characteristics of the short-run suites, with thickness larger plate seihan, and a blank site, using a corrosion deeper stereoplasm lining for short-run; in addition, you should choose thin aluminized layer of anodized, adjust the appropriate business card printing and membership card making and adjusted pressure volume drum uponsize pressuer letoff drum.

此外，印版边沿存在明显的斜坡度或版材太薄，或印版过量烫印磨损变浅，使烫印版面与空白的高低差异太小，衬垫材料过软，造成版面空白部位与电化铝箔层接触等，应将版边沿坡度制成近90 度的直角(如采用雕刻工艺进行制版，可使版边沿几乎没有坡度)，根据烫印版面的特点，采用厚度大一些的版材制版，并将空白部位腐蚀深一点，采用硬质包衬进行烫印；此外，应选择镀铝层较薄的电化铝，调整合适的制卡和会员卡制作压力，并适当调整压卷滚筒压力和收卷滚筒拉力。

The unsmoothed characteristics of some living beings in soil have wear reduction and wear resistance function . The research benefits the revelation that a tungsten carbide reinforced Cu-base alloy wear-resistant composite coating was produced on mild steel by spark plasma sintering.Under the condition of two bodies abrasive wear ,the coating with the structure that hight hardness and good wear resistance WC particles embedding in tough fine Cu-base alloy matrix resist the abrasion wear and manifest the good wear reduction and wear resistance properties that the unsmoothed bodysurface of some living beings in soil have.

The higher the thermal diffusivity and bonding strength between lamellae, the more wear-resistant the coating.

涂层的导温系数和层状颗粒相互之间的结合强度越高，层状颗粒的厚度越厚，其抗粘着磨损性能越好。

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。

In the paper a nanocrystalline surface layer with better tribological behaviors is fabricated on coarse-grained Cu matrix.

由于摩擦磨损总是发生在接触表面区域上下很薄的一层材料之中，材料的摩擦学特性直接决定于这层材料的物理化学特性，往往脱离整体材料的基本性能。
