| 2. | The 2014 aluminium alloy treated by 500 solution and 165 ageing has fine alloy phases distributing equably , higher mechanical properties , thus the wear resistance is improved 经500固溶和165时效处理后,其合金相分布细小、均匀,力学性能较高,磨损时,在出现了犁沟的同时,还存在粘著剥落坑,磨痕最浅,耐磨性提高。 |
| 3. | It is different from under point contact that there is no stick area under line contact in the partial slip regime , and load distribution within line contact area is uneven due to roughness of surface 磨痕分析表明,承载区域接触不均匀,存在虚接触区域,其大小与表面粗糙度有关,而接触区域没有不磨损的粘着区,不同于点接触形式。 |
| 4. | In addition , this article also researched the friction marks of steel ball after long - time friction tests with sem images and spectrum analysis , and summarized the principle how to reduce friction and wear of three prescriptions 另外,本文还利用sem图像和能谱分析等手段,对长磨试验后的钢球磨痕情况进行了研究,归纳总结出了三种配方的减摩抗磨和自修复机理。 |
| 5. | 3 . calculating the portion and area of different wear form made by wear methenism with a coding method based on the margin element . and judging the action degree of wear methanism . 4 运用一种基于边素的图像轮廓编码方法,应用图像外围轮廓的编码法计算出不同磨损机制造成的磨痕形状所占的面积及在整个磨损主体中所占比重,判断磨损图像不同磨损机制的作用程度。 |
| 6. | According to the suh ' s theory of friction genesis and based on the change in topography with and without noise , it is assumed that the there is dynamic components of friction force in the area where uneven plowing grooves and pits or adhesive joined asperities are generated 根据噪声与磨痕形貌的关系,本文提出了新的摩擦噪声形成机理:在不规则的犁沟和麻坑或粘着微凸体形成区域,摩擦力有动态成分。 |
| 7. | Secondly , by means of the measurement of the vibration and associated noise , the area in the presence of the friction - induced noise is determined accurately . as a result , a comparative analysis on the topography of the scar surfaces with and without noise is performed in detail 其次,利用动力学和声学测量技术确定了摩擦噪声所发生的区域,在此基础上对磨痕上表面形貌进行了详细的对比分析,发现有噪声区域的形貌明显不同于没有噪声区域的形貌。 |
| 8. | Worn surfaces of sliding pairs were characterized by scanning electron microscopy ( sem ) . chemical compositons on the worn surfaces were analyzed by energy dispersion x - ray analysis ( edax ) , and profiles and suface roughness of the worn surfaces were measured by stylus profilmetry 用扫描电子显微镜( sem )对磨痕表面形貌进行了分析,用能量色散x射线分析( edax )对磨痕表面进行化学成分分析,并用表面轮廓仪测定了磨痕表面粗糙度和磨痕表面轮廓曲线。 |
| 9. | In order to discuss the friction and wear mechanisms of mos2 nanoparticles , it was analyzed that the chemical status of elements existed on the rubbed surface by x - ray photoelectron spectroscope , and it was observed that the surface topography of wear zone by scanning electron microscope 通过x射线光电子能谱仪( xps )分析磨痕表面元素的化学状态,扫描电子显微镜( sem )对磨痕的表面形貌进行分析,从而总结了纳米二硫化钼在n46机械油中的摩擦磨损机理。 |
| 10. | It is observed that the topography of the area with noise on a scar surface is characterized by larger surface roughness , plowing grooves , pits or adhesive joined asperities . while it is found that the topography of the scar after noise disappearance is characterized by a clear polished scar surface and a smaller surface roughness 有噪声磨痕形貌的特征是表面粗糙度比较大、存在不规则的犁沟、麻坑或粘着微凸体;而噪声消失后的磨痕形貌特征是表面粗糙度比较小、有微抛光作用发生。 |
