微造型对滑动轴承摩擦学性能影响的研究

基于N-S方程,利用ANSYS中CFX模块,进行微造型滑动轴承计算流体力学(CFD)分析,着重讨论微造型的几何参数、密度、位置对滑动轴承摩擦学性能的影响。研究结果表明:适当减小微造型的深度或长度、适当增加微造型的宽度有利于增加轴承的最大压力和承载能力、减小轴承的摩擦系数;存在使得轴承承载能力最大或摩擦系数最小的最优微造型密度;在油膜最大压力附近布置微造型,更利于增加轴承承载能力、减小轴承摩擦系数。

Tribological properties of nanostructured n -Al2O3/Ni coatings deposited by plasma spraying

Nanostructured n-Al₂O₃/Ni feedstock for thermal spraying was manufactured by the method of chemical wrapping and spray drying. The nanostructured coating was sprayed with this feedstock. Tribological properties of the coatings and steel 45# were tested. Within the testing range, the friction coefficient of coatings against GCr15 steel decreased and the mass loss of coatings increased at first then decreased with the increase of load. Under each load, the coatings’ fraction coefficients and wear losses were lower lower than that of steel 45#. Scanning electron microscopy and energy dispersive spectrometer analysis show that adhesion is the dominating wear mechanism, and fatigue exists at the same time. Material transferred from counter-part to the coating is the main factor which influences the coatings’ friction coefficient and wear losses.     

Mechanical properties and tribological behavior of a cast heat-resisting copper based alloy

Mechanical properties and tribological behavior of a novel cast heat-resisting copper based alloy are investigated. The corresponding properties of a commercial aluminum bronze C95500 (ASTM B30) are compared with the alloy. The results show that the alloy possesses better mechanical properties and tribological behaviors than that of C95500 at elevated temperature. The tensile strength, elongation and hardness at 500℃ are 470MPa, 2.5% and HB220, respectively. The wear rate of the developed alloy at ambient and elevated temperature is about one-sixth and one-fortieth of that of C95500, respectively. The alloy is very suitable for ma-nufacturing heat-resisting and wear-resisting parts. Major strengthening mechanisms for the alloy are solution strengthening and the second phase strengthening.

水溶性稀土络合物结构对摩擦学性能的影响

合成了5种具有不同碳数的水溶性烷在酚（或醇）聚氧乙稀醚磷酸酯稀土铈络合物,利用四球机试验考察了它们的摩擦学性能;并采用俄歇（Auger）电子能谱考察了摩损表面上的元素成分。实验结果表明,人水溶性稀土络合物中的碳数及氧乙烯链（C2H4O）的含量对摩擦学性能有较大的影响,碳数较多的稀土络物（特别是C12～C18)的抗磨性能和承载力均好。Auger能谱的分析显示出该类稀土络合物的抗磨性能与摩擦表面中存在铈、磷等活性元素有关。
