摘要
作者从摩擦学角度出发,对PVD TiN等6种典型表面强化层的摩擦学性能进行了系统的试验研究。结果表明,几种表面强化层各有其最佳的应用范围和各自的磨损机理。不同强化层的承载能力不同,失效形式亦各异,配磨材料对其摩擦学特性有明显的影响,最佳强化层的耐磨性不代表配副系统的最佳耐磨性。
The tribological properties of six surface enhanced layers
which are of wide use at home and abroad were investigated using systemic analysis and modern microscopic examination. The wear tests of the friction pairs in which several surface enhanced layers are coupled with 40Cr or GCr15 were conducted, the test conditions are as follows: 500N of load, 0.42m/s of sliding speed, 10 hours of testing time and 20 machinery oil for lubrication. The test results were shown in Table 1 and 2.
According to the results of Table 1 and 2, it can be seen that the an-tiwear properties of both sides of the pairs must be considered so as to select the friction pairs. If one side is of the good antiwear property, whereas the wear of the other side is high, this friction pairs is not available for practice application.
The advantages and disadvantages of the six surface enhance proces-ses were analized and its application area was also discussed in this paper. Table 1 The wear test results of six surface enhanced layers coupled with 40Cr
Table 2 The results of wear test of friction pairs in which the five Surface enhanced layers are coupled with GCr15
