This paper studies the change of impact fatigue wear pattern with material characteristics and impact time. The worn surface, wear debris and sub-surface of impact wear samples are analysed comprehensively, and the process of impact fatigue wear is suggested.

研究了低合金钢的冲击疲劳磨损随材料特性和冲击时间的变化规律,全面分析了冲击疲劳磨损试样的磨面、磨屑和亚表层,提出了冲击疲劳磨损的过程。

The paper deals with the wear behaviour of boron-zirconizing layer and boronizing layer of 5CrMnMo steel during abrasive and impact fatigue wear tests. The results show that the wear resistance of the boron-zirconizing layer is superior to that of the boronizing layer under both abrasive wear and impact fatigue wear conditions. The reason is that the brittleness of the boron-zirconizing layer is lower than that of the boronizing layer. Both the boronized sample and the boron-zirconized sample were quenched isothermally....

The paper deals with the wear behaviour of boron-zirconizing layer and boronizing layer of 5CrMnMo steel during abrasive and impact fatigue wear tests. The results show that the wear resistance of the boron-zirconizing layer is superior to that of the boronizing layer under both abrasive wear and impact fatigue wear conditions. The reason is that the brittleness of the boron-zirconizing layer is lower than that of the boronizing layer. Both the boronized sample and the boron-zirconized sample were quenched isothermally. Their impact fatigue wear resistance can be improved evidently by comparison with that of the same sample without the same processing of isothermal quenching. The result obtained is considered to be the diminution of the residual stress and the strengthening of the transition zone. The wear mechanism, in the present paper, indicates that the behaviur of abrasive wear is operated by plastic deformation and ploughing, and that of impact fatigue wear by a compound mechanism which involves impact fatigue, slide and abrasive.

本文研究了5CrMnMo钢的硼锆共渗层与渗硼层在磨粒和冲击疲劳磨损试验时的磨损行为。结果表明,在磨粒和冲击疲劳磨损条件下,共渗层的耐磨性比渗硼层的优越,其因在于共渗层脆性比渗硼层的低。共渗与渗硼后经等温淬火的试样比不经等温淬火的试样,其冲击疲劳下的耐磨性得到明显地改善,可认为是残余应力降低与过渡区强化的结果。本试验中的磨损机制,磨粒磨损是塑性变形与犁削机制,冲击疲劳磨损则是冲击疲劳、滑动与磨粒磨损的复合机制。

The authors analyze the service life of the valve and valve seat of a drill pump by mathe matieal statistics,figure out that the distribution of the service life of valve and valve seat accords with two-parameter weibull distribution,and think that the failure of the pump valve is caused first and foremost by impact fatigue wear and afterwards by destructive erosion.

用数理统计方法对钻井泵泵阀阀体、阀座的使用寿命进行了分析,得到阀体、阀座的使用寿命分布规律服从于二参数威布尔分布。认为泵阀的失效过程通常是先产生冲击疲劳磨损,后形成冲蚀破坏,整个失效过程又是以冲击疲劳为主。
