摘要
采用MG-2000高速高温摩擦磨损试验机,用正交设计试验方法研究凹坑形非光滑表面形态的耐磨性,选取温度、凹坑直径和凹坑间距作为试验因素,每个因素选取2个水平。试验结果表明,在本次试验条件下,温度对非光滑试样耐磨性影响最大,凹坑直径其次,凹坑间距最次,这为凹坑型非光滑表面尺寸和分布密度的选取提供了初步的试验数据。
The wear resistance of W9Cr4V high speed steel with non-smooth surface was studied by the method of orthogonal design using MG-2000 wear test machine.The model specimens made of W9Cr4V high speed steel with regular concaves were processed by Laser texturing technology.Temperature,concave diameter and concave distance were taked as test factors,each factor selected 2 levels.The test results show that temperature is the biggest influence on wear resistance of non-smooth concave specimen,concave diameter is secondly,the concave distance is not obvious.The test results provided a preliminary experiment date for the selection of non-smooth surface size and density distribution.
