摘要: To study the effect of irregular topography on friction performance of mold surface, chemical etching method, which is simple and cost-effective, was used to get three kinds of irregular surface topography of cold work die steel Cr12. Then friction and wear experiments on samples with smooth surface topography and irregular surface topography were done in oil-starved condition respectively and friction coefficient and wear morphologies were got through the tests. The results demonstrate that irregular surface topography can reduce the friction coefficient effectively. Friction coefficient varies with the density of asperity peak contacts, that is with a certain surface topography, the more asperity peak contacts there are, the smaller the friction coefficient and the wear are. With the increase of the size and depth of corrosion pits on the surface, friction coefficient experiences a fluctuation from increase to decline. Samples' surface hardness has a relative improvement after corrosion, which enhances their abrasive resistance.
