在实验的基础上对湿磨料磨蚀的机理进行了探讨。认为在湿磨料磨蚀情况下,由于磨料对材料的作用应力不同,会使材料的耐磨性出现很大的变化。因此认为有必要将湿摩料磨蚀分为两类一高应力湿磨料磨蚀及低应力湿磨料磨蚀。在前面的情况下,铜的耐磨性与其硬度(强度)有关;但在后面情况下,硬度并不起作用,而钢的耐腐蚀性却起决定作用。钢在湿磨料磨蚀时,由于磨料的作用,使其表面经常处于活泼状态。根据计算,新暴露表面的碳钢在水中的瞬时腐蚀率要比通常在不含磨料的流动水中的腐蚀率大2个数量级。文中并用示意图表示出钢的湿磨料磨蚀机理。
Based on the experiment, the mechanism of wet abrasive abrasion was discussed. It is considered that under the condition of wet abrasive abrasion, the abrasion resistance of the material will greatly change due to the different stress on the material by the abrasives. Therefore, it is considered necessary to classify wet abrasives into two types of high-stress wet abrasive abrasives and low-stress wet abrasive abrasives. In the former case, the wear resistance of copper is related to its hardness (strength); in the latter case, however, the hardness does not work and the corrosion resistance of the steel is decisive. Steel in the wet abrasive abrasion, due to the role of abrasive, so that the surface is often in an active state. It has been calculated that the instantaneous corrosion rate of freshly exposed carbon steel in water is two orders of magnitude greater than the corrosion rate normally found in abrasive free flowing water. The paper also shows a diagram of the wet abrasive abrasion mechanism of steel.
