1Cr13MoS is a kind of material with excellent corrosion resistance and good mechanical properties. Meanwhile, it also has good self-lubricating properties due to the presence of molybdenum disulfide phase inside the material and can be used as friction pair material in the pump. In this paper, the hardness, microstructure, distribution of the self-lubricating phase, friction and wear properties of 1Cr13MoS after heat treatment were studied. After quenching at 1000 °C and tempering at 520 °C, the hardness of 1Cr13MoS prepared by pyrometallurgy is higher than that of HB 350. The tempering sorbite structure is evenly distributed, and the self-lubricating phase MoS is discretely distributed on the substrate with the average size is about 6 μm, which leads to good friction and wear properties. It is worth noting that the 1Cr13MoS is actually operated as friction pair material on the water pump and has a significant wear improvement effect compared to the conventional 12% chrome steel series.
1Cr13MoS是一种具有优异耐腐蚀性和良好力学性能的材料。同时,由于材料内部存在二硫化钼相,它还具有良好的自润滑性能,可作为泵中的摩擦副材料。本文研究了1Cr13MoS热处理后的硬度、微观结构、自润滑相分布、摩擦磨损性能。在1000℃淬火和520℃回火后,火法冶金制备的1Cr13MoS硬度高于HB 350。回火索氏体组织均匀分布,自润滑相MoS2离散分布在基体上,平均尺寸约为6μm,使其具有良好的摩擦磨损性能。值得注意的是,1Cr13MoS实际作为水泵的摩擦副材料运行,与传统的12%铬钢系列相比,有显著的磨损改善效果。
