摘要/Abstract

摘要： 本文提出了一种类喷丸润滑工艺，即喷丸和润滑工艺的结合。在这个过程中，待处理的试样、合金丸和固体润滑粉末一起在滚筒中旋转。由于丸料的冲击而形成的表面凹坑可以储存润滑剂，而润滑剂也可以通过撞击粘附在试样表面。采用13个实验方案，研究了滚动时间、转速、合金丸的质量和丸的直径等工艺参数对钢试样表面形貌的影响。定量分析了试样规定区域内表面凹坑的分布比例和平均深度。进一步采用MoS2固体润滑粉末的四个方案对圆柱形钢坯进行润滑，并使用稳定的前后挤压组合试验来评估润滑效果。结果表明新型类喷丸工艺的摩擦系数小于传统磷酸盐-肥皂涂层工艺。

Abstract: A blasting-like lubricating process (combination of shot blasting and lubricating processes) is proposed. In this process, the specimens to be treated, alloy shots, and solid lubricating powder are rotated together in a roller. The surface pockets formed due to the impact by the shots can store lubricants, and the lubricant can also adhere to the specimen surface by hitting. The effects of process parameters, including rolling time, rotational speed, mass of alloy shots, and the diameter of shots, on the surface topography of the steel specimen are investigated using 13 experimental schemes. The distribution ratio and average depth of surface pockets on the defined areas of the specimen are quantitatively analyzed. Four selected schemes with the MoS2 solid lubricating powder are further carried out to lubricate the cylindrical billets, and the lubricating effect is evaluated using the steady combined forward and backward extrusion test. The indicated friction factor of the novel blasting-like process is smaller than that of the conventional phosphate-soap coating process.

Key words: blasting-like process, lubricating, surface pocket, friction factor, cold extrusion
