仪器生产中有并多几何形状复杂、尺寸小、薄片(δ=0.1)的不锈钢(1Cr18Ni9)零件需要抛光。采用机械抛光,不易保赶几何形状,尤其是薄片零件,其变形特别大。为了解决这一关键,我们试验了电抛光工艺,它还有这些优点:(1)消除表面冷作应力,这对薄片形零件尤其重要;(2)能生成细密均匀的氧化膜;(3)设备简单,生产率高,不需要熟练工人即可操作。现将不锈钢电抛光介绍于下。一、原理将零件挂在一定组成的电解溶液中,工件接阳极,
Stainless steel (1Cr18Ni9) parts that have many and complex geometries and are small in size and thin (δ = 0.1) need to be polished. Mechanical polishing, not easy to keep the geometric shape, especially the sheet parts, the deformation is particularly large. In order to solve this problem, we tested the electropolishing process, which also has these advantages: (1) to eliminate the surface cold stress, which is especially important for the lamellar parts; (2) to produce a fine uniform oxide film; (3) Simple equipment, high productivity, does not require skilled workers to operate. Now stainless steel electric polishing introduced below. First, the principle of hanging parts in a certain composition of the electrolytic solution, the workpiece then the anode,
