一种用于不锈钢制轴承零件表面磨削烧伤检测的酸洗腐蚀方法
摘要：
一种用于不锈钢制轴承零件表面磨削烧伤检测的酸洗腐蚀方法，它涉及一种轴承零件表面磨削烧伤检测的酸洗腐蚀方法。本发明是为了解决现有不锈钢零件酸腐蚀检测时所使用的去灰溶液中含有铬酐，污染环境的技术问题。本方法：上挂、抖动清洗、热水洗、冷水洗、水膜连续检查、酸腐蚀、流动冷水洗、去灰、一次流动冷水洗、二次流动冷水洗、防锈、下挂、烧伤检查。采用本发明方法对磨加工后的不锈钢(9Cr18、9Cr18Mo)制轴承零件进行酸洗检查，可以有效检查和控制磨削烧伤，保证该轴承的使用寿命和可靠性。同时优化了步骤、降低了成本、利于生产控制、达到了环保要求(取消了禁限用的铬酐)。本发明属于不锈钢制轴承零件表面磨削烧伤检测的技术领域。
摘要（英）：

The invention discloses a pickling corrosion method for detecting a grinding burn on the surface of a stainless steel bearing part, relates to a pickling corrosion method for detecting a grinding burnon the surface of a bearing part, and aims to solve the technical problems that a used deashing solution contains chromic anhydride and pollutes the environment during detection of acid corrosion ofa stainless steel part in the prior art. The method comprises the following steps of racking, shaking cleaning, hot washing, cold washing, continuous water film inspection, acid corrosion, flowing cold washing, deashing, primary flowing cold washing, secondary flowing cold washing, rust prevention, sagging and burn inspection. The method disclosed by the invention is adopted to carry out picklinginspection on the stainless steel (9Cr18, 9Cr18Mo) bearing part subjected to grinding machining, so that the grinding burn can be effectively checked and controlled, and the service life and the reliability of the bearing are guaranteed; and moreover, the steps are optimized, the cost is reduced, production control is facilitated, and an environmental protection requirement is met (the forbidden chromic anhydride is canceled). The invention belongs to the technical field of detection of the grinding burn on the surface of the stainless steel bearing part.
