Problems solved by technology

[0003] At present, the main methods to improve the performance of the optical shaft are: use stainless steel to make the optical shaft, but the price is high, and the wear resistance is not enough; It will produce heavy metal chromium for the second time. After chromium is absorbed by the human body, it has the risk of carcinogenesis and gene mutation. On the other hand, the chromium plating process itself has some limitations in performance; and European and American countries strictly prohibit the import of chromium-plated related products in my country.

Description

technical field [0001] The invention belongs to the technical field of optical shaft processing, and in particular relates to a method for improving the corrosion resistance and wear resistance of an optical shaft. Background technique [0002] Optical shafts include ordinary optical shafts, chrome-plated optical shafts, chrome-plated flexible shafts, stainless steel shafts, and chrome-plated hollow shafts. During use, the optical axis will contact with the optical axis or non-optical axis, and its surface will be worn due to friction; its surface will be rusted due to chemical or electrochemical action when it contacts with the surrounding medium. After the optical axis is corroded and worn, it will affect the transmission performance and precision of the equipment, and seriously restrict the stability of the equipment. Therefore, people continue to study the failure mechanism of the optical axis and take corresponding preventive measures. [0003] At present, the main me...
