Problems solved by technology

For the processed products of cobalt chromium metal, if the salt solution composed of ammonium sulfate is used, the processed products will have poor surface brightness and roughness. However, after prolonging the processing time to improve the polishing effect, the result is still not ideal, and may even cause Damage to the workpiece, such as burnt black, notch phenomenon, etc.

Abstract

The invention discloses a polishing solution for cobalt-chromium metal electrolyte plasma polishing. The polishing solution comprises the following preparation raw materials of, in parts by weight, 5-15 parts of sulfate, 0.1-2 parts of organic acid and 150-300 parts of water. The polishing solution for cobalt-chromium metal electrolyte plasma polishing is specially used for the development of cobalt-chromium metal workpieces, and processing operation does not influence the application performance of a to-be-polished metal accessory in a specific field; after being polished, the workpieces arebright and glossy, and the surfaces of the workpieces is smooth and sand-free; and the processing efficiency is improved, and the damage such as burning black and notches of the workpieces are avoided.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a polishing liquid for cobalt-chromium metal electrolyte plasma polishing. Background technique [0002] Electrolyte plasma polishing technology is a "green" special processing method for high-quality and efficient metal polishing. It is generally used for polishing in industrial manufacturing. The main processed product is stainless steel. The polishing solution is a low-concentration salt solution, the most common material. Ammonium sulfate (NH 4 ) 2 SO 4 Solution, ammonium sulfate is weakly acidic, easily soluble in water, has good conductivity, and is the main component of chemical fertilizers. The polishing solution with ammonium sulfate as the main component will not cause environmental pollution and other problems. [0003] With the diversification of processed products, the existing polishing fluid cannot adapt to all processed products, such as cobalt chromium metal. ...
