What are the surface treatments and polishing of metals?
梦幻岛
As we all know, metal alloys are widely used in our lives, from screws, cans, smart watch dials, to aerospace fields such as aircraft and rockets. In industrial production, metal products need to go through a series of processing procedures to obtain products that meet the requirements.
Today, metal Surface Finishing processes generally include spraying, electroplating, wire drawing, sandblasting, anodizing, passivation, oxidation, polishing, etc. Among them, the polishing process has the greatest influence on the metallic luster. There are many kinds of polishing processes, such as manual polishing, vibration polishing, magnetic polishing, electrolytic polishing, chemical polishing, etc.
In today’s industrial production, the most common processes are electrolytic polishing, magnetic polishing and chemical polishing.
In electropolishing, the anode is the workpiece to be polished, and the inert metal acts as the cathode. The two poles are placed in the electrolytic cell, and the anode-polished workpiece is dissolved by direct current, so as to remove the unevenness on the surface of the workpiece and achieve better brightness.
