Surface treatment refers to plating or chemically coating the surface of various materials for the purpose of improving durability and strength. Plating involves forming a thin coating of metal on the surface of metals and resins to prevent corrosion and rust. Plating solutions contain various components such as complexing agents, buffers, and reducing agents in addition to the main metals. In order to stabilize the product and improve productivity, it is necessary to analyze the plating solution periodically during both construction and work. This page provides examples of analysis of plating and other surface treatment types.
