During the whole process of hand-slab processing, most of the hand-made plates undergo surface treatment through appropriate processing methods (CNC or 3D printing). The purpose of the surface treatment is to satisfy corrosion resistance, abrasion resistance, decorativeness or other SP requirements. The product features a full range of functions and there are dozens of processing techniques for the prototyping processing. As a large-scale hand-saw factory, RMT PRODUCTS CO., LTD can provide most of the surface processing requirements for manual processing, and has a standardized production process. Next, it introduces the surface treatment technologies commonly used in manual processing.

Under certain conditions, when the metal potential moves in the positive direction due to the applied anode current or local anode current, the surface state of the original active dissolved metal will suddenly become large, and the dissolution rate of the metal will rapidly decrease. This surface state is called passivation.

     Passivation can improve the passivation performance of metal materials, promote the passivation of metal materials in the environment, and increase the mechanical strength of metals. It is one of the most effective ways to control corrosion and increase metal and coating adhesion.
