In general, coatings obtained by thermal spray processing cannot be used directly in many cases, such as anti-corrosion coatings. In this case, a series of subsequent processing must be performed. The purpose of the subsequent treatment is to prevent the corrosive medium in the coating from penetrating the pores of the coating to the substrate, thereby causing corrosion of the substrate.

The subsequent treatment of the coating after thermal painting is mainly sealed. The sealing materials include inorganic materials such as paraffin, epoxy resin and silicone resin, and inorganic materials such as oxides. Which one depends on the working medium, environment, temperature and workpiece. cost. In order to improve the bonding strength of the thermal spray coating, the workpiece subjected to high stress load or impact wear should not only be sealed, but also spray remelted, induced remelting, laser remelting, hot isostatic pressing, etc. Remelting of the layer.

After remelting, the thermal spray coating can transform the porous coating mechanically bonded to the substrate into a dense coating that is metallurgically bonded to the substrate, thereby further improving the quality of the workpiece and prolonging the service life. For workpieces with dimensional accuracy requirements, the thermal spray paint should be coated after processing to improve dimensional accuracy and meet user requirements.

In addition, due to the different characteristics of the painted paint coating and the general metal and ceramic materials, the processing of the sprayed layer is difficult. Therefore, reasonable processing methods and corresponding process parameters must be selected to ensure the quality of thermal spraying. Before and after painting, the surface will be different, and it will really play a better role and effect during use.

Everyone's choices are different, and the effect will be different after spraying. We can choose more excellent technology to achieve more protection. Before and after painting, there are some differences in other colors, so when you can try to understand the related things, it is good to find a more professional staff to complete the painting work.
