How to choose thermal spray repair

In industrial production, surface damage to workpieces is a common problem, especially for workpieces used in high temperature, high pressure or corrosive environments. In order to extend the service life of the workpiece and improve its corrosion resistance and wear resistance, the thermal spraying repair technology has been gradually paid attention to. How to determine whether the surface of the workpiece needs thermal spraying repair, and how to choose the appropriate coating material.

First of all, to determine whether the surface of the workpiece needs thermal spraying repair, the key is to observe the damage of the surface. Common surface injuries include scratches, dents, corrosion and wear. If there are significant scratches or dents on the surface of the workpiece, its structural integrity may be affected, and thermal spray repair should be considered at this time. In addition, if the workpiece surface rust or corrosion phenomenon, especially in chemical corrosion environment, thermal spray repair can effectively prevent further damage.

Secondly, evaluating the use environment and working conditions of the workpiece is also an important factor in determining whether thermal spray repair is needed. If the workpiece is working in a high temperature, high pressure or strong corrosion environment, the risk of surface damage will be significantly increased. In this case, timely thermal spray repair can improve the corrosion resistance and wear resistance of the workpiece to ensure its normal operation.

When selecting thermal spraying materials, it should be determined according to the specific use of the workpiece. Jinan Tianmeng thermal spraying provides a variety of coating materials, such as tungsten carbide, Teflon and so on. Tungsten carbide coating has excellent wear resistance and is suitable for workpieces that need to withstand high friction. The Teflon coating has good corrosion resistance and low coefficient of friction, which is suitable for use in chemically corrosive environments.

When selecting the coating, it is also necessary to consider the material characteristics and operating temperature of the workpiece. For example, for workpieces in high temperature environments, it is important to choose a coating material that is resistant to high temperature. In addition, properties such as adhesion, impact resistance and wear resistance of the coating should also be considered.

Finally, it is recommended to check and maintain the workpiece regularly in order to find the surface damage in time and take corresponding repair measures. Through regular maintenance, the service life of the workpiece can be effectively extended and the production cost can be reduced.

In short, to determine whether the surface of the workpiece needs thermal spraying repair, it is necessary to consider the surface damage, the use of the environment and the characteristics of the workpiece material and other factors. Choosing the right coating material, such as tungsten carbide or Teflon, can significantly improve the corrosion and wear resistance of the workpiece.
