How Does The Supersonic Process Control The Coating Thickness Method

The key to control coating thickness in supersonic spraying process is to adjust spraying parameters and moving speed of spray gun. Here are some specific control methods:

1, Adjust the spraying distance: the distance between the spray gun and the substrate will affect the deposition rate of the coating, and the coating thickness can be fine-tuned by changing this distance.

2, control the spraying speed: the moving speed of the spray gun determines the area covered by the coating material per unit time, speeding up the moving speed will reduce the coating thickness, slowing down will increase the coating thickness.

3, adjust the spraying power: the power of the spraying equipment will affect the heating degree and speed of the coating material, and then affect the thickness of the coating.

4, powder supply rate: Adjust the amount of powder into the spray gun can control the thickness of the coating, too much powder supply will lead to too thick coating, insufficient supply is too thin coating.

5, multiple spraying: by controlling the number of each spraying and the repeated superposition of the coating, the required total coating thickness can be accurately achieved.

6, the use of automated control systems: Modern supersonic spraying equipment is usually equipped with automated control systems that can monitor and adjust the spraying process in real time to ensure consistency and accuracy of coating thickness.

The above method allows operators to precisely control the thickness of the coating in the supersonic spraying process according to the specific requirements of the workpiece and coating standards.
