Supersonic spraying of nickel-chromium alloy coating on the surface of the bushing

       Nickel-chromium alloy is also one of the commonly used spraying wires in the thermal spraying process. Its high temperature resistance strength is higher than that of iron-chromium-aluminum alloy, and it is resistant to high temperature. It is not easy to be deformed under high temperature conditions. It has the advantages of high resistivity, thermal fatigue resistance, oxidation resistance and high temperature resistance. In addition, nickel-chromium alloys have good corrosion resistance, so they are widely used in the manufacturing industry, industrial electric furnaces and other heating elements.

This time, the outer circle of the industrial bushing was strengthened, and the nickel-chromium alloy coating was sprayed on the surface by the supersonic spraying process. In order to ensure the quality of the coating, when spraying, pay attention to the change of the coating temperature to prevent the coating from cracking due to excessive temperature; in addition, pay close attention to the stability of the spray gun and various instruments during the spraying process, and detect the data changes in time. , thereby ensuring coating quality.

As a metal surface treatment technology, thermal spraying technology can impart special functional coatings to various mechanical products, especially key components of equipment, thereby improving the performance of the workpiece surface and saving costs. In addition, with the continuous emergence of new coating materials and new processes, thermal spraying technology has become more and more widely used not only in the preparation of functional coatings, but also in the fields of metal green remanufacturing and additive manufacturing.
