Method and device for realizing rapid surface modification of cold spray coating by microwave irradiation

Abstract

The application discloses a method and device for realizing rapid surface modification of cold spraying coating by microwave irradiation, and comprises the following steps: covering a graphite sheet on the surface of the coating, and covering a wave-absorbing material on the outer surface of the graphite sheet; placing the coating, the graphite sheet and the wave-absorbing material in a ceramic fiber box; a through hole for measuring the internal temperature of the ceramic fiber box is arranged in the ceramic fiber box; placing the ceramic fiber box in a microwave oven device, and arranging a temperature measuring device in the microwave oven device; the temperature measuring device is opposite to the through hole to realize the measurement of the temperature in the cavity of the ceramic fiber box; the output power, the microwave frequency and the heating temperature of the microwave oven device are set; the switch of the microwave oven device is turned on to heat the ceramic fiber box placed in the microwave oven device; if the temperature collected by the temperature measuring device reaches the preset heating temperature during the heating process, the heating is stopped, and then the sample is cooled with the oven to realize the modification of the surface of the coating. The method realizes the surface modification by the microwave irradiation method, the process is simplified, the cost is reduced, and the mechanical property loss of the coating is small.
