采用超音速火焰喷涂法对物理探测仪器表面进行改性处理,研究了原始喷涂态和不同热处理态的喷涂涂层的耐磨性能和耐腐蚀性能。结果表明,经过热处理后的喷涂涂层的耐磨性能都有所提高,随着热处理温度的升高,耐磨性能有先降低而后升高的趋势,在热处理温度为900℃时取得最佳的耐磨性能;涂层的腐蚀电位从低至高依次为:1 100℃热处理态<700℃热处理态<原始喷涂态<900℃热处理态<500℃热处理态,热处理温度为500℃和900℃的喷涂涂层的耐腐蚀性能较好。 The surface of the physical detection instrument was modified by supersonic flame spraying, and the wear resistance and corrosion resistance of the sprayed coating in the original spraying state and in different heat treatment states were studied. The results show that the wear resistance of the sprayed coating after heat treatment has been improved. With the increase of the heat treatment temperature, the wear resistance of the sprayed coating decreases first and then increases. The best heat treatment temperature is 900 ℃ The corrosion potential of the coating from low to high is as follows: 1 100 ℃ heat treatment <700 ℃ heat treatment
