| 摘 要： | 采用SHS反应火焰喷涂技术,把Al-CuO系铝热剂引入到喷涂材料中,在AZ91D表面成功制备了Al2O3基复相陶瓷涂层.试验结果表明,SHS反应热喷涂层抗热震性明显优于普通热喷涂层,热震次数可达40次左右,若辅以Ni-Al打底,喷后重熔工艺可使涂层热震到50次时仍完好无损;喷涂试样耐蚀性随着致密性的增大而提高,反应热喷涂层耐蚀性比基体提高36倍;Ni-Al打底,喷后重熔后可提高至基体的160倍:清漆封孔后几乎不发生腐蚀,耐蚀性最好.

| Abstract: | With utilizing SHS reaction flame spraying technology and introducing Al-CuO thermite to the spraying materials,Al2O3-based multiphase ceramic coatings on AZ91D are prepared.Results indicate that the thermal-shock resistance of reaction spraying coatings is better than that of common ones.Their thermal-shock times can reach to about 40 times.If backed with Ni-Al alloy and remelt after spraying,the coatings will still be in good shape after 50 times of thermal-shocks.The corrosion resistance of spraying samp... |
