摘　　要：为有效防止建筑结构钢锈蚀,对其进行锌-钙系磷化处理。为促进磷化反应进而提高锌-钙系磷化膜的形貌和耐蚀性,在磷化过程中引入超声波振动。研究超声波功率对磷化膜的形貌、膜重、成分和耐蚀性的影响。结果表明:超声波对磷化膜成分无显著影响,但随超声波功率从0提高到200 W,磷化膜形貌变化很大,表面粗糙度和膜重均先降后增,耐蚀性先明显提高后变差。当超声波功率为120 W时,磷化膜表面较平整致密,表面粗糙度最低,仅为0.28μm,膜重达最高值9.16 g/m^(2),且表现出良好的耐蚀性。说明适宜强度的超声波能改善磷化膜平整性和致密度,使膜重增加,耐蚀性明显改善,可有效防止建筑结构钢锈蚀。Zinc-calcium phosphating treatment was used to effectively prevent corrosion of construction structural steel. In order to improve the phosphating process conditions and the surface quality and performances of zinc-calcium phosphating film,the ultrasonic vibration was applied in the phosphating process to promote the phosphating reaction and hence improve the surface quality and performances of zinc-calcium phosphating film. The effect of ultrasonic power on the morphology,weight,composition and corrosion resistance of phosphating film was studied. The results show that ultrasonic wave has no significant effect on the component of phosphating film. However,increasing ultrasonic power from 0 to 200 W significantly change the morphology of phosphating film. Meanwhile,with the increase of ultrasonic power,the surface roughness and weight decrease first and then increased,while the corrosion resistance increases firstly but then decreases. When ultrasonic power is set at 120 W,the phosphating film is flat and dense,with a minimum surface roughness of 0.28 μm and a maximum weight of 9.16 g/m^(2) and exhibits superior corrosion resistance,indicating that optimum ultrasonic can improve the smoothness and compactness of phosphating film,increase the weight and improve the corrosion resistance obviously,and thus effectively prevent the corrosion of construction structural steel.
