摘要:
为减轻45钢法兰表面锈蚀，对法兰进行锌-锰系磷化处理，并在磷化过程中辅助超声波震荡。表征了磷化处理后法兰的宏观形貌和微观形貌，分析了磷化膜表面元素组成，并测试了未经磷化处理法兰和磷化处理后法兰的耐腐蚀性能。结果表明：磷化处理后法兰呈均匀一致的深灰色，表面致密，晶粒呈棒状和条状。磷化膜的厚度约13.4 μm，元素组成主要为Zn、P、O和Mn，各元素在磷化膜中呈较均匀分布。磷化处理后法兰的耐腐蚀性能明显优于未经磷化处理法兰，盐雾试验48 h后，磷化处理后法兰的锈蚀面积较小，另外其腐蚀电位、腐蚀电流密度和低频区的阻抗值等指标也较好。
Abstract:
The 45 steel flange was treated by zinc-manganese phosphating assisted with ultrasonic vibration in order to reduce surface corrosion. The macro-morphology and micro-morphology of the flange after phosphating treatment were characterized, the elemental composition of the phosphating film was analyzed, and the corrosion resistance of the flange without phosphating treatment and the flange after phosphating treatment was tested. The results showed that the flange after phosphating treatment has a uniform appearance of dark gray, with dense surface structure and rod and strip grains. The phosphating film with a thickness of 13.4 μm was mainly composed of Zn, P, O and Mn, and each elements were evenly distributed in the phosphating film. The corrosion resistance of the flange after phosphating treatment was obviously better than that of the flange without phosphating treatment. After 48 h salt spray test, the corrosion area of the flange after phosphating treatment was smaller. In addition, the corrosion potential, corrosion current density and impedance value in the low-frequency zone of the flange after phosphating treatment were also better than that of the flange without phosphating treatment.
