摘要
Q235钢因具有良好的塑性、韧性和焊接性能而被广泛应用于汽车、建筑、制造和航空航天等领域。但Q235钢在含有Cl^(-)的海洋或盐雾等环境下容易被腐蚀,因此还需对其进行耐腐蚀性能研究。本文使用浸渍法成功制备出表面含有氧化锆(ZrO_(2))和氯化铈(CeCl_(3))搪瓷涂层的Q235钢材料,以期改善Q235钢的耐碱性能。主要探究煅烧温度、煅烧时间、复合ZrO_(2)-CeCl_(3)颗粒含量与比例对Q235钢耐碱腐蚀性能影响。对具有表面搪瓷涂层的Q235钢进行电化学阻抗谱、极化曲线检测与分析、表面形貌表征及表面元素分析,结果表明其最佳的工艺条件如下:最佳添加量混合6wt%(ZrO_(2)∶CeCl_(3)=1∶1),浸渍时间40s,煅烧温度875℃,煅烧时间8min。
Q235 steel is widely used in fields such as automotive,construction,manufacturing,and aerospace due to its excellent plasticity,toughness and welding performance.However,Q235 steel is prone to corrosion in marine or salt spray environments containing Cl^(-),so further research on its corrosion resistance is needed.Q235 steel material with enamel coatings containing zirconia(ZrO_(2))and cerium chloride(CeCl_(3))on the surface were successfully prepared using impregnation method,in order to improve the alkali resistance of Q235 steel.The main focus was to investigate the effects of calcination temperature,calcination time,content and proportion of composite ZrO_(2)-CeCl_(3) particles on the alkali corrosion resistance of Q235 steel.Electrochemical impedance spectroscopy,polarization curve detection and analysis,surface morphology characterization and surface element analysis were performed on Q235 steel with surface enamel coating.The results showed that the optimal process conditions were as follows:the optimal addition amount was mixed with 6wt%(ZrO_(2)∶CeCl_(3)=1∶1),immersion time was 40 s,calcination temperature was 875℃,and calcination time was 8 min.
