中文摘要：

为解决分布在西部盐湖地区出现的煤矿矿区钢材腐蚀问题,结合煤矿矿区实际环境,采用实验、理论分析等方法研究了镁水泥混凝土中钢筋的腐蚀.采用CS350电化学工作站,研究镁水泥混凝土中钢筋的电化学腐蚀,结合SEM微观实验和EDS元素扫描结果,对镁水泥混凝土中裸露钢筋腐蚀状况进行描述.研究表明：美加力涂层钢筋状态良好,未出现腐蚀状态;锌美特涂层钢筋出现了低腐蚀现象;而裸露钢筋表面出现了严重腐蚀.钢筋涂层防腐蚀性美加力涂层较好,锌美特涂层次之;涂层钢筋虽然防腐效果不同,但对裸露钢筋的防腐蚀性能有明显有利影响.

英文摘要：

In order to solve reinforced corrosion on coal mine area in the salt lake of the west,in combination with the practical environment of coal mine area,experiment and theory analysis methods were used to study the reinforced corrosion in magnesium cement concrete. By CS350 electrochemical workstation,a study on the electrochemical corrosion of reinforced in magnesium cement concrete was carried out. Combined with the SEM and EDS,status of bare reinforced corrosion in magnesium cement concrete was described. Results showed that state of steel bar with MAGNI coating was better,and did not produce corrosion; steel bar with ZINTEK coating resulted in phenomena of low corrosion; the corrosion of bare steel bar on surface was serious. The order from high to low anticorrosion performance of the coating is from MAGNI to ZINTEK coating. Anticorrosive effects of coating on steel bar are in very different level,but the coating positively affects anticorrosion performance of the steel bar.
