摘　　要：采用剥离法测定容器材料腐蚀层重量等一系列试验,并对其结果进行了总结分析.结果表明:在温度不高于620℃的情况下,作为容器材料碳化硅明显比316不锈钢的抗熔融铝硅合金液腐蚀性能优越,石墨容器不能盛装熔融铝硅合金.在经过240次的热循环测试后,碳化硅试样基本没有被腐蚀,抗腐蚀性能优越,可用于高温太阳能热发电蓄热系统中.A series of tests were conducted to study the weight metal corrosion of container materials used by dint of peeling for storing Al-Si alloy. The results show that the carborundum containers are better at preventing corrosion of Al-Si alloy than 316 stainless steel, and the plumbago containers can＇t be used for storing the Al-Si alloy, under below 620 ℃. After the 240 hot circle, the carborundum containers don＇t corrode, and are excellent in preventing corrosion of Al-Si alloy, so they can be used for depositing heat of the solar thermal power generation of high temperature.
