摘要
工业纯锆R60702是一种稀有金属,具有良好的焊接性和抗腐蚀性,其熔点、硬度和强度均很高。分析了R60702在经过管板角接后,焊缝的元素成分和耐腐蚀性能,通过极化曲线和交流阻抗图分别表征了锆材焊缝在30℃和70℃的耐蚀性。
Industrial pure zirconium R60702 is a rare metal, has good weld ability and corrosion resistance, and its melting point, hardness and strength are very high. In this paper, element composition and corrosion resistance of zirconium R60702 weld seam after tube plate angle joint were analyzed. Through the polarization curve and AC impedance graph respectively characterize the corrosion resistance of the zirconium weld joint at 30℃and 70℃.
