摘要 采用等离子堆焊技术在Z2CN18-10核电用不锈钢表面堆焊Ni60合金,并研究Ni60合金堆焊层的组织结构、硬度和耐蚀性能。结果表明:堆焊层组织主要由γ-Ni、碳化物、硼化物以及γ-Ni和硼化物的共晶组成,堆焊层的底层、中间层和顶层位置各相体积分数不同,中间层菊花状组织最多。Ni60堆焊层硬度约为500HV,明显高于Z2CN18-10不锈钢基体,菊花状共晶组织有助于提高堆焊层硬度。Ni60在硼酸中的钝化能力明显高于海水,且与Z2CN18-10不锈钢的自腐蚀电位差较小,不易发生电偶腐蚀。在模拟海水中堆焊层中间层耐腐蚀性能优于堆焊层的底部和顶部,与基体的自腐蚀电位差较大,容易出现电偶腐蚀。

Abstract:The Ni60 overlay was deposited on Z2CN18-10 stainless steel substrate by plasma transferred arc (PTA) method, and the microstructure, hardness and corrosion resistance of Ni60 overlay were investigated. The results show that the overlay mainly consists of Ni-rich γ solid solution (γ-Ni), borides and carbides, and γ-Ni and borides eutectic structure. The overlay from the top to bottom shows different phase fractions, and the amount of chrysanthemum-like structure in the middle is large. The hardness of Ni60 overlay is around 500HV, which is higher than that of Z2CN18-10 stainless steel. The hardness increase is attributed to the chrysanthemum-like eutectic structure. In the borate, Ni60 exhibits higher passivation ability than that in seawater, and the corrosion potential of Ni60 alloy is similar to Z2CN18-10 stainless steel. In simulated seawater, the corrosion resistance of overlay in the middle is more superior than that in the bottom and top. Due to the large difference of corrosion potential in seawater, the galvanic corrosion is prone to occur between Ni60 overlay and Z2CN18-10 stainless steel.
