摘要

采用电火花沉积技术在CrNi3MoVA表面制备了Cr和Cr - 10ta涂层，并对其耐蚀性进行了评价。结果表明，与CrNi3MoVA涂层相比，Cr-10Ta涂层的腐蚀电流密度（Icorr）降低了76%，腐蚀电位（Ecorr）提高了13%。Cr涂层可使Icorr降低46%，Ecorr升高8%。Cr和Cr - 10ta涂层的电荷转移电阻分别是CrNi3MoVA涂层的1.5倍和6.4倍。Cr - 10ta涂层的耐蚀性优于Cr涂层，Cr涂层具有局部腐蚀。

Ta Influence on Corrosion Resistance of Cr Coatings via Electrospark Deposition

Cr and Cr–10Ta coatings were prepared on CrNi3MoVA using electrospark deposition technology and evaluated for their corrosion resistance. The findings indicated that the Cr–10Ta coating demonstrated a 76% decrease in corrosion current density (I_corr) and a 13% increase in corrosion potential (E_corr) compared to the CrNi3MoVA. The Cr coating exhibited a 46% reduction in I_corr and an 8% elevation in E_corr. The charge transfer resistances of the Cr and Cr–10Ta coatings were 1.5 and 6.4 times higher than that of the CrNi3MoVA. The Cr–10Ta coating demonstrated better corrosion resistance than the Cr coating for the latter had a localized corrosion.
