Abstract
A Cr2O3 diffusion barrier was in-situ formed between Ni coating and 316L through electroplating a Ni(NiO) transition layer firstly and then annealing at 900 °C for 8 h in Ar. The obtained Cr2O3 is dense, continuously grown and well-bonded with 316L. The diffusion and corrosion resistance of Ni coating with and without Cr2O3 diffusion barrier were investigated. No visible outer diffusion of elements was found during the heat treatment at 750 °C for 150 h and the Ni coating with a Cr2O3 diffusion barrier can provide a good protection for 316L in molten (Li,Na,K)F.
