Effects of Electroless Parameters on Fe Content in Ni-P-Fe₂O₃ Composite Coatings on Stainless Steel

Abstract:

Ferritic stainless steels have been widely used as solid oxide fuel cells (SOFCs) metallic interconnects. However, the evaporation of Cr₂O₃ might migrate to and poison the cathode, leading to degradation of the cell performance. In this work, Ni-P-Fe₂O₃ composite coating was deposited on the ferritic stainless steel by means of a cost-effective technique of electroless method. They are expected to be converted into (Ni,Fe)₃O₄ spinel with a high electrical conductivity and CTE match with stainless steel, which can hinder the evaporation of Cr₂O₃ formed on steel substrate exposed to the cathode environment of the SOFC. The effects of Fe₂O₃ contents, pH and temperature of solution on the deposition rate and Fe contents of the Ni-P- Fe2O3 composite coatings were investigated. The results indicated that the effects of Fe₂O₃ contents and pH of solution on deposition rate was not obvious and the deposition rate increased with increasing temperature. They had obvious influences on the Fe contents in the coating. The suitable deposition conditions are as below: the Fe₂O₃ content , pH and temperature was 16 g/L, 8.5 and 65 , respectively. The coatings consisted of Ni, Fe , P and O.
