An orthogonal designing method Was used to optimize processing parameters of rare earth (RE) modified chromizing on P110 oil casing tube steel(P110 steel).The results show that the chromizing coating is available based on each processing parameter,the coating is uniform,continuous and compact.Taking the compositional thickness (w_(Cr)≥12%) as an evaluating indicator,the optimal process parameters are obtained as follows:chromizing temperature 1000℃,holding time 8h,and activator composition 3wt%,RE addition ratio 7wt%.
