To study the effect of silicon additions on the boronized depth, hardness and wear of the boronized layer, an electro-boronizing on the substrate such as electrolytic iron, ferritic and austenitic stainless steel has been carried out at the current density of 0.5A/㎠ and in the temperature range of 800-1000℃ for 1-5 hours. the findings from the experiment are summarized as follows. 1) Increased boronize depth was obtained with increased addition of silicon. excess silicon addition, however, inhibited the buronizing due to the increased viscosity of electrolyte. 2) Deeper boronized layer was resulted with ferritic than austenitic stainless steel. the boronized depth of the both stainless steels, however, were only one-third that of the electrolytic iron. 3) Wear resistance of the substrates was improved markedly by boronizing, showing the best result in the ferritic followed by austenitic stain-less steel and electrolytic iron.
