摘 要：<正> The electrolytic coatings of boron and RE-boron on medium carbon steel are carried out in molten salt mix-tures respectively.The brittleness of both coatings has been measured by using sound-emission with the methodof three point bending.Results show that the brittleness of electrolytic boronization coating can be obviously de-creased by addition of RE elements.Meanwhile,the shape of crack and the solid solubility of RE in boride andα-Fe phase are determined,and the effect of RE on the lattice constant of Fe2B is discussed.From these experi-ments,the authors explain the cause of the brittleness decreasing of electrolytic boronization coating.
