【Abstract】 Researches on Boronizing and B-Mn Permeating in some foreign countries have been reviewed in this paper. Microstructures of 45 steel and T12 steel after B-Mn Permeation in different amount of manganese are studied here. It is shown from the experiments that as the Mn content in the penetrant increases, the permeation region is gettion thinner and thinner, and its hardness decreases too. when the amount of Mn in the penetrant is fairly high,austenite will exist in the permeation region.更多还原
