Mineralizing of Siliconized Layer of Iron and Steel Treated in the Molten Magnesium Bath with Silicon Carbide Powder

Abstract

A molten magnesium bath can be used for siliconizing of iron specimens embedded in SiC powder by keeping for 3.6ks at 1123K, to obtain an Fe₃Si-SiC composite layer on the surface of the specimens, as reported previously¹⁾. Then, another composite layer made of Fe₃Si and other materials can be also obtained by setting an extra layer of the materials powder between SiC powder layer and the base iron, and then treating in the bath. In the present paper, many materials powders including ceramics, such as nitrides, carbides, oxides and two refractory metals, Mo and W, were used to mineralize the siliconized layer of iron, most of which, except some, have been composed successfuly.
