METHOD FOR PREVENTING DECARBURIZATION OF STEEL MATERIALS |
摘要 |
<p>A method for preventing decarburization of a steel material comprising applying a mixture of SiC powder and metallic Al powder on the steel material, then applying an oxidation inhibitor thereon, and heating the thus coated steel material, so as to give 30 to 500 g/m2 SiC on the steel material. The present method is particularly useful for preventing the lowering in strength of steel materials due to the surfacial decarburization.</p> |
