THE METHOD OF PARTIAL CARBONITRIDING PROCESS FOR CARBON STEEL PARTS

摘要

PURPOSE: A method of partial carbonitriding process for carbon steel parts is provided to prevent the deformation of a specimen and additional process by gradually cooling the temperature of the specimen. CONSTITUTION: A method of partial carbonitriding process for carbon steel parts comprises next steps. An enamel coating is performed on the specific part of a specimen which is cut to be exact dimension. An oxide protection film(3) is formed on the remainder of the enamel coated part. A nitrocarburizing process(5) is performed after peeling the enamel coated parts.
