摘要：
Low temperature carburization of stainless steel using acetylene as the carburizing specie is carried out under soft vacuum conditions in the presence of hydrogen or other companion gas. As a result, formation of soot and the undesirable thermal oxide film that normally occurs during low temperature carburization is eliminated virtually completely.
