    Abstract: A carbon hardened surface is produced in a metal workpiece without forming carbide precipitates by carburizing the workpiece at high temperature carburization conditions, rapidly quenching the workpiece, and then carburizing the workpiece under low temperature carburization conditions.

    Abstract translation: 通过在高温渗碳条件下渗碳工件,快速淬火工件,然后在低温渗碳条件下对工件进行渗碳,在金属工件中制造碳化表面,而不形成碳化物析出物。

    Abstract: 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.

    Abstract translation: 使用乙炔作为渗碳物质的不锈钢的低温渗碳在氢气或其他伴生气体的存在下在软真空条件下进行。 结果,几乎完全消除了在低温渗碳期间通常发生的烟灰和不期望的热氧化膜的形成。
