针对耐磨构件，尤其是齿轮等机械构件质量低和生产成本高的现状，提出变温低压渗碳新工艺。经过实验研究，表明变温低压渗碳技术比一般渗碳技术具有节能、渗速快、质量好、生产效率高和低环境污染等方面的优越性。循环次数的增加是不会降低渗碳速度的。 Aimed at the low quality and high production costs of wear-resistant components, especially gears and other mechanical components, a new temperature-controlled and low-pressure carburizing process is proposed. After experimental studies, it shows that the variable temperature low pressure carburizing technology has the advantages of energy saving, fast permeation rate, good quality, high production efficiency and low environmental pollution than the ordinary carburizing technology. The increase in the number of cycles does not reduce the carburizing rate.
