离子轰击化学热处理具有省电、省气、速度快、无公害及质量可控等优点,其中离子渗氮已成功地应用于生产。但对于处理温度较高的离子碳氮共渗,由于技术上的原因,目前还停留在实验室阶段,国外也未见生产应用。国内虽有个别单位在生产上试用,但如工艺参数对渗层组织结构及性能的影响规律,如何确定最佳工艺以及更为突出的温度不均匀等问题,尚需进行大量研究。本文针对上述问题,就高 Ion bombardment chemical heat treatment has the advantages of power saving, gas saving, speed, pollution-free and quality control, ion nitriding has been successfully applied to the production. However, for the treatment of ionized carbonitriding with higher temperature, due to technical reasons, it still stays in the laboratory stage at present, and there is no production application abroad. Although there are some domestic units in the trial production, but as the process parameters on the structure and properties of the infiltration layer structure, and how to determine the best technology and more prominent problems such as uneven temperature, the need for a large number of studies. This article addresses the above issues, high
