一、前言本实验是继我所滴注式可控气氛渗碳之后进行的。目的是在基本稳定氮势的前提下,实现碳氮共渗的碳势自控,从而为确定共渗层的碳氮含量、稳定共渗工艺、提高共渗质量提供手段。经过反复地实验,基本上达到了这一预期的目标。氮势的稳定主要是通过固定渗氮介质的用量来实现的;碳势的控制则是根据对炉气中 I. Preface This experiment is carried out after carburizing my drip controllable atmosphere. The purpose is to realize the carbon potential control of carbonitriding under the condition of basically stable nitrogen potential, so as to provide a means for determining the carbon and nitrogen content of the common permeation layer, stabilizing the permeation process and improving the quality of the common osmosis. After repeated experiments, basically reached the expected goal. The stability of nitrogen potential is mainly achieved by the amount of fixed nitriding medium; the control of carbon potential is based on the furnace gas
