摘要
分析了氮势控制的基本原理,通过测定和控制氨气流量来控制氨分解率,从而实现气体渗氮的氮势控制。给出了以PIC单片机为核心的气体渗氮中氮势控制自动控制仪硬件及软件设计的原理。测定了不同温度下传感器的输出电势、氨气流量与氨分解率之间的对应关系,并以此为依据制定工艺,对40Cr、35CrMo、1Cr13不锈钢试样进行气体渗氮自动控制,取得了较好的效果。
This paper an alyzed the basic principle of nitrogen power automatic control.To realize nitro gen power automatic control of gas nitration,ammonia resolvability can be contr olled by testing and controlling ammonia rate of flow.It also introduced the pr inciple of hardware and software design of the nitrogen power automatic control meter based on PIC micro-controller.By determining the relation between the s enor output electrical power and the ammonia rate of flow,formulating the nitr ation technology,we carried on the automatic control of gas nitration to40Cr 、35CrMo 、1Cr13stainless steel samples and made the better effect.
