The Gas Carbonitriding Controlled by Microcomputer with the Resistance Method

The principle of the gas C-N total potential controlled with the resistance method is analysed. The controlling instrument of the C-N total potential and the hardware composition, the functional characteristics, the software flow diagram, the mathematic model of the system of the gas carbonitriding controlled by microcomputer in the resistance method and the producing application are presented in detail. The results show that the technique is sueessful, and the automatic control of the gas carbonitriding process under condition of the low nitrogen potential can be realized. Thus the technique can greatly improve the quality of products, cut down the consumption of energy.
