Technical Field

Background

Metal nitriding or carburizing is a common metal modification method. Such as metal nitriding, and chemical heat treatment to make nitrogen atoms penetrate into the surface of workpiece in certain medium at certain temperature. The product after nitriding treatment has the characteristics of excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. And for example, carrying out carbonization treatment, namely placing the metal or the mixture of the metal powder and the carbon-containing powder in a reducing agent atmosphere, and carrying out high-temperature treatment to obtain a carburized surface or carbide powder. Nitriding or carbonizing is an important means of metal surface engineering, and has a remarkable effect on the regulation and control of the metal surface performance. For the nitride or carbide of the relevant metal, the corresponding material and the component thereof can be obtained by a powder metallurgy method. In general metal modification, carbides, nitrides, hydrides, oxides and the like can be added as second phase components, and the influence on the toughness and related auxiliary properties of the material is obvious. However, due to the various doping modes of the second phase, the grain size of the doped ceramic phase component has a great influence on the strengthening and toughening of the ceramic phase and the regulation and control of related performance, and the liquid-solid and solid-solid doping can not meet the target requirements except for the liquid-liquid doping mode. The realization of regulation and control of relevant components in the metal material through gas-liquid reaction becomes an important means.

However, in the conventional metal nitriding, carbonizing, oxidizing or reducing method through the gas-liquid reaction, it is generally necessary to introduce a corresponding gas into the molten metal or metal alloy, and to add a forced stirring method to promote the gas-liquid reaction.
