Wider application only gas law and salt bath method. Gas carbonitriding medium is a mixture of gas carburizing and nitriding agent, agent , for example, drops of kerosene ( or ethanol , acetone ) , ammonia ; endothermic or exothermic gas Zhuojia enriched high carbon potential gas and ammonia ; triethanolamine urea dissolved in alcohol or continuous infusion. [C], [N] and the mechanism of atoms other carburizing, nitriding the same , there is penetration of between synthesis and degradation :
CO + NH3? HCN + H2O
CH4 + NH3? HCN +3 H2
2HCN? 2 [C] +2 [N] + H2
Carbonitriding and quenching , tempering the organization is martensite nitrogen , carbon and nitrogen compounds and residual austenite. 0.6 ~ 1.0mm deep intensity carbonitriding layer , wear resistance and deep carburizing layer 1.0 ~ 1.5mm fairly . To reduce the availability of carbon and nitrogen is lower than 870 ℃ deformation , such as permeation medium load gear instead of carburizing conducted 930 ℃.
With rare reminder infiltration ( carbon RE permeation ) and can partially replace shallow carburizing and carbonitriding Nitrocarburizing or Sulphonitrocarburizing , carbonitriding applications face a narrowing trend.
Su's heat treatment Co. Ltd. was founded in 1990, after decades of development, scale is continually expanding, is located in Shajing Town Baoan District Shenzhen City Bridge second industrial zone, covering an area of 3000 square meters, the main business is to take all the metal, alloy steel, beryllium copper, heat treatment of high speed steel, cryogenic treatment (-196 C), nitrogen gas, liquid nitrogen, QPQ salt bath production line, high-frequency quenching, blackening and carburizing, the surface of hard and stainless steel processing.
