Determination of the optimum conditions for salt bath ferritic Nitrocarburizing process of AISI 1018 Steel using ANOVA method.

Jagdeep Sharma, Balwinder Singh Sidhu, Rajesh Gupta


Industrial modern machinery components such as gears, bolts and shafts are always subjected to continuous frictional wear. From decades' surface treatments are performed to enhance the tribological properties of these components, however use of toxic cyanide salts in the techniques like Nitrocarburizing is a threat to environment. Therefore, another non-toxic surface modification process Sursulf Nitrocarburizing is investigated on AISI 1018 low carbon steel and results were analyzed and optimized using ANOVA technique accordingly. It has been observed that with the increase in Nitrocarburizing time and Nitrocarburizing temperature a significant enhancement in tribological properties like wear and hardness of the work material has been found.


Environment friendly surface modification technique, Sursulf Nitrocarburizing, salt bath Nitrocarburizing.
