Abstract: The Present study deals with to analyze the Tribological wear behaviour of dual-phase steels containing different weight percentages of carbon from 0.2 to 0.6, volumetric wear rates have been investigated. All the specimens were quenched at 723oC to obtain specimens containing about 25, 50 and 75% martensite for weight percentage of carbon from 0.2, 0.4 and 0.6 respectively. wear tests have been conducted on dual-phase steels using a pin-on-disc wear testing machine under the normal load of 9.81, 29.43 and 49.05 N, sliding speeds of 1, 3 and 5 m/s at room temperature for a fixed sliding distance of 20,000 meters. Weight loss has been measured for each specimen at the end of the experiment. Using the L9 orthogonal array all the experiments was conducted. Volumetric wear rate has been calculated on the basis of volume loss after converting weight loss into volume loss by considering the density of the material. The analysis of volumetric wear rate, with respect to the sliding speeds and normal load have been explained by using taguchi technique and analysis of variance. Wear properties have been found to improve with the increase in martensite volume fraction in dual-phase steels. Among the investigated specimens, the critical parameters were found to be 0.4% of carbon content, 29.43N of normal load and 5 m/s of sliding speed.
