Abstract

In this study, the tribological behavior of EN24 steel and oil hardened non-shrinking steel (OHNS) is investigated. Experimentation is performed using a pin-on-disc wear test setup. EN24 is used as pin material and OHNS as disc. Samples of pin are performed under wet sliding conditions at ambient temperatures. Sliding speed, load, and time are input parameters, while frictional force, friction coefficient and wear are the output parameters. Wear losses and worn-out surfaces are measured using an electronic balance and an optical microscope. By introducing oils between the pin and disc, lubricant enhances the system performance which is measured. Ferrography is used for figuring out how many and what kind of wear particles are in lubricating oil. Surface investigations were carried out using SEM and EDS to understand the friction and wear behavior. Taguchi L9 is used for the design of experiments, and ANOVA is used for optimization. Most significant parameter observed is load as compared to sliding velocity and time in terms of frictional force and friction coefficient. For wear, load and sliding speed are significant factors.
