In this study, the Nitride and WCC coated AISI 4140 alloy steel to experimentally tested and analyzed to improve tribological. Selected AISI 4140 steel is optimized for tribological test settings using the grey relational analysis method. Taguchi method is implemented for experimental design which gives nine experimental runs based on orthogonal array. Coefficient of friction (COF) and wear is measured for nine different test on Pin on disc Tribometer. The optimal setting for Nitride and WCC coated AISI 4140 alloy steel and confirmation test is performed which gives clear indication of optimum operating condition for AISI 4140 steel.
