In cold forming, die materials are subjected to severe wear because of high contact temperature and pressure. D2 steel is used as die material for cold forming applications. However, its friction and wear properties have not been studied fully under high stress and high temperature conditions. Friction and wear behavior of D2 steel against AISI 52100 and Alumina have been studied under dry sliding conditions in temperature range of RT – 150°C, using ball-on-disc universal tribometer. For sliding distance test the wear rate of D2 with AISI 52100 is less than the Alumina for entire range at 150°C. The wear volume of D2 steel increases with the increase in sliding distance from 200 m to 1000 m against AISI 52100 and Alumina. For D2 steel, highest coefficient of friction (μ) 0.751 and 0.754 against AISI 52100 and Alumina was obtained at 5 N, whereas minimum μ of 0.32 and 0.43 against AISI 52100 and Alumina was obtained at 25 N, these tests were carried out at 150°C. For temperature test, highest coefficient of friction (μ) of 0.92 and 0.7671 against AISI 52100 and Alumina was obtained at 50°C, whereas minimum μ of 0.77 and 0.52 against AISI 52100 and Alumina was obtained at RT. Optical microscopy, SEM, EDXA and 3D profilometery have been used to understand the friction and wear mechanism of tribopair. From these observations it is concluded that wear of D2 steel is minimum for particular range of load and temperature. The results obtained are useful for designers and engineers working in the field of cold forming.
