| Abstract: | Reducing the low stress abrasive wear of materials has
emerged as a major challenge for researches conducted in the field of
engineering for sometime. In this direction, efforts are made for development
of prediction model for abrasive wear rate of medium carbon steel like SAE-6150
based on the influencing factors for precise prediction of wear rate and
selection of appropriate levels of factors. SAE-6150 steel is tested using dry
sand abrasion test rig after heat-treatment (annealing, intercritically
annealing and quenched and tempered) and shot peening (ranging 0.17- 0.47 A at
an interval of 0.1 A). The hardness and abrasive wear resistance
of as-received and annealed steel (ferrito pearlitic structure) are
significantly lower in comparison to inercritically annealed
(ferrito-martensitic structure) as well as quenched and tempered (tempered
martensitic structure) irrespective of peening intensity. The peening intensity
reduces the wear rate, if limited to a critical value of 0.17 A. The functional
relationship between wear rate and the factors influencing it is found
statistically significant and can be used for prediction of abrasive wear at a
given level of factors. |
