Abstract

Effects of heat treatment on the high-stress abrasive wear response of 0.2% carbon steel have been investigated at varying applied loads, abrasive (SiC) sizes and sliding distances. The heat treatment involved intercritical annealing at three different temperatures between Ac-1 and Ac-3 followed by ice water quenching in order to produce a dual phase microstructure consisting of varying quantities of ferrite plus martensite. The wear rate increased monotonically with applied load irrespective of the heat treatment schedule. Further, the wear rate increased drastically when the abrasive size was increased from 15 to 27 mu m; a further increase in the abrasive size led to only a marginal increase in the wear rate. In general, the wear rate decreased with increasing sliding distance and attained a nearly stable value at longer sliding distances. Increasing intercritical annealing temperature resulted into higher martensite content, thereby leading to reduced wear rate. However, the extent of reduction in wear rate with martensite content has been found to change with the applied load and abrasive size. The present investigation clearly suggests that it is quite possible to attain desired combinations of bulk hardness and microstructure (ferrite plus martensite) that could greatly control abrasive wear properties in low carbon steel. The observed wear response of the samples has been explained on the basis of microconstituent-abrasive interaction during the course of abrasive action, degradation of the abrasive particles and the nature of various microconstituents, i.e. mechanical properties.
