This paper reports the results of a series of compound wear experiments conducted using heat treated 1042 steel sliding against A2 tool steel under normal atmospheric environmental conditions for severe wear. Compound wear takes place where there is sliding and impact motion occurring simultaneously. The influential variables that are considered in the statistically designed experiment are: normal impact load, frequency, and the rotational sliding speed with lubrication as an extra class variable. Experiments were conducted using a multi-purpose wear testing facility. The frictional force was determined from strain gauges. LabView™ software was used to monitor and store the continuous load and strain signals for further analysis. Using these data an empirical relationship modeling wear has been determined.
