Abstract

Superalloys are metallic systems commonly used in components for aerospace and energy generation applications. In this paper, results of an investigation developed to analyze the effect of heat treatment on the wear behaviour of a Haynes 282® superalloy under sliding, non-lubricated conditions are presented. Room temperature pin-on-roll wear tests were undertaken at a constant load and for a fixed sliding distance of 7.5 km. It was found that the wear rate of the alloys was greater for the heat treated specimens compared to the specimens that were tested in a cast and forged condition. Inspection of the alloys in both metallurgical conditions suggests that the wear phenomenon was characterized mostly by severe plastic deformation of the alloy matrix at both, surface and subsurface regions by the well-known mechanism of ploughing. The test specimens also experienced the formation of a tribofilm whose characteristics were different for each test condition. The formation of tribofilms had also a considerable influence on the wear behaviour of the systems studied because they were also present on the surface of the counter rolls being this phenomenon an additional wear mechanism experienced by the tribosystems studied.
