Abstract

The erosion-wear behaviour of spark plasma-sintered austenitic stainless steels matrix composite was investigated under high temperature conditions. Erosion-wear behaviour of the composites was conducted at a constant velocity of 18 m/s and impinging angle of 90° at different temperatures of 25, 400 and 600 °C. Hard abrasive alumina particles with particle size of 40 µm were used as erodent. After SPS, relative density of spark plasma-sintered samples decreased with increasing TiN content. Furthermore, the results show a reduction in material loss with increased hardness. However, there was a significant increase in material wastage as temperature increases. Microstructures of the eroded samples indicate that the erosion damage occurs mainly by plastic deformation and brittle fracture. Large fragments in the form of wear debris, pitting, ploughing with slip on the side, misplaced material and a few grooves are observed as well on the SEM images.
