Abstract

ABSTRACT Many different additives have been used to improve the mechanical properties of stainless steel (SS) matrix materials. However, few studies are using carbonaceous additives. Among them, hydrothermal carbons (HTC), produced from biomass with a very low production cost and without any harmful chemicals, have not yet been tried. In this study, SS-HTC composites were produced by powder metallurgy using HTC in three different ratios. The effects of HTC content in the metal matrix on the mechanical, tribological, and corrosion tests are compared and discussed. According to the results of these tests, the best results of approximately 22% hardness value, 8% ultimate compressive strength, and 5% wear resistance increase were obtained with low HTC (0.25 wt%) use.
