Abstract

The main objectives of this thesis are: (a) synthesize and characterize Ni-Ti3SiC2 composites (Chapter 2), (b) understand and compare the effect of other MAX phases like Cr2AlC, Ti3AlC2 and MoAlB on the mechanical and tribological behavior of Ni-matrix composites (Chapter 3), and (c) explore an alternative alloy to compare the tribological performance with Ni-Matrix composites (Chapter 4). This study shows that Ni-matrix composites can be fabricated by using a combination of cold pressing and subsequent hot pressing. All the composites were then studied by detailed microstructure investigations, mechanical, and tribological characterizations.
