Microstructural and wear characteristics of Ti6Al4V/5%TiB2 + 5%TiC composites with different sintering temperature fabricated through powder metallurgy route

Abstract

The purpose of this research is to investigate the microstructural behaviour and wear resistance behaviour of hybrid composites based on Ti6Al4V and reinforced with TiB2(5%) + TiC (5%) and produced using the powder metallurgy process at various sintering temperatures. A study was done on the dry sliding behaviour of the Ti6Al4V alloy and the powder metallurgy-fabricated Ti6Al4V/5%TiB2-5%TiC composite. A pin-on-disk wear tester is used to analyse the wear and friction behaviour of TMCs under several sliding circumstances. The outcome demonstrates that titanium alloy has a significant wear rate at superior sliding speeds. With the aid of SEM morphology, EDS analysis changes in microstructural parameters as well as the wear characteristics were examined. The investigation revealed that the addition of reinforcements TiB2 and TiC with high sintering temperatures augmented the wear characteristics of the Ti6Al4V matrix.
