Abstract

A hybrid Ti-6A1-4V based metal matrix composites characterized of martensitic structure was formed using three hoper system. Different volume percentages used were as follows: 3.0 vol. % of Ti-6A1-4V, 3.2 vol. % of T1-6A1-4V and 3.4 vol. % of Ti-6AI-4V respectively while an equal amount of BN and B₄C mixed with the Ti-6A1-4V powder particle was fed through the hoper systems at a constant laser power 2000 W and scanning speed of 1.0 m/s. The influence of rapid cooling and varied powder particle at constant coating temperature on the surface morphology and hardness property of Ti-6A1-4V/B4C/BN alloy systems was however investigated. The hardness result of experimental showed a general improvement. Further result showed that the Ti-6A1-4V/B4C/BN system fabricated at 3.0 Ti Vol. percent had a hardness improvement as high as 986.9 HV_0.5 compared to the as receive Ti-6A1-4V substrate Hardness value of about 357.3 HV_0.5.3.2 Ti Vol. percent systems recorded a hardness value of 723.4 HV_0.5 and 3.2 Ti Vol. percent system recorded a hardness value of 609.6 HV_0.5. Optical microscope (OM) Scanning electron microscope (SEM) was also carried out for microstructural evaluation and Energy Dispersive Spectroscopy (EDS) to confirm the elemental composition of coating when necessary.
