Microhardness and wear behaviour of surface modified Ti6Al4V/Zr-TiC metal matrix composite for advanced material.

This is an ABSTRACT ONLY. The definitive version is published in Journal of Optoelectronics and Advanced Materials, vol.14(11-12), pp 991-997Surface modification of titanium alloy (Ti-6Al-4V) was made using a Rofin Sinar 4 kW Nd: YAG laser. A laser multi-track 50% overlapping process was employed to produce Zr and Zr-TiC metal matrix composite (MMC) coatings on Ti6Al4V substrate. The beam diameter was set at 4 mm. The microstructures of fabricated composites consist of homogeneous distribution of TiC particles which were free of cracks with x-ray diffraction (XRD) analyses indicating formation of interstitial carbides. Multilayer cladding involved Ti6Al4V + (100%Zr) and Ti6Al4V + (Zr+TiC) MMCs fabricated with 10, 20, 30 and 40 %TiC. Multiple track deposited samples revealed microhardness improvement as high as 1048.7 HV for 60%Zr+40%TiC MMC and the least hardness displayed is 606.6 HV for 90%Zr+10%TiC MMC. The wear result showed that the developed MMCs have low wear rate as compared to the substrate.enLaser claddingMetal matrix compositesRapid solidificationInterstitial carbidesBiomedicalAlloysTitanium alloysArticlePopoola, A., Ochonogor, O., Abdulwahab, M., Pityana, S.
