Summary: tantalum has wide applications as a bio material for human implants. boronizing of tantalum was carried out by powder pack method for different temperatures and time regimes.the thickness of the coating increased exponentially with temperature and parabolically with time.the presence of a uniform boride layer was confirmed by XRD.the surface morphology was analyzed and the microhardness measurments were done
