Titanium and its alloys have low density, superior resistance to corrosion, and high specific strength, also found extensive use in the aerospace, petrochemical, biomedical, and many other industries. Because metastable β-titanium alloys with b stabilizing elements like Nb and Zr provide a great mix of low modulus and high strength, they are particularly desirable as implant materials. Titanium diboride TiB2, is a very hard ceramic with superior wear resistance, oxidation stability, and heat conductivity. The purpose of this research is to estimate the influence of TiB2 at several percentages (0.1, 0.2, 0.3, and 0.4%wt.) on the Ti2448 alloy fabricated by powder metallurgy, macrostructures, and mechanical characteristics of powder-metallurgically produced Ti-24Nb-4Zr-8Sn-TiB2 composites. According to the experimental findings, the hardness rises as the percentage of TiB2 grows, reaching 166 HB at 0.4%wt. addition, while the wet wear rate falls as the TiB2 content increases, reaching 7.09×10-5g/cm.
