Query: Machining of Spherical Component Fabricated by Selected Laser Melting,
  Part II: Application of Ti in Biomedical   Ti and Ti-Based alloys have unique properties such as high strength, low
density and excellent corrosion resistance. These properties are essential for
the manufacture of lightweight and high strength components for biomedical
applications. In this paper, Ti properties such as metallurgy, mechanical
properties, surface modification, corrosion resistance, biocompatibility and
osseointegration in biomedical applications have been discussed. This paper
also analyses the advantages and disadvantages of various Ti manufacturing
processes for biomedical applications such as casting, powder metallurgy, cold
and hot working, machining, laser engineering net shaping, superplastic
forming, forging and ring rolling. The contributions of this research are
twofold, firstly scrutinizing the behaviour of Ti and Ti-Based alloys in-vivo
and in-vitro experiments in biomedical applications to determine the factors
leading to failure, and secondly strategies to achieve desired properties
essential to improving the quality of patient outcomes after receiving surgical
implants. Future research will be directed toward manufacturing of Ti for
medical applications by improving the production process, for example using
optimal design approaches in additive manufacturing and investigating alloys
containing other materials in order to obtain better medical and mechanical
characteristics.
