This review describes previous studies undertaken in the field of titanium alloy based human body implants, and the potential to be fabricated using one of the most disruptive technologies, i.e., additive manufacturing. Laser cladding is an emerging additive manufacturing technique and can produce implant materials directly from premixed alloy powders. Human body implants are specific materials that have to be manufactured according to the patient’s requirements and titanium alloys have been the prime choice for patient-specific implants. However, stress shielding (a mechanical incompatibility) occurs in titanium alloys due to which a follow-up revision surgery needs to be performed. Therefore, numerous studies are being undertaken by researchers to find suitable alternatives to existing alloys. b-titanium alloys have proven to be more useful due to their stable microstructural and mechanical properties. In this article, useful fundamentals of laser cladding along with potential applications are discussed. An in-depth review of laser cladded titanium alloys, their in-vitro corrosion and wear behaviour is presented and useful alternatives are suggested.
