Titanium- and cobalt-base alloys are the most widely used orthopedic implant materials. As there are specific advantages and disadvantages with both of them, one approach to fabricate superior implants is to combine these two material systems. The current work examines the feasibility of depositing CoCrMo coatings on Ti substrates using Laser Engineered Net Shaping®. Studies show that deposition of CoCrMo coating on a Ti substrate is very challenging, cracking and delamination being the major observations. Several alternative strategies, which may lead to satisfactory coatings, are presented.
