Purpose: The main goal of this study is to develop and obtain some competitive products, with high added value. In particular, the attention will be focused on the possibility to obtain a new class of Cobalt based alloy by Ti addition. Design/methodology/approach: Modification of the composition by Ti addition can increase the corrosion resistance, processing and at the same time can improve the alloy biocompatibility. Findings: Addition of these elements has a positive effect on the alloy hardness. Up to 6% of Ti or combining Ti and Zr as alloying elements there are no significant differences as hardness concerns. As corrosion resistance in a simulated oral cavity environment concerns, no significant release of metal ions was observed, the pH value and the weight loss fulfil the conditions required by the Standard ISO 10271/2011. However, the best behaviour was obtained employing CoCrMoTi6 alloy. Research limitations/implications: Based on the up to date achieved outcomes, it appears that a quite homogeneous and good mechanical properties have been obtained modifying the original alloy with 6% of Ti. The future research work will be oriented to get additional and detailed data on the biocompatibility of the alloy. Practical implications: The central issue is the valid transfer to dentistry application. Originality/value: The aim of the paper is to obtain a new class of Co based alloy by the modification of the original chemical composition.
