Abstract
A new approach was introduced by combining laser powder bed fusion and hot isostatic pressing processes to create a Ti6Al4V-Ti composite alloy structured similar to nacre, merging Ti6Al4V with pure Ti. Titanium alloys are known to be sensitive to fluoride ions commonly found in dental products like rinses, toothpaste, and mouthwashes, impacting their corrosion resistance. Therefore, the aim of this research is to investigate how fluoride ions affect the corrosion characteristics of the Ti6Al4V-Ti composite and to evaluate the unique dissolution behaviors observed in the Ti6Al4V and pure Ti zones. The findings from electrochemical tests reveal that adding fluoride ions decreases the composite's corrosion resistance, yet fluoride concentrations of 0.01 and 0.05 M still exhibit passive behavior. However, at a fluoride concentration of 0.1 M, there is a significant degradation of the passive film, presenting a porous structure. Additionally, the observation from atomic force microscope demonstrated Ti6Al4V zone shows a preference for dissolution compared to the Ti zone, particularly evident at fluoride ion concentrations of 0.1 M. This study is expected to provide valuable insights to deepen the understanding of Ti6Al4V-Ti composites' suitability for dental applications.
