摘要

In this study, both a short-time cutting and a friction welding tests were carried out to evaluate the properties of adhesion quantitatively between the titanium alloys such as Ti, Ti-6Al-4V, βC-Ti and the cemented carbide tool, K10. The bonding phenomenon in the friction welding was very similar to the adhesion phenomenon in cutting from the metallurgical point of view. βC-Ti alloy was easy to adhere on the tool comparing with Ti and Ti-6Al-4V alloys. Moreover, the reaction layer in which titanium and carbon were enrich, was observed at the interfaces between the alloys and the tool in the friction weld joint even if the friction time was only 0.4s. The morphologies of reaction layers were different among the alloys. It was concluded that the properties of adhesion depend on the reaction at the interface between titanium alloys and tools, and the morphology of the reaction layers. Furthermore, the adhesion phenomenon in cutting may be reproduced using the friction welding.
