The article presents a study on the implantation of silver titanium alloy VT6. It has been shown that ion implantation contributes to the creation of compressive stresses in the surface layer of the target, which makes it possible to increase the endurance indices of the processed alloy under alternating loads. Ultrasonic processing leads to the formation of a nanostructured layer on the surface of a VT6 alloy target. As a result of ultrasonic impact treatment, the structure of the surface layer undergoes significant changes.
The article considers the effect of ultrasonic exposure after the ion implantation of titanium alloys VT1-0 and VT6 silver on the thickness of the ion-leged layer, the distribution of silver by the thickness of this layer and the scalar density of dislocations in the subsurface layer. It has been established that for the alloy VT6 at the same parameters of the implantation regime there is a deeper penetration of silver ions compared to the alloy VT1-0. Directly under the ion-leged layer is formed a layer with an increased rocky density of dislocations. The ultrasonic treatment of the implanted layer on the alloys studied contributed to the deeper penetration of silver ions and the alignment of its concentration by the thickness of the surface layer of titanium alloys.
The results of the technical titanium VT1-00 wear resistance before and after ion implantation by silver with different grain size after intense plastic deformation are presented. It is shown that the increase in the grinding degree of the titanium VT1-00 original grain is accompanied by increase in the intensity of wear during friction. It is established that high-dose implantation of silver ions is effective to increase the wear resistance of large-grain structure titanium VT1-00. This is due to the formation on the friction surface of secondary structures containing fine-dispersed intermetaloids based on titanium and silver.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
