Description
Summary:•The generation of a plastic deformation beneath a sliding surface is the principal source of tribo-magnetization.•The tribo-magnetization effect under lubrication and non-lubrication condition is analyzed.•A model of tribo-magnetization is built.•Distribution and variation of magnetic domains and metallographic structure of materials are investigated. In this paper, a friction apparatus was developed to explore the magnetization phenomenon of pure iron during the friction process. A series of sliding-friction tests were carried out to study the tribo-magnetization effect under lubrication and non-lubrication condition. Furthermore, the correlation between the distribution and variation of magnetic domains and the metallographic structure of the materials were analyzed. And a model of tribo-magnetization was built. The results showed that the tribo-magnetization phenomenon under non-lubricated conditions was more significant than that under lubricated conditions because of the interaction between two interfaces which affected the range and deformation degree of the area of influence beneath the sliding surface. It was found that the generation of plastic deformation beneath a sliding surface is the principal source of magnetization.
