The friction surface destruction mechanism in a magnetic field

The paper considers the mechanism of forming and developing brittle (quasi-coarse) cracks in a sample of ferromagnetic material in a magnetized state. It is shown that the external magnetic field affecting friction surfaces has the most significant effect on the wear process if the cracks open perpe...

Description
Summary:The paper considers the mechanism of forming and developing brittle (quasi-coarse) cracks in a sample of ferromagnetic material in a magnetized state. It is shown that the external magnetic field affecting friction surfaces has the most significant effect on the wear process if the cracks open perpendicular to the magnetization vector. The paper describes the criterion of spontaneous crack growth in brittle materials taking into account magnetostatic energy.
