Abstract: The friction induced magnetization (FIM) behavior of a magnetic conductive brake pair consisting of magnetic organic friction material and HT250 brake disc was studied on a simulated test bench of disc brake. The influencing laws and mechanisms of initial braking speed and braking pressure on the FIM were investigated and discussed by experiments. The results show that by increasing initial braking speed a significant rise of temperature on the friction surface was observed and thermal demagnetization effect reduced the magnetic induction intensity. The initial braking speed might be a major factor for reduced FIM. However, the surface temperature increased slightly with the increasing braking pressure. And the degree of wear damage increased gradually, which resulted in a significant increase of amount of elements iron and nickel on the worn surface. The magnetic induction intensity was then increased, indicating that the braking pressure may be of great significance for enhanced FIM. It is believed that the research can provide not only important theoretical basement for developing of magnetic field controlled braking technology, but also valuable reference for investigation of surface FIM in related macro machinery and micro-nano systems.
