Research Progress of Influence of Applied Magnetic Field on Friction Wear and Corrosion Properties of Friction Pair Materials
With the increasingly complex electromagnetic environment of measurement and control equipment and mechanical equipment,more and more friction pair materials work and serve in the magnetic field environment.The influence of external magnetic field on the friction,wear and corrosion performance of friction pair materials is of great significance to guide the safe,reliable and long-life operation of magnetic field-related mechanical equipment.This paper systematically summarizes the mechanism of the effect of external magnetic field on the friction and wear properties of metal and polymer friction pair materials.This paper combs and analyzes the influence form and degree of magnetic field parameters such as magnetic field intensity,magnetic field direction and frequency on the friction and wear properties of metal and polymer friction pair materials,and sums up the essential reason why external magnetic field promotes or restrains the corrosion of friction pair materials in the process of corrosion.The effects of magnetic field intensity and magnetic field direction on the corrosion rate,polarization curve and corrosion product morphology of friction pair materials are compared and analyzed.The research progress of molecular dynamics simulation under magnetic field conditions is summarized,finally,the shortcomings of the existing research are put forward,and under the condition of external magnetic field,especially the research on the interaction between wear and corrosion of friction pair materials in water-wading environment is prospected.
