Surface texture treatment can improve the wear properties of the materials. Laser processing technology is often used for the preparation of surface texture of various materials because of its advantages of high precision and high efficiency. With the development of electromagnetic technology, more friction pairs serve in magnetic field environment. In order to analyze the effect of applied magnetic field on the friction and wear of the dimple textured surface, the dimple texture is fabricated with laser on the surfaces of the 45^# steel specimens, and wearing experiments are carried out under two experimental conditions, such as normal and applied magnetic field. Coefficient of friction, lubricating oil viscosity and wear mass loss of the worn specimens are measured. Worn surfaces and wear debris are observed with microscope. The experimental results show that under oil-lubricated conditions, applied magnetic field reduces the coefficient of friction, wear mass loss and adhesive wear on laser textured surface. Applied magnetic field can improve the oil viscosity, the capacity of trapping wear debris of textured dimples and the carrying capacity of oil film, which can improve the tribological properties of the laser dimple textured surface.
