(MRE) against an aluminum plate. Herein, the MRE was manufactured, and a stick?slip tester was employed to evaluate the stick?slip performance of the MRE under different velocities and load conditions with and without a magnetic field. The fast Fourier transform (FFT) of the friction force of the stick?slip and the roughness of the aluminum plate surface were calculated to confirm the stick?slip phenomenon. After the tests, the wear surfaces were
observed to evaluate the wear properties of the MRE regarding the stick?slip. Results showed that the stick?slip was smaller at lower velocity. At higher velocity, the reduction of the stick?slip under a magnetic field was more clearly observed. Moreover, the wear reduced with reduced stick?slip under a magnetic field.
