A comprehensive experimental platform was developed, integrating a particle emission system, a wall movement system, high-speed imaging, and ultra-depth-of-field microscopic measurements, enabling precise control and characterization of particle impact velocity, angle, and wall movement parameters. and micro-measurements provided geometric details of the wear pits. Experimental results indicate that the increase in relative speed caused by reverse motion leads to the highest wear rate, while forward motion, due to partial energy cancellation, results in the lowest wear. The wall motion speed is strongly positively correlated with the wear rate. The effect of the impact angle on wear follows a nonlinear trend, stabilizing beyond the supercritical angle. This study deepens the understanding of particle-wall interactions under dynamic conditions and provides reliable experimental data for the wear-resistant design and life prediction of relevant industrial equipment.
