Recent Research from Zhejiang University of Technology Highlight Findings in Engineering (Running-in Performance of 7075 Aluminum Alloy Strengthened By Burnishing Technology)

Article Description

A 2D ultrasonic burnishing technology was employed to strengthen 7075 aluminum alloy. The running-in experiments for original and burnished samples were implemented, and the running-in performance was explored qualitatively and quantitatively. The results show that the worn surface of an original sample exhibited the peelings, scratches, and abrasive particles, yet the wear form of a burnished sample was relatively single, mainly with scratches. The quantitative parameter “maximum distance between phase points d ” was calculated. During the friction and wear process, the d of friction coefficient signal displayed the variation of first decreasing and then stabilizing, which was consistent with the running-in and steady-state stages of the friction system. Compared with the original sample, the burnished sample had a less d , which indicated that the phase trajectory had a more convergence, and the friction system had a better stability. This study can guide surface strengthening and running-in performance analysis.
