Abstract

Accelerated cut-edge corrosion performance of commercialized full waterborne coating systems containing enviro-friendly corrosion inhibitors was studied on 55 wt% Al, 44 wt% Zn and 1 wt% Si galvanized steel in 5 wt% NaCl solution at ambient temperature via the Scanning Vibrating Electrode Technique...
