Title: New Accelerated Corrosion Test for Zinc-coated Steel Sheets used in Electrical Appliances
Abstract:Based on the actual corrosion behavior of electrical appliances and inadequacies of the conventional accelerated corrosion tests, which are the salt spray test (SST) and combined cyclic corrosion test...Based on the actual corrosion behavior of electrical appliances and inadequacies of the conventional accelerated corrosion tests, which are the salt spray test (SST) and combined cyclic corrosion test (JASO M609-91), a new accelerated corrosion test for electrical appliances, (ACTE: Accelerated Corrosion Test for Electrical Appliances) was developed. A good correlation between ACTE and corrosion in actual environments was demonstrated. ACTE consists of a salt deposition process and cyclic wet/dry process. As distinctive features of ACTE, the test conditions simulate actual environments (use of artificial seawater, constant absolute humidity), and it is possible to estimate the corrosion life of materials in a wide range of use environments by obtaining dependency data on the main corrosion factors (amount of deposited sea salt, etc.) by varying the test conditions. ACTE makes it possible to appropriately evaluate the corrosion resistance of zinc-coated steel sheets with chromate-free coatings.Read More
