Application of Inkjet Printing for Depositing Salt Prior to Atmospheric Corrosion Testing

This study examined the feasibility of using an unmodified office inkjet printer for the precise deposition of soluble salt particles on planar metal samples for atmospheric testing. The density of the salt loading achieved in printing solid swaths ranged from 10 to using aqueous 1 and 4 M NaCl solutions with 95% confidence intervals per print. Printing these solutions on a steel coupon produced particles with a multimodal size distribution and mean Feret diameters . An application of the method for studying the effect of loading density on the atmospheric corrosion of steel is described.
