In-situ water layer thickness determination during accelerated corrosion testing
A collaboration of researchers at the University of Virginia, Sandia National Laboratories Albuquerque, and Tohoku University Japan have recently published a paper that outlines the design, construction, and validation for in-situ water layer thickness determination during accelerated corrosion testing. In this work the Henniker HPT-100 was used to remove hydrocarbon contamination from the surface within the sensor in order to give a uniform for water layer, thereby creating an experimental system geometry that is directly comparable to the modeled geometry thickness determination.
Many metallic structures are subject to corrosive conditions such as salt spray. A salt spray test is a method of checking the corrosion resistance of materials or coatings. The water layer (WL) formed on the surface of the material during salt spray plays a great part in the rate of corrosion of the material. The paper advances the understanding of measuring the WL during the salt spray test.
