Duplex coatings on stainless steel American Iron and Steel Institute (AISI) 310 were prepared by a double process consisting of a plasma nitriding treatment and a multilayer ZrO2-3 mol % Y2O3 coating grown by chemical solution deposition. In this paper we investigate the interdiffusion phenomena between the elements and the deposited phases. The zirconia coating process over the nitrided steel initiated strong diffusion events. Hydrogen diffuses easily throughout the coating and acts as a reducing agent. The layer of zirconia works as a sieve, retaining nitrogen and allowing the passage of hydrogen. The contribution of this study show the interdiffusion at the interfaces of elements in samples subjected to treatments known as duplex coatings.
