Abstract

Corrosion pervades in every field of the public domain, with a particularly pronounced impact in the marine environment. Laser descaling technology, heralded as an environmentally conscious method, is progressively gaining prominence within the maritime domain. The associated theories and procedures have incrementally assumed a central role in scholarly investigations. This study meticulously delves into the evolution of rust on the surface of the Q235 steel. By employing a salt spray test, we study the growth dynamics of the rust layer on the Q235 steel. The inquiry encompasses an examination of the growth rates in both transverse and longitudinal orientations, coupled with an analysis of the composition of rust layers. Leveraging ANSYS simulation software and thermodynamic analysis, we delve into the parameters governing the descaling process, serving as a crucial reference for subsequent experimental descaling endeavors. The results stand to offer valuable insights into the advancement of descaling technology.
