Abstract Scope |
Metallic surfaces exposed to atmospheric conditions can be affected by corrosion. The extent and rate of corrosion is determined by multiple factors and the Finite Element Method (FEM) is a computational technique capable of providing accurate estimates of corrosion by numerically solving the complex differential equations that describe this phenomena. However, the iterative nature of FEM causes for FEM to be ill-equipped for an efficient exploration of the design space to identify factors that deter corrosion, despite its accuracy. We introduce a machine learning based model capable of providing accurate predictions of corrosion with significant computational savings. This work leverages decision trees to provide an accurate estimate of current given different values of temperature, water layer thickness, molarity of the solution, and the length of the cathode for a galvanic couple of aluminum and stainless steel. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. SAND2023-05762A |
