Modeling of Thermal Processes in Electrical Spark Alloying of Materials Using Few-Layer Graphene

Year: 2026

Type: article

Abstract: The paper considers an unsteady temperature field in a semi-infinite body with a pulsed heat source characteristic of electric spark alloying. An analytical solution of the heat conduction equation in cylindrical coordinates for an instantaneous point source is given. Numerical calculations have been performed for an uncoated aluminum substrate with a thin graphene layer. It is shown that graphene deposition with a thickness of 1–2 microns increases the local temperature by 27,2% and reduces the melting depth and radius of the heating zone. An experimental study of the effect of multilayer graphene on thermal processes and surface morphology during electric spark alloying of aluminum and D16T alloy has been carried out.
