The purpose of this scientific paper is to follow the influence of thermal galvanizing, as a technological process on the quality of the galvanized surface. The galvanizing technology used and studied involves at the end of the process, the removal of excess zinc from the surface by centrifugation. The zinc layer will be lower than that of simple immersion galvanizing. The measurements were performed following the roughness of the machined surface on a five-Section specimen – each Section being processed with a different cutting regime. The results were analyzed after each operation. The first measurements were made after the turning operation, followed by measurements made after pickling and fluxing and then after thermal galvanizing. Based on the results obtained, the aim was to set up a range of best roughness at which the galvanized part should have a commercial appearance and be made with a cost-effective cutting regime in terms of costs.
