Abstract

This research examines the effect of salt bath, and nitriding processes on hot forming tool steel. The chosen steel is BÖHLER W350 ISOBLOCK hot forming tool steel, which is widely used in the industry for pressure casting. After surface treatment, some samples were exposed to cyclic heat and corrosion effects in a molten aluminium medium, thus simulating the conditions experienced during pressure casting. Microhardness measurements were performed on the samples treated with different procedures. The results were compared using a scanning electron microscope and energy-dispersive X-ray spectrometry.
