Latest Patents
Sturel's latest patents revolve around innovative press hardening methods. One of his notable inventions includes a process that involves several key steps. The method begins with the provision of a steel sheet for heat treatment, which is precoated with a zinc- or aluminum-based pre-coating for anti-corrosion purposes. Following this, a hydrogen barrier pre-coating is deposited, with a thickness ranging from 10 to 550 nm. The process continues with batch annealing of the precoated steel sheet in an inert atmosphere to create a pre-alloyed steel sheet. Afterward, the pre-alloyed steel sheet is cut to obtain a blank, which undergoes thermal treatment to achieve a fully austenitic microstructure. The blank is then transferred into a press tool, where it is hot-formed to create a part, followed by cooling of the finished part.
