Tiivistelmä

Abstract. Two types of press hardening experiments were carried out to investigate the behavior of ZnFe coated 22MnB5 steel in direct press hardening process. The coating properties were studied using variable process temperatures and times with a flat-die and a forming tool. Coatings were
analyzed with optical and scanning electron microscopes. The results indicated that steels that have low coating weights (40/40 and 50/50 g/m2) may be processed successfully with short dwell times. For high coating weights (70/70 and 80/80 g/m2) a significantly longer dwell time is needed. The behavior of ZnFe coating in hot press forming experiments was in line with literature and the
findings of the flat-die experiments. Thus, the feasibility of the experimental press hardening equipment was confirmed.
