Abstract [en]

During the past years, large efforts have been made, to analyze and evaluate the surface quality of dies manufactured in nodular iron (GGG70L). The variation of quality in respect of wear resistance hardenability and micro cracks are the main issues. It results in bad surface quality on the formed parts (scratches) which gives break down in the production and increases the maintenance (repolishing of tool surface). The spread in wear resistance depends on that the parameters for a functional working surface combined with and the lubrication is not clarified and thus not been able to be specifie . The main parameters for a functional working surface are among other things the amount of nodules (n), size, shape (style), how the exit side (in draw direction) of the nodule crater looks like. Different qualities in respect to size, amount and shape of the nodules in a nodular iron have been tested against uncoated sheet material (H300LA, t=1.5mm) in semi-industrial test equipment (OSAS U-bend). The surface conditions of the nodular iron are laser or induction surface hardened. The result in this investigation shows that nodular iron (GGG70L) with high nodule count and small nodule size in the working surface gives a significant improvement of the resistance to adhesive wear.
