Assessment of galling performance of tools steel andsheets metals used in forming
(English)Manuscript (preprint) (Other academic)
A number of tool steel and sheet metal combinations were tested with respect to gallingbehaviour. Tests were performed both in dry and lubricated sliding. The tested sheet gradeswere three carbon steels, Docol 1200 M, Docol 1000 DP and DC01 two stainless steels,EN 1.4301 and EN 1.4509 one aluminium grade, AA 1193 and one titanium grade ti6al4vor EN 3.7164. The tool steels were two high speed steels and three powder metallurgicaltool steel grades.It was found that the tool steels performed equally well on dry sheets and the gradescould not be adequately separated. Under lubricated sliding on the Docol 1200 M sheetsthe difference between two PM materials was however notable.The addition of lubrication increased the tool life significantly for all materials excepttitanium. Titanium showed signs of galling immediately even if the sheets were lubricated.
