Wear investigation of selective α-Fe2O3 oxide layers generated on surfaces for dry sheet metal forming

To realize a dry sheet metal forming process, alpha-Fe2O3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens examined. The oxide layers were generated in a new hybrid batch furnace. The layer generation on all specimens of the tool steel 1.2379 used was performed at a target temperature below the annealing temperature (approximate to 510 degrees C). Friction coefficients were examined with plane strip drawing tests. Wear experiments with oxidized wear specimens with variable surface topographies were carried out up to several thousand strokes per surface condition. (C) 2018 The Authors.
