Abstract (en)

[origin: EP1213363A1] Production of wear-resistant edge layers on workpieces comprises subjecting a component which has been solution annealed conventionally at a temperature Tcsa1 and heat treated conventionally at a temperature Tcpa1 to renewed short term solution annealing of the edge layer at a temperature of Tsaa Tcsa1 and a holding time of delta tssa 12 seconds; and further heat treating the inside of the component and the edge layer at a temperature of Tspa Tcpa1.
