Determination of optimum tempering temperature in hard facing of the forging dies for working at elevated temperatures

Abstract

In this paper is presented only a part of the complex procedure that must be conducted in order to successfully regenerate damaged forging dies by hard facing. After identification of the type and cause of the dies damage, we have selected the procedure and parameters of hard facing, that were further corrected by test hard facing on models. In that way, we were able to relate the output results with the repairing technology. This made possible selection of optimum hard facing technology for the adopted procedure and the filler material, as well as for the chosen regime of thermal treatment.
