Laser cladding process of a high alloyed powder metallurgical tool steel was studied for die repairing purposes. The low hardness obtained after the deposition process was improved by later tempering cycles, achieving crack free coatings with hardness well above 700 HV. The effect of different post tempering cycles was investigated in order to determine the optimal temperature range. The microstructure...
A study of the laser cladding of powder metallurgical tool steels has been carried out. CPM 10V and Vanadis 4 Extra tool steel powders have been deposited on Vanadis 4 Extra tool steel plates, for repairing purposes, using a Nd:YAG laser. The microstructure of the laser cladding samples was investigated using optical and scanning electron microscopes. The volumetric fraction of retained austenite...
