Abstract [en]
The aim of this study was to investigate the effect of a magnetic field on the wear behavior of an IN718 layer applied by laser cladding on GTD-111 superalloy. The results showed that by increasing the intensity of the magnetic induction field from 25 mT to 75 mT, the grains become finer and the area of the equiaxed grains increases. This increased the hardness and decreased the porosity of the cladding zone (CZ). However, the greatest magnetostrictive effect was produced at a magnetic intensity of 25 mT, which reduced the elastic modulus of the specimen. Under such conditions, the hardness ratio to the elastic modulus reached its maximum value (3.97), which resulted in increased wear resistance of the CZ. © 2022 Elsevier Ltd
