We study the influence of phase composition of the rods of hydraulic cylinders fused from the cored wires on their local corrosion. We investigate the corrosion resistance of deposited layers in a 3% NaCl solution at room temperature and the influence of their phase composition on the character of corrosion defects. It is shown that the layers deposited from cored wires with a chromium content of 14–20 wt.% are characterized by strong local striplike corrosion whose intensity depends on the phase composition of the layer. It is also demonstrated that the corrosion resistance of the austenitic matrix increases with the ferrite content in the structure of layers,. © 2015 Springer Science+Business Media New York.

Data showing the efficiency of using the new flux-cored wire, Veltek-N285C, for reconditioning rapidly worn crane wheels are presented. The metal deposited with this wire contains metastable austenite, reinforced with carbides and undergoing dynamic deformation martensitic transformation during loading in service (the self-quenching effect in loading). Consequently, the internal resources of the material can be utilized. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
