Abstract
Electric arc flux-cored wire deposition of coatings results in formation of residual tensile stresses, which may cause initiation of cracks in the coatings, or their fracture, especially in finishing operations. It is shown that coating deposition parameters have a substantial effect both on the kinetics of formation of internal stresses, and on their residual level
Keywords: electric arc spraying, coating, flux-cored wire, coating deposition parameters, internal stress, cohesion, split ring
