On the Principles of the Additive Technology Implementation of Composite Magnetic Coating’s Formation on Non-Magnetic Substrates by Laser Welding of Micro Powders

The article discusses the formation of coatings with magnetic properties on non-magnetic substrates by the method of additive technology of metal powders using high power pulsed laser radiation. An instrumental base for the development of methods for creating local magnetic zones of a given configuration has been described. Approaches to create methods of additive welding of solid solution magnetic zones on the basis of micro-powders of metal alloys have been developed. The coatings with soft magnetic properties on the basis of powders of bronze and iron-containing "Inconel" alloy on non-magnetic substrates were obtained by laser welding. The structural inhomogeneity at the interface of the substrate and the solid solution were studied. Data on hardness and magnetic properties were obtained for formed magnetically soft materials.
