In the present study, the opportunity to improve the coatings properties using re-melting technique is studied. In the aim to determine the influence of the re-melting on the properties of coatings, the experimental study was performed. The surface of S235J0 steel was coated using three different re-melting methods with different heating duration. The mixture of NiCrFeCSiB alloy powders and carbides of WC type was used for spraying. The principal characteristics of the sprayed coatings were examined and compared with each other. The tests allowed concluding that the introduction of the re-melting process of different duration has tangible impact upon the structure, hardness and wearing resistance of the coatings
