Abstract

The paper considers the possibility of obtaining composite banded coatings by laser cladding. Regularities of distribution of
microhardness in cross-section of homogeneous and composite banded coatings are identified. Shows periodic change of microhardness in composite banded coatings received by laser cladding. Wear resistance of homogeneous and composite banded coatings are investigated. It will be shown, that double layer composite coatings wear-resistance is higher what is the same for nickel based selffluxing alloys coatings.
