Popis: The development of hard-facing coatings has become technologically significant in many industries where wear can cause severe damage on different components. One approach is the production of metal matrix composites (MMC) layers, consisting of a mixture of hard ceramic phases immersed in a ductile metal matrix. In this work, a study of the development of NiCr-WC hard-facing layers by means of laser cladding (LC) is presented. For the reinforcement phase, spheroidal fused tungsten carbides have been used by virtue of its exceptional hardness which may range from 2500 HV up 3300 HV. The properties of the layers are analyzed and discussed in relation to the LC parameters used in the process.
