ILIE BUTNARIU, NICOLAE CONSTANTIN STRUCTURAL METALLOGRAPHIC INVESTIGATIONS OF NEW COMPOSITE MATERIALS, USED AS COATING LAYERS
The paper presents the results of metallographic investigations on the structural properties of new composite materials to be used as coatings for the manufacture and refurbishment of rolling stock components. Structural investigations were carried out both on the coating layer of the composite material and on the interface between the coating layer and the base metal material, using optical microscopy and electron microscopy. The obtained structural results have confirmed that these new composite materials have particular structural properties and as such can be used as coatings for the manufacture and refurbishing of metallic parts for the rolling stock industry and the chemical and metallurgical industry, presenting both economic and environmental advantages.
