XRD AND SEM STUDY OF AL2O3/WS2 NANOSTRUCTURES

In this paper the characteristics of Al2O3/WS2 nanocomposite layer will be presented. The Al2O3/WS2 oxide layers were obtained by hard anodizing process on an aluminum alloy. The main advantage of oxide layers prepared by hard anodizing is good adhesion to the base. Another benefit of anodizing oxide layers is the possibility to control tribological properties, mainly friction coefficient through the change in porosity, thickness or microhardness of the layer as a result of technological parameters ( temperature, solution composition or current density change). During the process of growing of nanoceramic Al2O3 fibres, the dispersed particles of WS2 adsorb on nanofiber surfaces and subsequently are constructed with ternary electrolyte anions. The characteristics of matrix of Al2O3 nanofibers with dispered WS2 phase were performed using scaning electron microscopy and X-ray structural studies.
