Original Abstract

The contribution is focused on formation and growth of intermetallic phases and eutectic in iron coated aluminium alloy systems. The 99.5Fe powder was used to produce the coating, by means of high velocity oxyfuel spraying, onto 5mm thick 99.5Al sheet surface. As-sprayed samples were annealed in the range of 600 - 800 C in ambient atmosphere. Based on temperature height an isothermal dwell was from several minutes up to a few hours. Isothermal annealing below the melting point of aluminium-iron eutectic resulting in a formation of iron-aluminides within the iron coatings. Nevertheless, with increasing temperature, exceeding the melting point of eutectic, iron diffuse into the aluminius substrate and eutectic alloy with various morphologies start to form. The microstructure of produced alloys were obtained by scanning electron microscope. Layer thickness and morphology measurements were evaluated by means of image analysis. Chemical compositions were estimated using energy dispersive microanalysis.
