Original Abstract

Powder liquid method was used for aluminides diffusion coatings formation on the Inconel 713LC nickel-based superalloy. Two different powder mixtures (Al and Al+Si) in organic binder solution were prepared. Coating s depositoon onto the substrate surface was realized by spraying. Two-stage heat treatment under the argon-folw atmosphere was designed. First stage at 200oC was used to decompose organic binder. In the second stage at 1000oC the elements from the coating interact with the substrate. Protective intermetallic layer ane an interaction zone between the layer and substrate start to form. Elements interaction and phase transformations during annealing at 1000oC up to 600 min were studied. For this study the light micrtoscopy, scanning electron microscopy, energy dispersive microanalysis, x-ray diffraction phase analysis, microhardness measurement, and image analysis methods were used.
