STUDY OF THE ELECTRON BEAM REMELTING OF A CGDS DEPOSITED CONICRALY LAYERS
Original language description
Cold Gas Dynamic Spraying (CGDS) method was used in order to obtain very dense and good adhesive CoNiCrAIY-coatings deposited onto nickel-based alloy and subsequently remelted by electron beam (EB) up to depth of about 90 mu m. The CGDS process-a relatively new coating technology is based on the high velocity impingement of small solid particles on the substrate. In this process, the particles are accelerated by supersonic gas jet at the heated gas temperature, which is usually lower than the melting point of the powder material. The objective of this work is to investigate the influence of the parameters used in electron beam remelting even the effect of double EB remelting on the microstructural changes and state of the coating. Changes of the coatings morphology and structure were analyzed by scanning electron microscopy (SEM) and X-ray diffraction technique (XRD). The experimental results demonstrated that there are advantages at using the pulsed EB surface modification technique. The double remelting process improved the coating properties in terms of porosity, strength and chemical homogeneity.
