Microstructure modification of CGDS and HVOF sprayed CoNiCrAlY bond coat remelted by electron beam
Original language description
In the present work two techniques are combined to optimise bond coat properties before TBC application, the cold gas dynamic spraying (CGDS) and electron beam remelting (EB). Results of the work focused on comparison of HVOF and CGDS CoNiCrAlY bond coats are firstly presented. Than the effect of the electron beam remelting of the CoNiCrAlY coating manufactured by HVOF and CGDS deposition techniques is deeply investigated. Scanning electron microscopy, light microscopy, and, in addition, X-Ray diffraction techniques were performed to characterize the phase modification and microstructure composition changes before and after the treatment. The microstructural and phase analyses have been supported by microhardness and nanohardness investigation and other necessary supporting techniques.
