Abstract:
A glimpse of the current industry efforts in using cold spray coatings, in repair and refurbishment of structural gas turbine components will be presented. One of them makes use of the cold spray coating process as an alternate to conventional welding, for refurbishment of Oil and Gas components. The technology from a coupon level to a component level, using the new spray on welding process of repair, was developed and industrialized. Detailed characterization of the cold spray coatings, in terms of the bonding mechanism and thermal stability, along with correlations between the residual stress and fatigue behaviour, will be presented, for a variety of hard Superalloy coatings, for various repair applications.
