The importance of metal coating technologies drives the continuous improvement of metal deposition technologies for application in a wide range of industrial applications. This work presents the foundations of a new process technology for the deposition of Ti and Ti64 coatings on various substrates using supersonic powder streams and impact site laser heating. Full density metallic deposits are obtained under appropriate impact conditions without the need for transiting the melting point of the deposited material or substrate leading to large energy savings. Details of the experimental approach will be presented along with the general characteristics of the titanium coatings produced using this novel coatings method. Potential applications of this coating technology will also be presented in addition to direct performance and cost comparisons of competing coating technologies compared to the new Supersonic Laser Deposition method (SLD).
