    Abstract: On spray-forming metals onto a substrate from which the sprayed coating is to be detached, unwanted adhesion may occur, even to a smooth substrate. Conversely, if the coating is meant to adhere, it may accidentally delaminate, even from a roughened substrate.
    By vibrating the substrate, marginally adherent splats will be encouraged to detach themselves while, on the other hand, well adherent splats will not be affected.

    Abstract: A method of applying a lubricious coating of a material such as a fluoropolymer to a cutting edge of a blade includes providing the blade having the cutting edge including a tip end, a first facet, and a second facet with the first facet and the second facet adjacent the tip end. The method further includes generating a plasma stream and directing the plasma stream towards the cutting edge. The method further includes introducing a fluid stream containing a dispersion including the fluoropolymer into the plasma stream, thereby simultaneously plasma treating the cutting edge and depositing solids of the dispersion onto the cutting edge.

    Abstract: A thermal spray apparatus to apply coatings to external and internal surfaces in restricted areas is provided. The apparatus includes: a fuel input line; an oxidizing gas input line; coolant input and outlet; a combustion chamber that facilitates primary combustion; a diverging section that splits the primary combustion flow into two or more streams; an elbow section that redirects the combustion streams; a convergent/divergent nozzle; a convergence section that recombines the combustion streams into a single combustion stream within an injection zone of the convergent/divergent nozzle; and a feedstock injector for the injection of feedstock material for forming said coatings into said injection zone of the convergent/divergent nozzle; wherein the convergent/divergent nozzle has a nozzle throat downstream of the injection zone whereby in operation the injection pressure of the feedstock material upstream of the nozzle throat approximates the pressure of the combustion stream within the injection zone. The apparatus may also include the use of an accelerating gas.
