I came across Roberts article of spraying bondcoats with HVAF. Very interesting read!
The Potential of High-Velocity Air-Fuel Spraying (HVAF) to Manufacture Bond Coats for Thermal Barrier Coating Systems - Journal of Thermal Spray Technology
Just wanted to get some thoughts on challenges here!
- Are there any supply chain concerns with this or this is not as accepted by all coating makers yet?
- Compared to bondcoats with APS will there be lower bond strength due to possible lower spray temperatures?
- What if a very fine particle size is sprayed with HVAF in-order to optimize the liquid permeability for a super dense bondcoat. Will it work?
