| Abstract: |
Demanded characteristics for thermal spray feedstock powders can be very different, depending on the spraying process, the operating conditions, the desired properties of the final coating, etc. Besides the intrinsic material properties, the technical requirements for the thermal spraying feedstock powders include good flowability and sprayability. They are greatly affected by the particle size, shape and morphology as well as particle size distribution. That is why thermal spray feedstock powder production processes must be reliable and flexible.
The main parameters to control the synthes is process are composition and structure of the charge mixture (including type and amount of additives and fillers); reactants dispersity; relative density and charge volume; initial temperature of the sample, etc.
As for new mix materials, which involved intermetallic alloys, refractory alloys, ceramics, etc., are proposed as possible alternative composite well-know materials for aviation industry.
