..., the achievable spray parameters were 2 MPa (290 psi) and 400 °C (750 °F). The coil heater required the use of a hot gas hose to lead the gas to the gun ( Fig. 4.1 ). Here, energy was lost and the process temperature was limited by the hose. Furthermore, the flexibility of the cold spray gun was restricted...
