1. A cold spray device comprising:
a discharge system comprising:
a nozzle body for discharging a gas-powder mixture;
a gas-powder mixture input side on the nozzle body adapted for downstream communication with a gas-powder mixing manifold;
a gas-powder mixture output side on the nozzle body;
a flowpath system which communicates a powder and a heated gas to the mixing manifold; the flowpath system comprising:
a gas-powder flowpath in communication with the input side and output side of the nozzle body; and wherein the gas-powder mixture comprises a gas temperature and powder temperature, wherein the powder temperature is generally at the gas temperature at the input side; and
a control system operably configured to control the discharge system and the flowpath system and monitor inputs and responses to detected pressures and temperatures, the control system comprising:
at least one sensor housed within the nozzle body for measuring a pressure of the gas-powder mixture prior to and after being discharged from the output side of the nozzle body.
