Abstract
Cold spray devices and systems are disclosed. They include a flowpath having an inlet adapted for receiving communication with two or more inputs and an outlet adapted to discharge the two or more inputs. A discharge nozzle may be included in the flowpath of the outlet and a confluence may be included in the flowpath at the inlet for combining the two or more inputs. A nozzle body houses the discharge nozzle separate and downstream from the confluence of the two inputs.
Claims7
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.
