Cold-spray nozzle
Systems, apparatus, and method for manufacturing are disclosed. In an aspect, the apparatus may be a cold-spray nozzle. The cold-spray nozzle may include a variable diameter convergent part. The cold-spray nozzle may also include a variable diameter divergent part. The variable diameter divergent part may form a diffuser. Additionally, The cold-spray nozzle may include a ring portion. The ring portion may couple the variable diameter convergent part and the variable diameter divergent part. Additionally, the ring portion may control the opening to the diffuser.
1. A cold-spray device comprising:
a material hopper;
a pressurized gas feed coupled to the material hopper; and
a cold-spray nozzle coupled to the pressurized gas feed and configured to receive material from the material hopper, the cold-spray nozzle including:
a variable diameter convergent part;
a variable diameter divergent part forming a diffuser; and
a ring portion coupling the variable diameter convergent part and the variable diameter divergent part, wherein a size of the ring portion controls a flow of a cold-spray through an opening between the variable diameter convergent part and the variable diameter divergent part;
wherein the nozzle contains a series of hinges and overlapping sheets within the nozzle, the hinges and overlapping sheets configured to control a diameter of the variable diameter divergent part.
2. The cold-spray device of claim 1 , wherein the variable diameter convergent part comprises a nozzle.
3. The cold-spray device of claim 1 , further comprising a movable build platform.
