Apply the advantages that high-efficient, speed is fast, formation strength of coating is high.The basic principle of cold spraying forming is that high pressure gas passes through scaling spray
Pipe Laval jet pipe generates supersonic speed (300-1200 m/s) flowing, and ultrafine solids powder particle is sent into air-flow from axis direction,
Powder particle (1-75 μm) is accelerated by high-speed flow, hits matrix surface with complete solid state, passes through biggish plastic deformation
So that powder particle is deposited on matrix and is formed coating, entire 3D solid is formed after accumulating layer by layer.Although using it is this at
Single layer two-dimensional surface film unit obtained by shape method has more relative to layer unit is formed by using other traditional methods

In in throat or outlet portion more than the throat.
The documents of Patent No. CN200510030207.4 and CN00253384.7 disclose a kind of cold spraying use
Nozzle, said nozzle solve the problems, such as powder stopped nozzles in spraying process to a certain extent.
However that there is also flows is larger, supersonic speed section distance is shorter, jet expansion jet stream convergence property is bad etc. for said nozzle
Problem just more requires powder jet stream when needing and forming film unit using cold spraying method especially in microelectronic field
While with biggish speed, convergence property will also be got well.Obviously, existing spray head is difficult to meet particle three-dimensional jet printing technology
It is required that, it is necessary to a kind of novel partculate three-dimensional jet printing spray head is developed, to realize that composite particles in the base can control on demand
