Abstract
Przedmiotem wynalazku jest sposób niskociśnieniowego natryskiwania na zimno powłok z proszków cząstek stałych i układ do niskociśnieniowego natryskiwania na zimno powłok z proszków cząstek stałych, gdzie w atmosferze próżni na częściach maszyn i produktach medycznych, natryskiwane są powłoki o dowolnej grubości z materiałów metalicznych i ceramicznych, co ma szczególne zastosowanie w medycynie, motoryzacji, elektronice i lotnictwie. Układ zawiera komorę fluidyzacyjną (1), która wewnątrz ma masę porowatą (2) dolną ułożoną na powierzchni dna i górną pod pokrywą, przy czym w dolnej części na zewnątrz komory fluidyzacyjnej (1) załączony jest elektrowibrator (3). Gaz pod ciśnieniem 2 bar wprowadza się i przepuszcza przez masę porowatą (2), gdzie w wibrującej komorze fluidyzacyjnej (1) tworzy się aerozol (9), który zostaje przesłany do dyszy natryskowej (13) niskociśnieniowego pistoletu natryskowego (11) z nagrzewnicą (10), umieszczonych na stałe w adapterze (14) osadzonym w komorze próżniowej (15). Pierwszym przewodem doprowadzającym (5) strumień gazu, wprowadza się do dyszy natryskowej (13) pistoletu natryskowego (11), natomiast osobnym przewodem (8) przez wlot (12) w dyszy natryskowej (13) radialnie wprowadza się aerozol (9), który w dyszy (13) pistoletu natryskowego (11) zostaje zasysany oraz przyspieszony dzięki strumieniowi gazu pod ciśnieniem, korzystnie 8 bar i kieruje się go na powierzchnię natryskiwanego elementu (19), który jest zamocowany w uchwycie (20) układu ruchu (21), wewnątrz komory próżniowej (15), realizującym poruszanie się natryskiwanego elementu (19) w płaszczyźnie X — Y na prowadnicy pionowej (22) i poziomej (23) oraz ruchem obrotowym względem pistoletu natryskowego (11). Następuje łączenie się natryskiwanych cząstek z podłożem i między sobą, gdzie prędkość cząstek proszku uderzających o powierzchnię podłoża natryskiwanego elementu (19) wynosi 300 - 1200 m/s, a temperatura cząstek podczas uderzenia mieści się w przedziale 21 – 600°C. Po zderzeniu z powierzchnią natryskiwanego elementu (19) cząstki ulegają deformacji i wiążą się z powierzchnią podłoża tworząc powłokę.The subject of the invention is a method of low pressure cold spraying of coatings made of solid particles powders and a system for low pressure cold spraying of coatings made of solid particles powders, where in a vacuum atmosphere coatings of metallic and ceramic materials of any thickness are sprayed on has a particular application in medicine, automotive, electronics and aviation. The system comprises a fluidization chamber (1), which inside has a lower porous mass (2) laid on the bottom surface and an upper one under the cover, and an electibrator (3) is connected in the lower part outside the fluidization chamber (1). The gas under a pressure of 2 bar is introduced and passed through the porous mass (2), where an aerosol (9) is formed in the vibrating fluidization chamber (1), which is sent to the spray nozzle (13) of the low-pressure spray gun (11) with a heater (10). ), placed permanently in the adapter (14) placed in the vacuum chamber (15). The first gas supply conduit (5) enters the spray nozzle (13) of the spray gun (11), while through a separate conduit (8) through the inlet (12) in the spray nozzle (13), the aerosol (9) is radially introduced into the nozzle (13) of the spray gun (11) is sucked in and accelerated by the jet of gas under pressure, preferably 8 bar, and directed to the surface of the sprayed element (19), which is mounted in the holder (20) of the motion system (21) inside the chamber (15), which moves the sprayed element (19) in the X-Y plane on the vertical (22) and horizontal (23) guides and rotates in relation to the spray gun (11). The sprayed particles combine with the substrate and with each other, where the velocity of the powder particles hitting the surface of the substrate of the sprayed element (19) is 300 - 1200 m / s, and the temperature of the particles during the impact is in the range of 21 - 600 ° C. After colliding with the surface of the injection-molded part (19), the particles deform and bind with the substrate surface, forming a coating.
