Abstract

Przedmiotem wynalazku jest sposób nanoszenia funkcjonalnych powłok zawiesin w szczególności z materiałów proszkowych o wielkości submikronowej lub manometrycznej, które znajdują zastosowanie w szeroko pojętej dziedzinie inżynierii materiałowej. Sposób według wynalazku charakteryzuje się tym, że powierzchnię będącą podłożem oczyszcza się poprzez płukanie cieczą, a następnie poddaje się ją obróbce strumieniowo - ściernej, po czym nanosi się warstwę znaną metodą natryskiwania zimnym gazem, przy czym warstwę nanosi się poprzez wprowadzenie zawiesiny, najkorzystniej w postaci fluidalnej, przy odpowiednim ciśnieniu w zakresie od 0,01 do 5 MPa do strumienia doprowadzonego przez dyszę napylającą gazu roboczego, prowadzącego do rozpylenia zawiesiny i bombardowania podłoża częściowo odparowanymi cząstkami, zawierającymi submikronowe lub manometryczne elementy nanoszonego materiału tworzącego warstwę, przy czym temperatura gazu roboczego nie przekracza połowy średniej temperatury topnienia cząstek materiału powłoki i nie jest wyższa niż 1500°C przy jednoczesnym ciśnieniu do 10 MPa, a rozpylone cząstki uderzają z prędkością od 100 m/s do 1000 m/s o powierzchnię podłożaThe subject of the invention is a method of applying functional coatings of suspensions, in particular, of powder materials of submicron or manometric size, which are used in the broadly understood field of materials science. The method according to the invention is characterized in that the substrate surface is cleaned by rinsing with a liquid, followed by abrasive blasting, and then applying a layer by a conventional cold gas spraying method, the layer being applied by introducing a slurry, most preferably in the form of a slurry. fluidized bed at an appropriate pressure ranging from 0.01 to 5 MPa to the stream supplied through the spraying nozzle of the working gas, leading to atomization of the suspension and bombardment of the substrate with partially vaporized particles, containing submicron or manometric elements of the applied film-forming material, the temperature of the working gas not exceeds half of the average melting point of the particles of the coating material and is not higher than 1500 ° C with a simultaneous pressure of up to 10 MPa, and the sprayed particles hit the surface of the substrate at a speed of 100 m / s to 1000 m / s
