СПОСОБ НАПЫЛЕНИЯ ПОКРЫТИЙ С ПОМОЩЬЮ ОРУЖЕЙНОГО ПОРОХА И УСТАНОВКА ДЛЯ ЕГО РЕАЛИЗАЦИИ

FIELD: mechanical engineering.SUBSTANCE: invention relates to the technique of coating by spraying a powder material. During the coating process, a forward movement of the piston is carried out from the gas outlet channel, in which the return spring is compressed. During the movement of the piston, the channels in the dispenser body and the piston begin to combine. From the bunkers, through the channels in the dispenser body, the sprayed powder and gunpowder enter the corresponding vertical channels of the piston. Then the piston is moved to the gas outlet channel under the action of a return spring. At the same time, when the extreme position of the piston is reached, the sprayed powder is discharged into the barrel channel and the powder into the explosive chamber. After that, the powder is ignited in the explosive chamber. The pressure of the resulting gases creates acceleration of the sprayed material through the bore to form a coating, and also, impacting the end part of the piston, returns it to its original position, thereby closing the cycle. The installation for spraying coatings with gunpowder in the above way contains a barrel closed from the side of the explosive chamber, in which an igniter and a dispenser are installed. There are two vertical channels on top of the barrel. At the end of the barrel, a gas outlet channel is made, communicating with the explosive chamber in which the igniter is located. A dispenser is installed on top of the barrel, made in the form of an oblong structure, inside the body of which there is a spring-loaded piston with two vertical channels for the corresponding technological materials: sprayed powder and gunpowder. Two channels are made on top of the dispenser body, which communicate with the bunkers for the sprayed powder and gunpowder located on top of the dispenser.EFFECT: invention provides an increase in the spraying performance and reliability of the installation by reducing its design complexity.3 cl, 4 dwg ...

Spray processing of porous medical devices

Thermal spray processing and cold spray processing are utilized to manufacture porous starting materials (such as tube stock, wire and substrate sheets) from biocompatible metals, metal alloys, ceramics and polymers that may be further processed into porous medical devices, such as stents. The spray processes are also used to form porous coatings on consolidated biocompatible medical devices. The porous substrates and coatings may be used as a reservoir to hold a drug or therapeutic agent for elution in the body. The spray-formed porous substrates and coatings may be functionally graded to allow direct control of drug elution without an additional polymer topcoat. The spray processes are also used to apply the drug or agent to the porous substrate or coating when drug or agent is robust enough to withstand the temperatures and velocities of the spray process with minimal degradation.

Flameless plastic coating apparatus and method therefor

A stream of hot air passes from a combustion chamber through an application gun to a preheated substrate. A powdered thermoplastic is fed into the application gun. The hot air stream heats the powdered thermoplastic to its fusion temperature and transports it to the substrate.

Thermal spray systems

A thermal spray system includes a combustion unit connected to at least one port for supplying a flow of a combustible fluid from an external source of fuel and oxidant. The combustion unit includes a permeable burner block constructed to receive said combustible fluid from and to generate a high-energy stream of gas. The thermal spray system also includes an exhaust nozzle constructed to direct the high-energy stream of gas toward a substrate, and a material delivery unit constructed to deliver a material into the high-energy stream of gas to form a highly energized stream of particles. When the thermal spray system is used for bead blasting, the provided material is an abrasive material. Alternatively, when the thermal spray system is used for coating a substrate, the provided material is a coating material. The material delivery unit may be an injector or an electric arc unit. Instead of the combustion unit burning the combustible fluid, the thermal spray system may include a source of a high-pressure preheated gas such as a plasma source or an electric heat exchange source.

Highly concentrated supersonic liquified material flame spray method and apparatus

Within ultra high velocity flame spray apparatus, the oxy-fuel products of combustion under pressure exit from an internal burner and pass through a spray nozzle of extended length. Metal or ceramic material in thin diameter rod form or as particles are fed to the nozzle inlet at a point at or just ahead of the throat of the nozzle bore. The exceptionally long nozzle flow path and the mode of introduction of the material into the flame spray insures a concentrated and highly focussed core of spray material for material spray coating downstream of the nozzle at supersonic speed.

Apparatus and process for producing high density thermal spray coatings

An attachment for supersonic thermal spray equipment by which inert shield gas is directed radially outwardly about the central core of a supersonic, particle-carrying flame to isolate the same from ambient atmosphere. The shield gas is injected tangentially against the inner surface of a constraining tube attached to and extending from the discharge end of the thermal spray gun nozzle, causing the shield gas to assume a helical flow path which persists until after it exits the tube and impacts the work piece. A process using the shielding apparatus with a high-velocity, thermal spray gun and employing oxygen and hydrogen as gases of combustion and inert gas to introduce metal powder, having a narrow particle size distribution and low oxygen content, into the high-velocity combustion gases, produces significantly improved, high-density, low-oxide metal coatings on a substrate.
