Abstract:

A method of maintaining a non-obstructed interior opening in a kinetic spray nozzle is disclosed. The method includes the steps of providing a mixture of particles including first particle population and a second particle population; entraining the mixture of particles into a flow of a gas at a temperature below the melt temperature of the particle populations; and directing the mixture of particles entrained in the flow of gas through a supersonic nozzle to accelerate the first particle population to a velocity sufficient to result in adherence of the first particle population on a substrate positioned opposite the nozzle. The operating conditions of the kinetic spray system are selected such that the second particle population is not accelerated to a velocity sufficient to result in adherence when it impacts the substrate. The inclusion of the second particle population maintains the supersonic nozzle in a non-obstructed condition and also enables one to raise the main gas operating temperature to a much higher level, thereby increasing the deposition efficiency of the first particle population.

US Classification:

165/080200

Abstract:

A thermal stack laminate and a process for producing the same are disclosed. The thermal stack laminate includes a baseplate formed from a heat sink material that has on a first surface a very thin thermally sprayed alumina layer to serve as a dielectric and attached to the alumina is a kinetic spray applied solderable layer. An electrical component is attached to the thermal stack laminate by solder. The thermal stack laminate optionally includes a kinetic spray applied first and/or second metal matrix composite layer between the baseplate and the alumina layer and between the alumina layer and the solderable material. In addition, one other optional layer comprises a first layer of the solderable material applied via a thermal spray process followed by the remainder of the solderable material applied by a kinetic spray process.

Abstract:

A method is disclosed for the aluminum metalization of ceramics using a kinetic spray system. The method is rapid, does not require any surface preparation of the ceramic substrate, and produces a coating having properties similar to bulk aluminum. The method permits aluminum coatings of from microns to centimeters in thickness. The method further more enables one to quickly apply copper or copper alloys to the aluminum metalization to provide for soldering pads to attach other components. The method finds special application in the area of high powered electronics.

US Classification:

427446000

Abstract:

A method for deposition of a metal layer onto plastic materials is disclosed. The method allows for formation of long length strain gauges and deposition of high melting temperature metals onto plastic materials. The method comprises initially depositing a pattern of powder particles onto the plastic material using a kinetic spray process. Then the high melting temperature metal layer is deposited using a thermal spray process. The metal layer only adheres to the pattern of the powder particles and not to the plastic substrate. To form a stain gauge the powder particles are deposited in a discontinuous non-electrically conductive density on the plastic material. Then a metal layer is deposited using a thermal spray process and a metal having a variable resistance. The metal forms a continuous and electrically conductive pathway having a resistance that changes as stress is applied to the substrate.

US Classification:

Abstract:

A nozzle assembly for a kinetic spray system includes a convergent portion, a throat portion, and a divergent portion, each cooperating together to define a passage therethrough for passing a mixture of powder particles suspended in a flow of a high pressure heated gas. The nozzle assembly further includes an extension portion attached to the divergent portion and extending to a distal end a pre-determined length from the divergent portion of the nozzle assembly. The extension portion permits a dragging force exerted on the powder particles by the flow of high pressure heated gas to act upon the powder particles for a longer duration of time, thereby permitting the powder particles to accelerate to a greater velocity than has been previously achievable.
