摘要： A method is disclosed for direct application of a brazing flux material to a brazing surface. The method includes the step of applying a brazing filler material to a substrate utilizing a kinetic spray process to form a brazing surface. Following application of the brazing filler material to the substrate brazing flux material can be directly applied to the brazing surface as either a dry powder or a wet slurry. The nature of the brazing surface allows the applied flux material to adhere to the surface without the utilization of additional binders or resin materials.

摘要： A new gas collimator for use in a kinetic spray system is disclosed. The collimator reduces turbulence of the main gas and results in significant increases in the amount of particles deposited on a substrate using the system. Kinetic spray nozzles incorporating the new collimator also have significantly higher deposition efficiencies. The new collimator enables the main gas temperature to be reduced while permitting much higher depositions and deposition efficiencies compared to the prior art collimator. Also disclosed is a low pressure injection method for a kinetic spray system. The coaxial, low pressure injection method enables the use of low pressure powder feeders, which are low cost, technologically mature, and widely available commercially. The coaxial injection method overcomes several undesirable effects associated with prior art high pressure injection methods.

摘要： 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.

摘要： An improved kinetic spray nozzle system design is disclosed. The nozzle includes an improved powder injector having an injector tube and a sleeve wherein the injector tube is received in the sleeve and secured to the sleeve. The powder injector further includes an air gap defined between an inner diameter of the sleeve and an outer diameter of the injector tube wherein the air gap is from 50 to 200 microns. The improved injector is capable of spraying a variety of powder materials including hard and “gummy” powders for without clogging for extended periods of time whereas under similar spray conditions previous designs became completely plugged within minutes. The improved injector design enabled the use of higher main gas temperatures to achieve improved coating formation and deposition efficiencies. Most importantly, the improved design makes it possible to use the kinetic spray system with a wide range of powder materials in a manufacturing setting without interruptions caused by powder injector clogging related problems.
