摘要： Methods and apparatus for reducing the TPM level of a diesel engine exhaust stream by providing a suitable oxidation catalyst into the exhaust train. The oxidation catalyst may be incorporated into a thermal insulative coating on the inner surface of the exhaust train, particularly the exhaust manifold and exhaust pipes prior to the turbocharger. Alternatively, when the exhaust train includes a turbocharger, the catalyst can be in a separate monolithic unit between the engine and the turbocharger. The system may also include an improved diesel oxidation catalyst unit having a metal monolithic substrate. The oxidation catalyst can also be incorporated into a thermal insulative coating inside the cylinders, particularly on non-rubbing surfaces such as The invention also includes the use of a protective mullite top coat on the thermal coating. A further embodiment is the use of a stainless steel bond coat to bind the thermal coating to a metallic substrate, particularly an aluminum substrate.

摘要： Manufacture of glass mold plungers utilizes a thermal spray gun having combustion chamber with an open channel for propelling combustion products into the ambient atmosphere at supersonic velocity. The method comprises injecting into the chamber a combustible mixture of combustion gas and oxygen at a pressure in the chamber of at least two atmospheres above ambient atmospheric pressure, feeding into the chamber a powder comprising self-fluxing alloy particles, and combusting the combustible mixture in the chamber means whereby a supersonic spray stream containing the powder is propelled through the open channel. The spray stream is directed toward a glass mold plunger substrate such as to produce a coating thereon which is ground and polished. The coating may be fused prior to grinding.

摘要： A method of and apparatus for producing a dense and tenacious coating with a thermal spray gun including a nozzle member and a gas cap. The gas cap extends from the nozzle and has an inwardly facing cylindrical wall defining a combustion chamber with an open end and an opposite end bounded by the nozzle. An annular flow of a combustible mixture is injected at a pressure of at least two bar above atmospheric pressure from the nozzle coaxially into the combustion chamber. An annular outer flow of pressurized air is injected from the nozzle adjacent to the cylindrical wall. Heat fusible powder entrained in a carrier gas is fed axially from the nozzle into the combustion chamber. An annular inner flow of pressurized air is injected from the nozzle into the combustion chamber coaxially between the combustible mixture and the powder-carrier gas. Upon combusting the annular mixture a supersonic spray stream containing the powder is propelled through the open end to produce a coating. A second gas cap with a different size open end may be selected to effect a different size spray stream.

摘要： The invention contemplates improved nozzle structure removably securable to a gas-distributor body for delivering and discharging independent flows of combustible-gas mixture and of powder material to be flame-sprayed by a gas torch to which the nozzle is fitted. The combustible-gas mixture is successively accommodated in annular manifold regions of relatively large sectional area, respectively upstream and downstream from an intermediate annular manifold region of relatively restricted sectional area, for inhibiting flash-back to the gas distributor and for effectively limiting any flash-back effects to the manifold region downstream of the annular restriction.

摘要： A gas cap for a thermal spray gun has a passage therethrough including an entrance channel, an exit channel, and an intermediate channel connecting between the entrance and exit channels. The entrance channel is cylindrical on an entrance axis, and the exit channel is convergingly conical on an exit axis oriented at 45.degree. to the entrance axis. The intermediate channel is symmetrical to the plane of the entrance and exit axes and has a near portion and a far portion. The near portion is semicylindrical about the entrance axis, and the far portion is semicylindrical about a far axis segment lying in the plane. That segment is offset from the entrance axis away from the exit end of the gas cap, and is oriented at 14.degree. to the entrance axis, the three axes intersecting at a common point.

摘要： The invention contemplates a powder-feeding system for gas-propelled delivery of a powder to be controllably supplied, as to a flame-spraying gas torch or to a transferred-arc plasma torch. A fluidizing chamber receives (a) fluidizing-gas flow from below a porous screen, and (b) a restricted gravitational flow of powder at a relatively small central discharge location above the porous screen. A gas conduit extends transversely through the chamber between the powder-discharge location and the porous screen; it has a carrier-gas supply connection at one end and a gas-propelled powder-delivery connection at its other end. The conduit also has an upwardly extending opening virtually beneath and facing the powder-discharge location, but a shed interposed between this opening and the powder-discharge location sufficiently overlaps the opening to assure that no powder will pass through the opening and into the conduit unless it has been gas-fluidized. The powder-discharge flow is blocked to gas flow when powder is being delivered by the carrier-gas flow, but the powder delivery is terminated promptly upon gas-venting the fluidizing chamber, via the powder-discharge flow or otherwise.

Provision is made for optional use of one or more flame-shaping discharges of air, inert gas or the like at the discharge end, using a further independent supply system within the attachment.
