摘要： A plasma arc torch includes a housing having a nozzle at one end with a central orifice. An electrode extends into the orifice for producing a plasma arc. A port is disposed in the nozzle adjacent the orifice for injecting powder into the arc. The port includes an outlet, an inlet, and a reniform manifold extending therebetween for laterally distributing the powder about the nozzle orifice. In this way, the powder may be carried to the torch underwater and is distributed circumferentially about the plasma arc while simultaneously diffusing its carrier gas.

摘要： Described herein is a method for providing a clean edge at the interface of a portion of a substrate coated with a coating system and an adjacent portion of the substrate which is uncoated. The method includes the step of forming a zone of non-adherence on the substrate portion which is to be uncoated, prior to application of the coating system. The zone of non-adherence is adjacent the interface, so that the coating system will not adhere to the zone of non-adherence, but will adhere to the portion of the substrate which is to be coated with the coating system.

摘要： A local environmental cell for a welding spray gun includes an annular ring having a top surface and a bottom surface, wherein the annular ring is adapted for attachment to an outer perimeter of the spray gun; and a plurality of fluid passageways radially disposed about the annular ring having a plurality of openings in the bottom surface of the ring in fluid communication with a vacuum source for providing a vacuum thereto. The use of the local environmental cell permits deposition of local bond coats as well as minimizes the number of steps associated with welding repair processes. For example, the use of the local environmental cell permits welding and formation of a low oxide bond coat during the welding process, thereby eliminating the need for placing the substrate subsequent to a welding process in a separate spray cell to deposit the bond coating.
摘要翻译： 用于焊接喷枪的局部环境池包括具有顶表面和底表面的环形环，其中环形环适于附接到喷枪的外周边; 以及围绕所述环形环径向设置的多个流体通道，所述环形环在所述环的底表面中具有与真空源流体连通的多个开口，用于向其提供真空。 使用局部环境细胞允许沉积局部粘合涂层，并且最小化与焊接修复过程相关的步骤数量。 例如，使用局部环境细胞允许在焊接过程中焊接和形成低氧化物接合涂层，从而消除了在焊接过程之后将基底放置在单独的喷雾池中以沉积粘结涂层的需要。

摘要： Method of producing a profiled abradable coating on a substrate in which an abradable ceramic coating composition is applied to a substrate using direct-write technology, or plasma sprayed onto the substrate through a mask or by use of a narrow foot-print plasma gun. These methods of producing abradable coatings are performed in the absence of a grid.

摘要： A robotic machine includes a machine tool removably supported in a mount for following a programmable path over a workpiece. A calibration pointer includes a housing configured like the tool for being supported in the mount, and a laser is affixed in the housing for emitting a laser beam at the workpiece. In a method of operation, the laser beam is projected from the laser in a focused spot at the workpiece at an offset therefrom. The spot permits accurate programming of the machine without contacting the workpiece.
