摘要： A coating end effector may be carried by a robot. A plasma spray head is mounted by a joint to the end effector. A plurality of actuators couple the end effector and plasma spray head to provide articulation of the joint. The apparatus may be used to coat an airfoil cluster of a gas turbine engine. The coating may include passing the head between the airfoils.

摘要： A process for forming a dense abrading thermally insulating coating on a rotor shaft in a gas turbine engine is described. The process comprises fixturing the rotor shaft to allow it to rotate about its axis and plasma spraying the coating on the rotor shaft. The coating comprises a zirconia based ceramic top coat layer on a metallic bond coat.

摘要： Microspray apparatus and methods involve injecting powdered material into a plasma gas stream. The material comprises first and second component powders. The second powder is a majority by the weight of the powdered material. The first powder acts as a melting point depressant. The first and second powders may have similar compositions but with the first powder including a greater quantity of a melting point depressant element.

摘要： A method for repairing a workpiece includes the steps of providing an unstripped, coated workpiece comprising a surface having a localized damage site; masking the workpiece about the localized damage site; generating a microplasma stream; and applying a first powdered material to the localized damage site using the microplasma stream; and applying a second powdered material to the workpiece surface using the microplasma stream. Another method for repairing a workpiece includes the steps of providing an unstripped, coated workpiece comprising a surface having a localized damage site; generating a microplasma stream; applying without a maskant a powdered metal alloy to the damage site using the microplasma stream; and dimensionally restoring the workpiece.

摘要： A microplasma spray coating apparatus includes a microplasma apparatus with an anode, cathode, and an arc generator for generating an electric arc between the anode and cathode. An arc gas emitter injects inert gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream. A powder injector nozzle extends through the anode and injects powdered material into the plasma stream for transfer to the workpiece.
