Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for applying thermal spray of micro-plasma on a part of a base body like a compressor blade part of a gas turbine without masking. SOLUTION: The device 10 is equipped with a positive electrode 16, a negative electrode 18, and an arc generation device generating an electric arc between the positive electrode and the negative electrode. An arc gas emitter 14 jets inert gas through the electric arc. The electric arc can be operated so as to ionize the gas in order to generate a plasma gas flow 21. A powder injector 22 jets powder material into the plasma gas. A limited area of the compressor blade is coated by the powder material without masking. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: An apparatus for microplasma spray coating a portion of a turbine vane (72) without masking includes a microplasma gun (12) with an anode (16), cathode (18), and an arc generator for generating an electric arc between the anode (16) and cathode (18). An arc gas emitter injects gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream (21). A powder injector (22) injects powdered material into a plasma stream (21). A localized area of the turbine vane (72) is coated with the powdered material (34) without having to mask the turbine vane (72).

Abstract: A portable, hand-held microplasma spray coating apparatus comprises an anode (16), a cathode (18) and an arc gas emitter (14) disposed in a housing (13), and a powder feeding system (23), a cooling system (11) and a power source (17) connected to the apparatus. The powder feeding system (23), cooling system (11) and power source (17) are detachably mounted on a mobile platform. The microplasma spray apparatus can be transported to on-site locations in the field to facilitate quick repair work.

Abstract: COATING APPARATUS AND METHODS 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.
