Publication number: 20100314467Abstract: A thermal spraying device includes an arrangement for generating a flame and an arrangement for injecting a powder into the flame, the flame-generating means including an end piece out of an outlet of which the flame is directed towards a substrate subjected to spraying, and the powder-injection arrangement includes a frame element that projects in the flame ejection direction from the end piece, that at least partly surrounds a flame zone extending from the end piece, and that presents an inner circumference that is larger than the inner circumference of the outlet, and at least one powder port for the introduction of a powder to the flame being arranged on the inner periphery of the frame element at a distance from the outlet of the end piece as seen in the flame ejection direction. There is provided at least one gas injection opening in the frame element, the gas injection opening being located between the outlet of the end piece and the at least one powder port as seen in the flame ejection direction.Type: ApplicationFiled: August 25, 2010Publication date: December 16, 2010Applicants: VOLVO AERO CORPORATION, Hogskolan Trollhattan/Uddevalla Inst. for TeknikInventors: Jan Wigren, Jimmy Johansson, Stefan Björklund, Isabelle Choquet

Patent number: 7557324Abstract: A thermal spraying method and device that includes a device (1,2) which generates a flame and a device (3) which injects a powder into the flame. The flame-generating device (1,2) includes an end piece (1) out of which the flame is directed towards a substrate subjected to spraying. The powder-injection device (3) includes a frame element (6) that is adapted to be attached to the end piece (1) and to project in the flame ejection direction from the end piece (1). The frame element (6) has a plurality of through-holes (9) extending through it and distributed circumferentially about the frame element (6) as well as at least two powder injection ports distributed about the frame element (6).Type: GrantFiled: September 18, 2003Date of Patent: July 7, 2009Assignee: Volvo Aero CorporationInventors: Per Nylen, Alice Boussagol, Roger Svensson, Gabriel Mora, Mats-Olov Hansson, Jan Wigren, Jimmy Johansson
