Tooling Fixture Assembly For Use In A Coating Operation

View page
US Patent:
20130149450, Jun 13, 2013
Filed:
Dec 7, 2012
Appl. No.:
13/707901
Inventors:
Albert Feuerstein - Carmel IN, US
Andrew Thomas Westfall - Brownsburg IN, US
David A. McPherson - Coatesville IN, US
Ardy Kleyman - Carmel IN, US
Don Lemen - Indianapolis IN, US
International Classification:
B05C 13/02
US Classification:
427282, 118500
Abstract:
A modular, rotisserie type tooling fixture assembly for use in a coating operation and method of its use are disclosed. The tooling fixture assembly includes an arbor or shaft and a retaining base with a plurality of anchor members disposed in a prescribed radial orientation from the center of the retaining base, the anchor members are uniquely configured or adapted to retain a plurality of workpieces to be coated. The tooling fixture assembly further comprises a unique workpiece masking arrangement that employs a unitary masking cap having a plurality of solid walls or surfaces adapted to cover portions of the plurality of workpieces in a masking relationship.

Reactive Gas Shroud Or Flame Sheath For Suspension Plasma Spray Processes

View page
US Patent:
20130156968, Jun 20, 2013
Filed:
Dec 14, 2012
Appl. No.:
13/715361
Inventors:
Christopher A. Petorak - Carmel IN, US
Don J. Lemen - Indianapolis IN, US
Albert Feuerstein - Carmel IN, US
International Classification:
C23C 4/12
US Classification:
427446, 239290
Abstract:
A system and method for producing thermal spray coatings on a substrate from a liquid suspension is disclosed. The disclosed system and method include a thermal spray torch for generating a plasma and a liquid suspension delivery subsystem for delivering a flow of liquid suspension with sub-micron particles to the plasma to produce a plasma effluent. The liquid suspension delivery subsystem comprises an injector or nozzle which can produce a reactive gas shroud surrounding the plasma effluent. A flame envelope can also be used to isolate injection of the liquid suspension. The shroud or flame envelope can retain the sub-micron particles entrained within the plasma effluent and substantially prevent entrainment of ambient gases into the plasma effluent. The liquid suspension delivery subsystem can be arranged as an axial injection system, a radial internal injection system or an external radial injection system.

System And Method For Utilization Of Shrouded Plasma Spray Or Shrouded Liquid Suspension Injection In Suspension Plasma Spray Processes

View page
US Patent:
20130157040, Jun 20, 2013
Filed:
Dec 14, 2012
Appl. No.:
13/715189
Inventors:
Christopher A. Petorak - Carmel IN, US
Don J. Lemen - Indianapolis IN, US
Albert Feuerstein - Carmel IN, US
Mark McCoy - Indianapolis IN, US
International Classification:
B05B 7/20
C23C 4/12
US Classification:
428323, 427446, 239290
Abstract:
A system and method for producing thermal spray coatings on a substrate from a liquid suspension is disclosed. The disclosed system and method include a thermal spray torch for generating a plasma and a liquid suspension delivery subsystem for delivering a flow of liquid suspension with sub-micron particles to the plasma to produce a plasma effluent. The liquid suspension delivery subsystem comprises an injector or nozzle which can produce an inert or reactive gas sheath partially or fully surrounding the plasma effluent. A sheath can also be used to isolate injection of the liquid suspension. A gas assist stream can also be employed at or near the suspension injection point. The shroud, sheath or gas assist technique can retain the sub-micron particles entrained within the plasma effluent and substantially prevent entrainment of ambient gases into the plasma effluent. The liquid suspension delivery subsystem can be arranged as an axial injection system, a radial internal injection system or an external radial injection system.

Don Lemen - Indianapolis IN, US
International Classification:
B05C 13/02
US Classification:
427282, 118500
Abstract:

Laminar Flow Shielding Of Fluid Jet

View page
US Patent:
54863830, Jan 23, 1996
Filed:
Aug 8, 1994
Appl. No.:
8/286200
Inventors:
Mark S. Nowotarski - Stamford CT
Don J. Lemen - Indianapolis IN
William J. Snyder - Ossining NY
David B. Leturno - Hoover AL
Assignee:
Praxair Technology, Inc. - Danbury CT
International Classification:
B05D 306
US Classification:
427446
Abstract:
A process and system for shielding a turbulent fluid stream, comprising emitting a laminar flow of a shielding gas transversely to the flow direction of the turbulent fluid stream preferably from a porous wall. The turbulent fluid stream may be hot and may contain a coating material. By projecting or directing the turbulent fluid stream at the surface of a substrate to be coated, the heated coating material is deposited on the surface of the substrate.
