Abstract:

A method of coating a vehicle wheel to increase wear and corrosion resistance of the vehicle wheel, includes the steps of providing a vehicle wheel and applying a wear and corrosion resistant coating onto a surface of the vehicle wheel. The coating is applied to at least a tire bead retaining flange of the vehicle wheel. The coating is of particular use with vehicle wheels made of forged aluminum. The coating is selected from tungsten carbide, optionally including cobalt or chrome, a nickel-based superalloy, aluminum and silicon carbide, or stainless steel. The coating is typically applied to a thickness of about 0. 004-0. 01 inch. The surface of the vehicle wheel may be prepared by mechanically abrading the surface or chemically etching the surface of the vehicle wheel. The coating may be applied by cold spraying, thermal spraying, or triboelectric discharge kinetic spraying and other similar processes.

International Classification:

B23K 1/20
B23K 35/12

US Classification:

228246, 228 563

Abstract:

A braze ring includes a generally annular body and an outer annular channel formed on an outer surface of the body. A method of connecting a straight tubular end to a flared tubular end includes locating a substantially annular braze ring substantially concentrically around the straight tubular end, inserting the straight tubular end into the flared tubular end so that the braze ring engages the flared tubular end, and heating the braze ring so that flux separates from an exterior channel of the braze ring and the separated flux from the exterior channel contacts at least one of a faying surface of the flared tubular end and a faying surface of the straight tubular end. Another braze ring includes a body having a substantially symmetric cross-sectional shape forming an inner channel and an outer channel and flux carried within each of the inner channel and the outer channel.

International Classification:

B32B 1500

US Classification:

428654

Abstract:

A composite metallurgical product includes a roll cast aluminum alloy core and a filler material bonded on the core. Assemblies joined by filler material are formed from this product by heating to flow the filler material into joints and subsequent solidification of the filler material in the joints. The composite product is made in several ways, including lamination at roll caster rolls, and lamination or thermal spraying at the exit side of a roll caster. The invention additionally provides for an angulation rolling method for varying percent of cladding on the composite, and a high-manganese aluminum alloy useful as core material in brazing sheet clad with aluminum-silicon brazing alloy.

International Classification:

B21B 146

US Classification:

295272

Abstract:

A friction-wear aluminum part which includes a metal substrate and friction-wear coating applied to at least a portion of the outer surface to said substrate. The coating is a mixture of both aluminum and stainless steel. On a preferred basis, the surface of the substrate is intentionally roughened or grooved to facilitate bonding of the coating thereto. An associated method is also disclosed.

International Classification:

G03C 1492

US Classification:

430278

Abstract:

An essentially flat "arc-grained" surface of a sheet of aluminum alloy is produced with a coarse and non-uniform microstructure which, after it is coated with a durable phosphate-free coating, provides excellent lithoplate. Though such arc-grained microstructure is much coarser than an electrochemically etched surface typically used on lithoplate, the very coarse surface is peculiarly well-adapted to provide durable lithoplate after it is coated with a phosphate-free protective surface. After the coated surface is coated with a photoresist the excellent resolution of prints is maintained over a large number of repeated uses in an off-set printing press. A method of producing lithoplate comprises, controlledly rastering an A-C, or D-C reverse polarity plasma-generating electric arc on an aluminum sheet less than 30 mils thick, kept distortion-free on a mounted surface such as on a cylindrical drum; then coating the arc-grained surface with a hard and durable, inert phosphate-free coating while maintaining a capillary microstructure in the surface adapted to provide a support for a photoresist for use in lithographic printing of adequate resolution.
