Abstract

The invention discloses a coating and a manufacturing method for an aluminum alloy wheel hub, and a method for compounding the coating on the wheel hub, including Al-Cu-Ag-Zn powder, aluminum alloy powder, Ni-SiC powder and organic Binder; the preparation method is to mix Al-Cu-Ag-Zn powder, aluminum alloy powder and Ni-SiC powder, add an organic binder to mix, and then repeatedly roll to obtain a coating; when compounding, it is The coating is attached to the surface of the pretreated hub, and the brazing reaction is carried out. The coating of the present invention is a flexible fibrous metal material, not only has uniform and dense composition, but also the metal fibers in the coating form a criss-cross three-dimensional spider web structure, and the preparation method is simple, safe and environmentally friendly; at the same time, it is compatible with aluminum alloy wheels Composite, excellent forming effect, high bonding strength, can effectively improve the wear resistance and hardness of the hub surface.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a coating and a manufacturing method for an aluminum alloy wheel hub, and a method for compounding the coating on the wheel hub. Background technique [0002] Common car wheels include steel wheels and aluminum alloy wheels. Steel wheels have high strength and are often used in large trucks. They are heavy and have a single shape. They do not conform to the current low-carbon and fashionable concepts, and are gradually being replaced by aluminum alloy wheels. Aluminum alloy wheels have the advantages of elegant appearance, light weight and fuel saving, high expansion rate, good elasticity, fast heat dissipation, etc., and they have good rigidity, good roundness, not easy to deform, and the wear of each part of the car is small, suitable for high-speed driving. The durability of the hub is slightly poor. Once it is deformed after encountering a hard object, it is di...
