Abstract
The invention relates to a wear-resistant aluminum alloy and a preparation method thereof. The wear-resistant aluminum alloy comprises an aluminum alloy substrate and a wear-resistant coating coated on the surface of the aluminum alloy substrate. The wear-resistant coating includes an Al / Ni primer layer coated on the aluminum alloy substrate, and The metal-ceramic composite coating on the primer layer; the Al / Ni primer layer is composed of the following mass percentage components: Al 2-8%, and the balance is Ni; the metal-ceramic composite coating is composed of the following mass percentage components: WC 10‑30%, the balance being Ni60. The wear-resistant aluminum alloy, the Al / Ni primer can improve the bonding performance of the metal-ceramic composite coating and the substrate. The metal-ceramic composite coating is a WC-Ni-based material, which significantly improves the hardness and wear resistance of the aluminum alloy material. The application range of aluminum alloy products is improved.
Description
A kind of wear-resistant aluminum alloy and preparation method thereof technical field The invention belongs to the preparation field of molten state cladding material, be specifically related to a kind of wear-resistant aluminum alloy and preparation method thereof Law. Background technique With the development of modern industry, various mechanical equipments have higher and higher requirements for lightweight materials, aluminum and aluminum alloys Due to its low density, rich content and excellent physical and chemical properties, it is widely used in the aerospace industry. but Due to the low hardness and poor wear resistance of aluminum and its alloy materials, its application has been limited to a certain extent. The material consumption caused by the wear of the gold surface is huge, and it is crucial to explore to improve the surface hardness and wear resistance of aluminum alloy materials. Significance. SUMMARY OF THE INVENTION The object of the pres...
