Nouel high-strength wear-resisting and corrosion-resisting aluminium alloy

Abstract

The invention relates to a new type strong antifriction anticorrosion aluminum alloy and the method to manufacture that belongs to metal material field. The weight ratio of the constituents is Si 1.0-50%, Fe 0.5-10.0%, Cu 0.1-5.0%, Mg 0.01-5.0%, La 0.01-3.0%, Ce 0.01-3.0% and the rest is Al. The manufacturing method is that: mixing the simple metal substance Al, Si, Fe, Cu, Mg, La, Ce according to the ratio, spraying settling to AlSiFeCuMgLaCe alloy rotundity ingot on the spraying molding device. The alloy rotundity could be processed to molding mechanism components. It could be widely used in motorcar, mechanism, metallurgy, and electric. The combination property is improved.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a high-silicon AlSi alloy and a preparation method thereof. Background technique [0002] At present, wear-resistant and corrosion-resistant aluminum alloys are all produced by melting casting or powder metallurgy. The materials produced by traditional melting and casting techniques and processes have problems such as coarse grain structure, composition segregation, and unstable performance; and powder metallurgy technology processes There is an insoluble oxide film on the particle boundary, which leads to the inability to eliminate the internal defects of the material and poor material performance. At the same time, the powder metallurgy processing process is complicated and the material yield is low. Therefore, spray forming technology provides an effective way for the development and production of new aluminum alloys. [0003] Metal atomization spray forming technology is a new...
