The invention discloses wear-resistant alkaline-corrosion-resistant aluminum alloy which comprises, by weight, 12-13% of silicon, 3-4.3% of magnesium, 1.2-2.7% of lithium, 0.3-0.35% of titanium, 0.4-0.6% of cobalt, 0.6-0.76% of cerium, 0.1-0.2% of ytterbium and the balance aluminum. The corrosion resistance, particularly the alkaline corrosion resistance of the aluminum alloy can be obviously improved, the corrosion rate is decreased from originally 0.027-0.03g/(m<2> h) to 0.01-0.012g/(m<2> h), and the hardness is increased from originally about 490 to about 540.
Description
Technical field
The invention belongs to field of aluminum alloys, be specifically related to a kind of wear, alkali resistant erosion aluminium alloy.
Background technology
Aluminum silicon alloy is a kind of common aluminium alloy, the variation of alumina silica ratio can make hardness produce very large impact, when following such as silicone content 7%, aluminum silicon alloy has good ductility, and silicone content is above behind the al-si eutectic point, the Silicon In Alloys particle obviously increases, the wear resistance of alloy also increases significantly, but there is the selective corrosion phenomenon owing to al-si eutectic during actual use, existing method is aluminum silicon alloy to be carried out electrochemical treatment keep silicon in the matrix with etch top layer aluminium, improving its solidity to corrosion, yet there is complicated operation in the method, the uppity problem of Disposal quality.
Summary of the invention
The objective of the invention is to solve the problem of existing aluminum silicon alloy corrosion-resistant, a kind of excellent corrosion resistant aluminum alloy that has is provided.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is as follows:
A kind of wear, alkali resistant erosion aluminium alloy, consist of by weight: silicon 12～13%, magnesium 3～4.3%, lithium 1.2～2.7%, titanium 0.3～0.35%, cobalt 0.4～0.6%, cerium 0.6～0.76%, ytterbium 0.1～0.2%, surplus are aluminium.
Further, described anticorodal consists of by weight: silicon 12%, magnesium 3%, lithium 1.2%, titanium 0.3%, cobalt 0.4%, cerium 0.6%, ytterbium 0.1%, surplus are aluminium.
Further, described anticorodal consists of by weight: silicon 12.5%, magnesium 3.7%, lithium 1.4%, titanium 0.34%, cobalt 0.5%, cerium 0.69%, ytterbium 0.13%, surplus are aluminium.
Further, described anticorodal consists of by weight: silicon 13%, magnesium 4.3%, lithium 2.7%, titanium 0.35%, cobalt 0.6%, cerium 0.76%, ytterbium 0.2%, surplus are aluminium
Beneficial effect: adopt composition of the present invention, can significantly improve the solidity to corrosion of silumin, caustic corrosion resistance, erosion rate is by original 0.027～0.03g/ (m
2H) be down to 0.01～0.012g/ (m
