Description
Technical field
The present invention relates to technical field of aluminum alloy technology, more particularly to a kind of aluminium alloy suitable for human body joint of artificial limb position.
Background technology
Artificial limb is always a frontier nature research topic of robotics and biomedical engineering field.Artificial limb is compensatory
Prominent achievement is achieved in terms of human body missing function.Disabled person accounts for 5% or so in China human mortality at present, extremity disabled persons
About 8,770,000 people, account for the 14.6% of disabled person's sum, wherein nearly 1,000,000 people needs to install artificial limb.It is related to field of prosthetic limbs
The research of project is constantly subjected to the great attention of national Ministry of Civil Affairs and China Disabled Federation.As national economy is quickly good for
Kang Fazhan and living standards of the people are continuously improved, and there is an urgent need to upgrading is optimized to prosthetic product.
Knee joint is the critical component in human body artificial limb, and kneed disk wall is relatively thin, disk bottom have four it is symmetrical convex
The position risen, overall wall thickness difference is bigger, and shaping is more difficult, so sotck thinkness, to being formed with considerable influence, blank is too thin,
In die forging, one-pass molding ability is poor, thicker at shaping rear disk when blank is too thick, is easy to cause forge weight increasing.This
Outside, it is more satisfactory using stock of square rounded corner effect for blank shape, but positioning accurate is had in stock of square requirement
Standard, during concrete practice, causes forging forming bad, or forge other shapes due to being extremely difficult to be accurately positioned
The product of shape, therefore the present invention selects circular blank.
In order to improve kneed service life in artificial limb, the present invention provides one kind to be suitable for human body joint of artificial limb position
Aluminium alloy.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of aluminium suitable for human body joint of artificial limb position
Alloy.
Technical scheme is as follows：
A kind of aluminium alloy suitable for human body joint of artificial limb position, includes the component of following percentage by weight：Iron：0.1~0.4%、
Chromium：0.1 ~ 0.6%, gallium：0.2 ~ 0.7%, cobalt：0.1 ~ 0.5%, boron：0.1 ~ 0.5%, cerium：0.1 ~ 0.14%, lithium 0.08 ~ 0.35%, remaining
Measure as aluminium.
Preferably, the aluminium alloy suitable for human body joint of artificial limb position, includes the component of following percentage by weight：
Iron：0.2 ~ 0.3%, chromium：0.2 ~ 0.4%, gallium：0.3 ~ 0.5%, cobalt：0.3 ~ 0.4%, boron：0.25 ~ 0.4%, cerium：0.1 ~ 0.14%, lithium
0.12 ~ 0.25%, surplus is aluminium.
Preferably, zinc in aluminium alloy constituent content≤0.1%.
Preferably, silicon out of aluminium alloy content≤0.005%.
The invention has the beneficial effects that：Aluminium alloy prepared by the present invention, excellent performance, not only has well corrosion-resistant
Performance and plasticity, and be adapted to produce in enormous quantities, high precision machining does not crack, high in machining efficiency, is human body joint of artificial limb portion
Position provides extraordinary material selection.
