Abstract
The zinc-aluminium alloy material for artificial limb of the present invention is an artificial substitute for human body limb. In the invention, titanium and mixed rare earth trace elements are added into the ZA27 alloy, thereby improving the anti-aging capability of the ZA27 alloy. Meanwhile, the alloy has good crystal structure and mechanical property, and comprises the alloy components of Al26-28%, Cu1.5-2.5%, Mg0.07-0.15%, Ti0.10-0.25%, mixed rare earth RE0.10-0.15%, and the balance of Zn.
Compared with the common ZA27 alloy, the alloy has similar mechanical performance and greatly improved wear resistance and corrosion resistance. Compared with the stainless steel artificial limb material, the material has the characteristics of small mass, wear resistance and low cost, and is used for replacing stainless steel and titanium alloy for the artificial limb alloy material.
Description
The invention belongs to the pseudocolloid material, artificial surrogate of human body limb or substituent.
At present, the artificial limb alloy is mainly titanium alloy or stainless steel.Have advantages such as light weight, corrosion-resistant and comprehensive mechanical property be good with the artificial limb of titanium alloy production.But this alloy manufacturing cost height, cost an arm and a leg.Though stainless steel also can meet the demands on mechanical property as the artificial limb alloy, and its cost is low than titanium alloy, and it is made troubles to the patient than great, and the patient is difficult to accept.Therefore, development and exploitation have favorable comprehensive mechanical property, and the novel artificial limb alloy corrosion-resistant, that proportion is little, cost is low has realistic meaning.
ZA 27 alloy is a kind of novel casting alloy.It has that proportion is little, fusing point is low and advantage such as comprehensive mechanical property is good, is a kind of good engineering materials.Particularly its good wear resistance makes this alloy obtain good economic benefit aspect the replacement tinbronze.Yet, because zinc base alloy easily produces intergranular corrosion, produce " wear out " phenomenon, promptly mechanical property and dimensional stability in time continuity and reduce, cause the cracking of foundry goods in the time of seriously, the application of zinc base alloy is restricted.Especially in humid atmosphere, " wearing out " phenomenon is even more serious.Be to postpone " wear out " phenomenon, numerous scholars once carried out excessive quantity research, found that magnesium is one of element of " wearing out " of delay zinc base alloy.But because the magnesium add-on crosses conference and bring red brittleness, and observes according to us, magniferous ZA 27 alloy still has " wear out " phenomenon for a long time in humid atmosphere, do not have the problem of solution at all so aluminium zinc " wearing out " remains one.This problem becomes the big obstacle of ZA 27 alloy as prosthetic material.
The objective of the invention is to overcome " wearing out " problem of zinc-aluminium (ZA27) alloy, develop have good comprehensive mechanical properties, quality is little, does not have catabiosis, novel artificial limb alloy material that cost is low.
Content of the present invention is to add titanium and mishmetal trace element in ZA 27 alloy simultaneously, it is anti-to improve ZA 27 alloy: aging " ability; make it have good crystalline structure and mechanical property simultaneously, replace titanium alloy and stainless steel fabrication portion artificial limb component with this alloy.
The present invention improves the solidity to corrosion of ZA 27 alloy by adding rare earth and titanium, thereby solves " wearing out " problem of ZA 27 alloy effectively.Simultaneously, rare earth and titanium can also make the grain refining of aluminium zinc, and the secondary arm spacing of dendrite is reduced, thereby improve the mechanical property of ZA 27 alloy significantly, make its satisfied requirement as the pseudocolloid material.On the basis of experiment, determine that the chemical ingredients of ZA27 pseudocolloid alloy is (seeing Table 1):

This novel ZA 27 alloy is compared with common ZA 27 alloy, and its mechanical property, wear resisting property, corrosion resisting property are listed in table 2 respectively to table 4.These data show that novel ZA 27 alloy is compared with common ZA 27 alloy, and mechanical property is close, and wear resisting property and corrosion resisting property are improved largely.

Novel ZA 27 alloy is compared more water-fast steam corrosion (seeing Table 5) as the pseudocolloid material with titanium alloy pseudocolloid material (TA7), compare the advantage (seeing Table 6) with light weight with stainless steel pseudocolloid material (R45).Wear resistance that particularly this alloy is good and low cost (not enough titanium alloy 1/10th), the good material that this alloy is become substitute stainless steel and titanium alloy to be produced as pseudocolloid.
The part pseudocolloid part that the present invention produces is seen accompanying drawing 1, and its chemical ingredients is for containing aluminium

26.5%, copper 1.95%, magnesium 0.09%, titanium 0.20%, mishmetal 0.13%, surplus is a zinc.Wherein mishmetal comprises any single rare earth element, can improve anti-" wearing out " property of aluminium zinc.
With the pseudocolloid that this alloy is made, to install to try out and go through 7 months long run test, service condition is good, and the artificial limb spare of producing with this ZA 27 alloy has caused domestic colleague's concern.
Facts have proved that this alloy can satisfy as the pseudocolloid material requirements on performance, and production technique simple, with low cost, have titanium alloy and the incomparable advantage of stainless steel, therefore, this material has good prospects for application.
