Abstract
A high-Al Zn-base alloy suitable for antiwear parts contains Al (27-35 wt.%), Cu (1-3 wt.%), Mg (0.01-0.03 wt.%), one of Ti, Ti+B and Si+Re, and Zn (the rest). The advantage is high antiwear performance.
Description
The invention belongs to Zinc-base high-aluminium alloy metallurgical casting field, be used for the material of alloy-steel casting, make the Zinc-base high-aluminium alloy foundry goods.This material is mainly used in the production wear part, as bearing shell, axle sleeve etc.
Zinc-base high-aluminium alloy originates from developed country at the seventies, and China begins to adopt in the eighties.The present invention is on former general trade mark ZA27 aluminium zinc basis, the result who further develops.ZA27 aluminium zinc commonly used generally is used to produce wear parts such as lining tile, worm gear in China, in use often finds problems such as the life-span is lower, and example is as follows:
1. example 1: Benxi factory once manufactured experimently the wear-resisting lining tile of 650 milling trains with the ZA27 aluminium zinc, but duration of service can not be lasting, after be forced to again change into and adopt copper alloy production.
2. example 2: Benxi factory adopts sand mold to produce ZA27 aluminium zinc screw, and its product grains is thick, unit elongation is low, and the life-span is very short.
3. routine 3:97 Benxi factory adopts the ZA27 aluminium zinc to produce worm gear, finds when worm gear is tested on stand the machine oil blackening to illustrate that the ZA27 worm gear has been ground to due to the powder, can not drop into practicality.
The object of the present invention is to provide a kind of Zinc-base high-aluminium alloy, it has remedied the deficiency of former ZA27 aluminium zinc, improved the work-ing life of wear part, the range of application of Zinc-base high-aluminium alloy is enlarged, be applicable to more and make various wear parts, compare with copper alloy, not only can make pts wt reduction by 40%, unit weight price also reduce by 40%.Save valuable copper resource (China is the weary state of copper resource feedback), thereby can improve manufactory and user's economic benefit and social benefit.
Zinc-base high-aluminium alloy of the present invention, the chemical ingredients (weight %) that it is characterized in that it is as follows: Al:27-35, Cu:1.0-3.0, Mg:0.01-0.03, other alterant compositions be among Ti, Ti+B or the Si+Re any one, surplus is Zn, Ti:0.02-0.10 wherein, B:0.01-0.10, Si:0.02-0.10, Re:0.02-0.10.
The present invention is a ZA30C series Zinc-base high-aluminium alloy, and wherein Z represents that zinc, A represent that basic content, the C of aluminium, 30 expression aluminium represent the modified alloy element.One of its main contents are on former ZA27 aluminium zinc basis, have increased the content of aluminium.Aluminium is the main alloy element in the alloy, forms aluminium base sosoloid in alloy, has strengthened alloy substrate.Improve Al and can increase material monolithic intensity, hardness also improves.This Zinc-base high-aluminium alloy may be summarized to be following several types, and is as shown in table 1.
3 kinds of main types of table 1 ZA30C series Zinc-base high-aluminium alloy series alloy

Two of technological core of the present invention is in ZA30C series Zinc-base high-aluminium alloy, has adopted elements such as Si, Ti, B, Re as alterant.
Adopt alterant to be meant in common alloy melting, except that adding conventional ingredient, add oligo-elements in addition its process of setting is changed to some extent, reach the purpose of improving alloy property, and this process is referred to as rotten the processing.Its action principle is owing to added alterant, forms more external core, makes grain refining or changes crystal habit, thereby improve mechanical property.The metamorphic mechanism of used several alloying elements is as follows among the present invention:
1. alterant Ti (titanium)
Titanium mainly can form external crystallization nuclei, crystal grain thinning in alloy.Make the densification of foundry goods alloy structure, global tissue be tending towards evenly having improved hardness, wear resistance.
2. alterant B (boron)
Boron can suppress dendrite in ZA30C series Zinc-base high-aluminium alloy, make the alloy structure refinement, increases material plasticity, improves the unit elongation of material.
3. alterant Re (rare earth)
Rare earth can form multiple stable intermetallic compound in ZA30C series Zinc-base high-aluminium alloy, constitute the heterogeneous body core, makes the crystallization refinement, improves hardness, wear resistance and minimizing segregation.
4. alterant Si (silicon)
Silicon is that the form with rare earth alloy joins in the aluminium zinc, and solubleness is very little, mostly is independent existence, can improve the anti-binding property of wearing piece, wear resistance.
The basic production technology of ZA30C series Zinc-base high-aluminium alloy of the present invention is: casting mold manufacturing, alloy melting and casting.
Compared with prior art, advantage of the present invention and effect are as follows:
ZA30C series Zinc-base high-aluminium alloy is compared with ZA27 aluminium zinc commonly used, and mechanical property and use properties all increase, and also obtained prolongation work-ing life, is beneficial to save resources and energy.But ZA30C series Zinc-base high-aluminium alloy Alloy instead of Copper alloy production part foundry goods has been saved valuable copper resource (China is the weary state of copper resource feedback) simultaneously.Adopt ZA30C series Zinc-base high-aluminium alloy, reduced foundry goods cost, alleviated the weight of part, increased manufactory and user's economic benefit and social benefit.
(1) wearing piece of low load, middle low speed during former ZA27 can only the instead of part copper alloy produces.Low load, middle low speed wearing piece also were applicable to high-load in the Alloy instead of Copper alloy production during ZA30C series Zinc-base high-aluminium alloy not only can be used for, middle low speed, and tolerate certain ballistic wearing piece.
(2) ZA30C series Zinc-base high-aluminium alloy is compared tensile strength sigma with the aluminium zinc of the ZA27 that uses always
b, unit elongation δ, hardness HB all increase (as shown in table 2).Adopt the semi-cylinder lining tile in the ZA30C series Zinc-base high-aluminium alloy production milling train shaft coupling, but use the life-span to reach 5-6 month, and former copper alloy lining tile was only used about 2 months, had improved work-ing life more than 2 times.
