Abstract
The present invention provides a kind of powder metallurgy process, and by weight containing lubricant 1.2%, copper 3.1 3.2%, zinc 3.2 4.1%, ethene 1.3%, additive 0.2%, remaining is aluminium and is difficult to the impurity removed, and above-mentioned raw material are carried out extruding crushing；Above-mentioned powder ingredients carry out die casting, reusable heat water is cleaned, antirust treatment, screening and drying afterwards by being stirred under 230~310 DEG C of high temperature.The present invention substantially reduces production cost, service life length, hardness height.
Description
Technical field
The present invention relates to a kind of powder metallurgy process.
Background technology
Powder metallurgy is to produce metal dust or made with metal dust (or mixture of metal dust and non-metal powder)
For raw material, by shaping and sintering, the technology of manufacture metal material, composite material and all kinds product.Powder smelting
Jin Fayu production ceramics have similar place, belong to sintered powder technique, therefore, a series of New Technologies In Powder Metallu Rgies also can use
In the preparation of ceramic material.The advantages of due to PM technique, it becomes the key for solving the problems, such as new material, in new material
Development in play very important effect.Powder metallurgy includes powder processed and product.Powder wherein processed is mainly metallurgical process, and word
Face coincide.And sintered metal product is then often far beyond material and metallurgical category, often across it is multidisciplinary (material and metallurgy,
Machinery and mechanics etc.) technology.Especially contemporary metal powder 3D printing [1-2], collection mechanical engineering, CAD, reverse Engineering Technology,
Layered Manufacturing Technology, Numeric Control Technology, material science, laser technology are so that sintered metal product technology becomes across more
The modern complex art of subject.Existing powdered metallurgical material manufacture is of high cost.
The content of the invention
(1) technical problems to be solved
The problem to be solved in the present invention is to provide a kind of powder metallurgy process, with overcome manufacture in the prior art it is of high cost
Defect.
(2) technical solution
To solve the technical problem, the present invention provides a kind of powder metallurgy process, contains lubricant by weight
1.2%th, copper 3.1-3.2%, zinc 3.2-4.1%, ethene 1.3%, additive 0.2%, remaining is aluminium and is difficult to the impurity removed,
Above-mentioned raw material are subjected to extruding crushing；Above-mentioned powder ingredients are carried out afterwards by being stirred under 230~310 DEG C of high temperature
Die casting, reusable heat water are cleaned, antirust treatment, screening and drying.
Further, the weight ratio of the copper is 3.2%.
Further, the weight ratio of the zinc is 4%.
(3) beneficial effect
The powder metallurgy process of the present invention, substantially reduces production cost, service life length, hardness height.
Embodiment
With reference to embodiment, the embodiment of the present invention is described in further detail.Following embodiments are used for
Illustrate the present invention, but be not limited to the scope of the present invention.
A kind of powder metallurgy process of the present invention, by weight containing lubricant 1.2%, copper 3.1-3.2%, zinc 3.2-
4.1%, ethene 1.3%, additive 0.2%, remaining is aluminium and is difficult to the impurity removed, and above-mentioned raw material are carried out extruding powder
It is broken；Above-mentioned powder ingredients carry out die casting by being stirred under 230~310 DEG C of high temperature afterwards, and reusable heat water is cleaned,
Antirust treatment, screening and drying.
The weight ratio of the copper is 3.2%.The weight ratio of the zinc is 4%.
The powder metallurgy process of the present invention, substantially reduces production cost, service life length, hardness height.
In conclusion the restricted embodiment that it is the present invention that the above embodiment, which is not, all those skilled in the art
The modification carried out on the basis of the substantive content of the present invention or equivalent deformation, the technology category in the present invention.
