Abstract
The present invention provides a kind of powder metallurgy process, and by weight containing micro mist wax 5.8%, polyethylene 7.1 8.2%, cutting agent 3.1 4.2%, antiwear additive 1.3%, tungsten 3%, remaining is aluminium and is difficult to the impurity removed；Above-mentioned dispensing carries out die casting, deburring, obtains finished product afterwards by being mixed in the whipping process under 210~230 DEG C of high temperature with mixer.The present invention substantially increases the tensile strength and hardness of product.
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 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 turns into 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 turns into across more
The modern complex art of subject.Existing powdered metallurgical material low intensity.
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, to overcome lacking for low intensity in the prior art
Fall into.
(2) technical scheme
To solve the technical problem, the present invention provides a kind of powder metallurgy process, contains micro mist wax by weight
5.8%th, polyethylene 7.1-8.2%, cutting agent 3.1-4.2%, antiwear additive 1.3%, tungsten 3%, remaining is aluminium and is difficult to what is removed
Impurity；Above-mentioned dispensing carries out die casting, unhairing afterwards by being mixed in the whipping process under 210~230 DEG C of high temperature with mixer
Thorn, obtains finished product.
Further, the polyethylene weight ratio is 8%.
Further, the cutting agent weight ratio is 4%.
(3) beneficial effect
The powder metallurgy process of the present invention, substantially increase the tensile strength and hardness of product.
Embodiment
With reference to embodiment, the embodiment of the present invention is described in further detail.Following examples 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 micro mist wax 5.8%, polyethylene 7.1-8.2%, cutting
Agent 3.1-4.2%, antiwear additive 1.3%, tungsten 3%, remaining is aluminium and is difficult to the impurity removed；Above-mentioned dispensing passes through 210~230
Mixed under DEG C high temperature in whipping process with mixer, carry out die casting, deburring afterwards, obtain finished product.
The polyethylene weight ratio is 8%.The cutting agent weight ratio is 4%.
The powder metallurgy process of the present invention, substantially increase the tensile strength and hardness of product.
In summary, the restricted embodiment that it is the present invention that above-mentioned 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.
