Abstract
The present invention provides a kind of powder metallurgy process, and by weight containing ceramic powders 1.9%, Zirconium oxide powder 2.1 3.9%, ferroalloy powder 1.1 1.2%, molybdenum powder 3.3%, zinc stearate 2.1%, rhodium powder 0.6%, remaining is iron powder and is difficult to the impurity removed；Above-mentioned powder is sufficiently mixed, and is carried out mixing compacting afterwards, die casting, post processing, is obtained finished product.The present invention improves the wearability and intensity of manufactured gear.
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 wears no resistance.
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 what is worn no resistance in the prior art to lack
Fall into.
(2) technical scheme
To solve the technical problem, the present invention provides a kind of powder metallurgy process, contains ceramic powders by weight
1.9%th, Zirconium oxide powder 2.1-3.9%, ferroalloy powder 1.1-1.2%, molybdenum powder 3.3%, zinc stearate 2.1%, rhodium powder
0.6%, remaining is iron powder and is difficult to the impurity removed；Above-mentioned powder is sufficiently mixed, and carries out mixing compacting, die casting, rear place afterwards
Reason, obtains finished product.
Further, the Zirconium oxide powder weight ratio is 3%.
Further, the ferroalloy powder weight ratio is 1.2%.
(3) beneficial effect
The powder metallurgy process of the present invention, improve the wearability and intensity of manufactured gear.
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 ceramic powders 1.9%, Zirconium oxide powder 2.1-
3.9%th, ferroalloy powder 1.1-1.2%, molybdenum powder 3.3%, zinc stearate 2.1%, rhodium powder 0.6%, remaining is iron powder and is difficult to
The impurity of removal；Above-mentioned powder is sufficiently mixed, and is carried out mixing compacting afterwards, die casting, post processing, is obtained finished product.
The Zirconium oxide powder weight ratio is 3%.The ferroalloy powder weight ratio is 1.2%.
The powder metallurgy process of the present invention, improve the wearability and intensity of manufactured gear.
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.
