Description
Technical field
The present invention relates to field of powder metallurgy, particularly a kind of hard powder metallurgy alloy cutter and preparation method thereof.
Background technology
Powder metallurgy is to produce metal dust or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through shaping and sintering, produces metal material, composite and the industrial technology of all kinds goods.At present, PM technique has been widely used in the fields such as traffic, machinery, electronics, Aero-Space, weapons, biology, new forms of energy, information and nuclear industry, becomes one of branch of most development vitality in new material science.PM technique possesses the series of advantages such as the most energy-conservation, province's material, excellent performance, Product Precision height and good stability, is very suitable for producing in enormous quantities.The cutting tool performance of PM HSS manufacture is better than common high-speed steel, service life is higher than common high-speed steel (general 2～3 times), at the most alternative carbide tool of cutting occasion that impact load is big, therefore PM HSS cutter is the most good in the application prospect of tool industry, is increasingly paid close attention to by people.Compared with common high-speed steel tool, PM HSS cutter hardness is higher, toughness more preferable, more resistant to abrasion, therefore in some application (such as high impact-resistant, the processing occasion of big resection), PM HSS cutter has the trend gradually replacing relatively big, the most chipping under the cutting-impact solid carbide of fragility.
Summary of the invention
It is an object of the invention to provide a kind of hard powder metallurgy alloy cutter and preparation method thereof.
In order to realize the purpose of the present invention, the present invention is implemented by below scheme:
A kind of hard powder metallurgy alloy cutter, is prepared by the raw materials in: carborundum 30-32, titanium carbide 6-7, aluminum 2-3, silicon 1-2, chromium 9-10, ferrum 8-10, vanadium 3-4, Graphene 2-3, Nb2O53-4, manganese oxide 4-5, lithium carbonate 2-3, chlorinated paraffin 2-3, dispersion phase 3-4；
