Technical Field

The invention relates to the field of metals, in particular to a high-strength powder metallurgy metal.

Background

Powder metallurgy is a process technique for producing metal powder or metal powder (or a mixture of metal powder and nonmetal powder) as a raw material, and then forming and sintering the raw material to produce metal materials, composite materials and various products. The powder metallurgy method has similar places to the production of ceramics and belongs to the powder sintering technology, so a series of new powder metallurgy technologies can also be used for preparing ceramic materials. Due to the advantages of the powder metallurgy technology, the powder metallurgy technology becomes a key for solving the problem of new materials, and plays a significant role in the development of the new materials.

Powder metallurgy includes milling and articles. Wherein the powder making is mainly a metallurgical process and is consistent with the word. Powder metallurgy products are often far beyond the scope of materials and metallurgy, often being a technology spanning multiple disciplines (materials and metallurgy, machinery and mechanics, etc.). Especially, modern 3D printing of metal powder integrates mechanical engineering, CAD (computer aided design), reverse engineering technology, layered manufacturing technology, numerical control technology, material science and laser technology, so that the powder metallurgy product technology becomes a modern comprehensive technology spanning more subjects;

however, the prior art still has the problems that the metal strength is too low in the actual use process, and the metal strength is difficult to be used for producing high-strength components and parts.

Disclosure of Invention

Therefore, in order to solve the problems, the invention provides a high-strength powder metallurgy metal which solves the technical problems that the metal strength is too low and the metal strength is difficult to be used for producing high-strength parts and components in the actual use process in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a high-strength powder metallurgy metal is prepared from the following raw materials in parts by weight: the feed is prepared from the following raw materials in parts by weight: tungsten carbide 1.5-2, Cr₁₂1.4 to 1.6 percent of vanadium, 1.0 to 1.4 percent of vanadium, 3.5 to 4.0 percent of molybdenum, 0.8 to 1.2 percent of carbon and the balance of iron, wherein the total amount of the components is 100 percent;

further, the proportion of the components in the total weight is 1.8 parts of tungsten carbide and Cr₁₂1.5, vanadium 1.2, molybdenum 3.6, carbon 1, iron 90.9.

By adopting the technical scheme, the invention has the beneficial effects that: the high-strength powder metallurgy metal improves the condition that the metal strength is too low in the actual use process in the prior art and is difficult to be used for producing high-strength parts and parts, the strength of a product made of the alloy can reach 200 Mpa-230 Mpa, for example, when the high-strength powder metallurgy metal is used for producing seedling needles of a rice transplanter, the service life of the seedling needles made of the alloy can reach several times to several tens times of the service life of common stainless steel seedling needles, and the high-strength powder metallurgy metal is suitable for the field with higher requirements on strength and wear resistance.
