Abstract
The invention discloses a kind of steel alloy, the component of following mass percent is included：Iron 86 90%, copper facing TiB2‑Al2O3TiC composite granules 4 5%, zirconium 0.01 0.03%, tungsten carbide 3 4%, manganese 0.7 1.2%, rare earth 0.3 0.5%, molybdenum 0.8 1.0%, chromium-base alloy powder 1.0 1.5%, niobium 0.03 0.06%, phosphorus 0.03 0.05%, sulphur 0.02 0.03%, carbon 0.12 0.2%.The steel alloy of the present invention is using the improvement to composite granule, then is equipped with other compositions, is made up of the method for powder metallurgy so that obtained steel alloy has good impact resistance rate, heat-resisting quantity, wear resistance and corrosion resistance, and service life also has enhancing.
Description
Technical Field
The invention belongs to the field of powder metallurgy materials, and particularly relates to alloy steel.
Background
Powder metallurgy low alloy steels have high strength, high hardness and good ductility, are particularly suitable for being used as structural materials, and are therefore widely used in the defense industry and the civil industry, in particular in the automobile, motorcycle, firearm and household appliance industries. With the development of science and technology and the improvement of the requirements of people on the quality of products, the requirements on materials are higher and higher. In order to improve the performance of powder metallurgy alloy steel, researchers at home and abroad have conducted a great deal of research on the aspects of raw material preparation and forming technology, sintering method and the like of component design of alloy steel. On the basis of the existing research, through a plurality of component improvements and experiments, the invention provides the alloy steel which is prepared by copper plating of ceramic powder and matching with other metal powder, and the alloy steel has good impact resistance, high temperature resistance, wear resistance and corrosion resistance, and the service life is also prolonged.
Disclosure of Invention
