Abstract

The invention provides an impact resistant composite metal material. The impact resistant composite metal material is characterized by containing, by weight, 0.8%-2.5% of carbon, 0.4%-1.5% of silicon, 1.2%-3.5% of chromium, 0.25%-0.8% of tin, 0.3%-0.7% of cobalt, 0.45%-1.2% of aluminum, 1%-5% of nickel, 0.5%-2.5% of copper and the balance iron and a small quantity of impurities. The impact resistant composite metal material is excellent in impact resistance, good in abrasion resistance and corrosion resistance and high in hardness and tenacity, the adaptability of the metal material to temperature difference is improved, and the quality of the metal material is improved.

Description

A kind of shock proof composite material

Technical field

The present invention relates to technical field of metal, be specifically related to a kind of shock proof composite material.

Background technology

We are often by two or more metallic element or be that base adds the metallic substance with metallic character that other non-metallic elements are formed by alloying technology (melting, mechanical alloying, sintering, vapour deposition etc.) and is called alloy with metal.But alloy only may contain a kind of metallic element, as steel.The generation of alloy often can improve the character of element simple substance, and such as, the intensity of steel is greater than its main component iron.The physical properties of alloy, such as density, reactivity, Young's modulus, electroconductibility and thermal conductivity may still have similar part with the component of alloy, but the tensile strength of alloy and slip resistance but usually and the character of component have a great difference.This is because the atomic arrangement in alloy and simple substance has very big-difference.Certain a small amount of element the character of alloy may cause very large impact.Such as, the impurity in ferromagnetic alloy can make the character of alloy change.The application of alloy relates to the every aspect in social life, as aluminum alloy doors and windows and stainless kitchen tools etc., alloy also by a large amount of for aerospace field, alloy as this in titanium alloy has that intensity is high, solidity to corrosion good, thermotolerance high is widely used in manufacturing aircraft engine compressor part, is secondly the structural part etc. of rocket, guided missile and high-speed aircraft.

But in the field that some are higher for the performance requriements of metallic substance, conventional metallic substance also cannot satisfy the demands far away.Therefore, for above problem, the present invention proposes a kind of new technical scheme.

Summary of the invention

The object of this invention is to provide a kind of wear resisting property good, the shock proof composite material that toughness is high.

The present invention is achieved through the following technical solutions:

A kind of shock proof composite material, is characterized in that: the raw material composition comprising following weight percent:

Carbon 0.8% ~ 2.5%;

Silicon 0.4% ~ 1.5%;

Chromium 1.2% ~ 3.5%;

Tin 0.25% ~ 0.8%;

Cobalt 0.3% ~ 0.7%;

Aluminium 0.45% ~ 1.2%;

Nickel 1% ~ 5%;

Copper 0.5% ~ 2.5%;

Surplus is iron and a small amount of impurity.

Further, the rare earth element that weight percent is 0.005% ~ 0.025% is also comprised.

Further, described rare earth element is lanthanum, yttrium, cerium one wherein.

Further, the niobium that weight percent is 0.01% ~ 0.05% is also comprised.

The invention has the beneficial effects as follows: material proposed by the invention to there is excellent shock resistance, simultaneously, wear resisting property is good, and hardness is high, and toughness is strong and resistance to corrosion good, and, improve the adaptability of metallic substance to the temperature difference, improve the quality of metallic substance.
