Abstract
The invention relates to a technology of injecting tungsten carbide gradient materials to seamless steel tube guide board. The invention feeds inert gas at low vaccum condition, and forms energetic tungsten ion and inert gas ion under abnormal glow discharge condition. It comprises following steps: treating seamless steel tube guide board with nitrogen, injecting tungsten ion into surface of said guide board at a certain temperature, then carbonizing tungsten; or treating seamless steel tube guide board with nitrogen firstly, then injecting tungsten ion and carbon ion together. The tungsten carbide alloy with certain of depth is formed on the surface of guide board, which increases the hardness of metal surface and improves the wear resistance, high temperature resistance and self lubricating property. The product is characterized by high ptemperature resistance, high hardness, high strength, high wear resistance and corrosion resistance, and increased life length.
Description
Technical field
The present invention relates to a kind of steel matrix energetic ion and inject wolfram varbide (WC) gradient material manufacturing technology, particularly a kind of super wear-resistant alloy layer of metal material surface that is applied to prepares in the industry, utilize different kinds of ions source, plasma source generation equipment, in specific environment, at the superior super wear-resistant alloy layer of the surface preparation application performance of steel as matrix material, the manufacturing technology of carbon tungsten alloy is rich in the metallic surface that can satisfy advanced metal surface modification requirement.
Background technology
In modern development in science and technology and industrial production, a lot of visual plants and component thereof are under the abominable working conditions, as high speed, high temperature, high pressure, heavy duty and high potential of hydrogen.The destructive process of forms such as the wearing and tearing of metal parts, burn into oxidation is also in acceleration, and wearing quality just becomes one of limiting element of developping production, reducing cost.According to the authoritative department statistics, about 75% belongs to galling in the component of machine that lost efficacy, and galling also can cause the mechanical means running efficiency to reduce, and workpiece is changed or keep in repair frequent, and energy consumption increases.
Because friction, wearing and tearing and corrosion cause the damage of equipment component, mostly from the surface, it is impaired to adopt the interface safeguard procedures to delay with control surface, becomes the effective ways that improve the component wearing quality.So various surperficial abrasionproof engineerings are arisen at the historic moment, technology such as coating, hot plating, thermospray, built-up welding, plated film and high energy beam are maked rapid progress.The various surface wear-resistant materials made from these technology, and Gao Meng, Gao Ge, rare earth antifriction cast iron (steel), cast stone, paste high-abrasive materials such as pottery, formed a high-abrasive material extended family, differ from one another, each shows wear-resisting remarkable ability, for scientific and technological and industrial production development are made contributions and started one's career.
But also there are a lot of congenital defects separately in they:
1. various antifriction cast irons (steel) all have the fundamental property of cast steel and iron, but hardness, intensity, toughness is on the low side, the wear resistance deficiency;
2. the cast stone material has certain wear resistance, and price is lower, but weight is too heavy, and impact resistance is poor, and the internal stress that easily happens suddenly malicious event is installed and can not on-site cutting and welding during maintenance;
3. thermospray, build-up wear-resistant layer, paste the formed stiff dough of ceramic layer, wear resistance is good, adapts to wide, but all with interface that bonding strength is on the low side of matrix existence, easily produce wearing layer at the interface at this and come off and lose the abrasionproof effect;
4. wear-resisting plated film, the deposited wearing layer of high energy beam adapts to wide, but the common wearing layer that exists is too thin, the too high problem of expense.
In this case, many clients that seek high-abrasive material urgently wish a kind of Eco-power senior high-abrasive material of postgraduate's output.The technical requirements that they propose is concluded five:
1. the wear resistance of new high-abrasive material is than common high-abrasive material height;
2. new high-abrasive material weight wants light, and wearing layer thickness again can not be too thin;
3. new high-abrasive material should possess high intensity, hardness, toughness and fatigue resistance simultaneously;
4. new high-abrasive material in use wearing layer can not cause abrasionproof to lose efficacy because of coming off, bursting apart;
5. new high-abrasive material should have reasonable price.
In the surface wear-resistant layer technology of preparing of using at present, reach almost not having of these five technical requirementss simultaneously.
Summary of the invention
The objective of the invention is to provides the ion implantation wolfram varbide of a kind of seamless steel pipe units guide plate high-energy (WC) gradient material manufacturing technology at above-mentioned prior art and the existing defective of equipment and deficiency.
Ultimate principle of the present invention is: by suitably charging into rare gas element under the rough vacuum situation, and under the anomalous glow discharge condition, form high energy tungsten ion and inert gas ion.After at first seamless steel pipe units guide plate being carried out the gas soft nitriding processing, then at a certain temperature that tungsten is ion implantation in the seamless steel pipe units guide plate matrix, again tungsten is carried out carbonizing treatment; After perhaps at first seamless steel pipe units guide plate being carried out the gas soft nitriding processing, the double ion high energy that carries out tungsten ion and carbon ion again injects.
The present invention can form carbon tungsten alloy layer certain depth, that change in gradient on the top layer of seamless steel pipe units guide plate, improve the hardness of metallic surface, has improved high temperature resistant, the wear resistance and the self lubricity of seamless steel pipe units guide plate.
Have high temperature resistant, high rigidity, high strength, high abrasion, advantage such as corrosion-resistant with the product of manufacturing of the present invention, and the work-ing life of having improved seamless steel pipe units guide plate significantly.
