Description
Technical field
The present invention relates to a kind of iron-based self-lubricating wear-resistant alloy and preparation method thereof.
Background technology
Along with science and technology development, fields such as modern industry manufacturing, aerospace, nuclear power and military affairs have all proposed increasing active demand to the high temperature lubricating problem under atmosphere and the particular surroundings.The engineering materials that uses as the tribology parts under the high temperature will be worked under rugged environment and tribology condition, and high temperature oxidation, high friction and serious wearing and tearing can cause the very fast inefficacy of engineering materials.In industrial production fields such as metallurgy, the energy, building materials and petrochemical compleies, exist high temperature, at a high speed, heavy duty and abominable working condition and Working environment such as high dust.Lost efficacy owing to be difficult to oil injecting lubricating or lubricating grease, and made mechanical means difficult in maintenance, often caused tribology component failures such as bearing, and caused production unit damage, production process to interrupt, even cause industrial accident.Studies show that owing to be subjected to the puzzlement of high temperature lubricating problem, from the machinery and the tribology over-all properties of material, alternative ready-made material is also very limited.Therefore, pressing for exploitation can resist high-temperature severe environment and the novel friction reducing abrasion resistant material of tribology condition destructive and inquire into new lubricating method.
Utilize the chalcogen compound of transiting group metal elements (to comprise sulfide, selenide and telluride, as MoS
2, WS
2And NbSe
2Deng) low rubbing characteristics realize effectively lubricating, the method that prepare self-lubricating material is known, and employing in practice.Wherein, adding active element S or Se in iron-based and nickel-base alloy, form the compound of some alloying element and S or Se element selectively and make alloy have the anti-friction wear-resistant self-lubricating property, is a kind of effective ways of preparation high temperature self-lubricating abrasion-proof material.
US 3,825, and 416 disclose at least a alloying element among Ti, Zr, V, Nb, Ta, Mo and the W that a kind of chemical ingredients (massfraction, down together) is a total amount 5～30%, 0.5～5%S or Se, and surplus is the self-lubricating ferrous alloy of Fe.And point out: reducing of frictional coefficient obviously is owing to formed the compound of nonferrous alloy element and S or Se element in the alloy.So the amount of S that adds in the alloy or Se element should adapt with the amount of nonferrous alloy element.
CN 1082620A, CN 10513370C and CN1360075 etc. disclose addition element S or Se in nickel-base alloy respectively, self-lubricating nickel-chromium alloy, sulfur contained high temoperature self lubricating nickel base alloy and the self-lubricating Ni-base alloy with higher mechanical strength, thermotolerance and high-temperature oxidation resistance and good self-lubricating property of development, exploitation.
CN 1049015C discloses a kind of high-sulfur alloy steel of being made up of iron, carbon, sulphur and alloying element, " it is characterized in that wherein sulphur content is 0.5～11% ".But this patent does not all offer some clarification on the content of " high-sulfur alloy steel " other alloying elements (C as described in it, Mo or W, Mn) except that element S in specification sheets and claims, obviously exists to disclose inadequate significant deficiency.Also there is the notion mistake that " alloy " and " alloying element " are obscured in the statement of its claim 3 " method according to claim 2 is characterized in that the alloying element that is added can be respectively molybdenum alloy, tungstenalloy, manganese alloy ".
CN 118812A, CN 1271028A and CN 1278563A disclose " through the New-type wear-resistant alloy steel of anneal ", " chromium tungsten sulfide anti-attrition cast steel " and " solid self-lubricating wear-resisting alloy cast material " respectively, its common trait is: contain 0～3% element S that does not wait in the material, and adopt the melt casting preparation.
CN 1062029C discloses sulfur-bearing iron-based high temp self-lubricating wear-resisting alloy of developing at the tribology parts of high temperature mechanisms such as light high-efficiency heat engine and advanced propulsion system and preparation method thereof.Though, this alloy has higher mechanical strength, thermotolerance and high-temperature oxidation resistance, in 20～600 ℃ temperature range, has low friction, anti abrasive good self-lubricating property, and in patent working, obtained success, but, to metallurgy, the energy, the high temperature in industrial production such as building materials and petrochemical complex field, at a high speed, the easy consume tribology parts of working under the bad working environments such as heavily loaded and high dust (high-temperature bearing for example, axle sleeve, slide plate, sealing member and control valve etc.), the raw material (as pure iron and chromium metal etc.) that preparation is adopted is on the high side, and is bigger than normal than the content of expensive alloy element Mo in the prescription.In addition, the investment cast forming method cost of employing is also higher.Owing on the market chromium that a large amount of available steel scrap resources is different with alternative various carbon contents, price is starkly lower than chromium metal-iron intermediate phase alloy (extra low carbon ferrochromium, medium carbon ferrochrome, high carbon ferro-chrome) is arranged, adopts common sand casting forming method to replace the investment cast forming method to reduce cost significantly.Therefore, for reducing the manufacturing cost of material, the present invention improves CN1220320A by changing raw material, adjustment prescription and change preparation method etc.
Summary of the invention
An object of the present invention is the tribology parts such as high-temperature bearing, orienting sleeve, bearing shell, slide plate, sealing member and control valve of high temperature mechanisms such as the metal fever processor of in room temperature to 600 ℃ temperature range, working and high-temperature technology process for industrial production fields such as metallurgy, the energy, building materials and petrochemical compleies, a kind of have higher mechanical strength, thermotolerance and high-temperature oxidation resistance are provided, and in 20～600 ℃ of temperature ranges, present the iron-based self-lubricating wear-resistant alloy of low friction, wear-resistant good self-lubricating property.
