Description
Technical field
The invention belongs to forging process field of lubricant in intermetallic composite coating, particularly rotate cold forging tungstenalloy lubricant compositions.
Background technology
Tungsten, a kind of Steel Grey or argenteous metallic element, belonging to non-ferrous metal, is also rare metal, is the grand strategy resource of country.Tungsten is typical rare metal.Hardness is high, and fusing point is high, not by air erosion under normal temperature; Main application is for manufacturing filament and high speed cutting steel alloy, superhard mould, and also for opticinstrument, purposes is very important.It is the important component part of contemporary high technology novel material, and a series of electron optics material, specific alloy, new function material and organometallic compound etc. all need the tungsten using special performance.Though consumption is little, most important, lacking it can not.Thus contemporary mechanics of communication, robot calculator, aerospace exploitation, medical and health, sensitive materials, photoelectric material, energy and material and catalystic material etc. are widely used in.Relate to mine, metallurgy, machinery, building, traffic, electronics, chemical industry, light industry, weaving, military project, space flight, science and technology, each industrial circle.The section bar that tungsten rotates cold forging requires higher for product surface quality, but work hardening phenomenon can be more serious.
Rotation cold forging is made: it is at room temperature, a kind of special process of production precision forging on swaging machine.In the cold forging process of rotation, the bar send to axial-rotation or materials in the tube apply radial impulse hitting power, billet cross section is reduced, is swaged into and has varying cross-section or uniform cross section forging along axle.Different by equipment, it can be divided into roller rotary swaging and the forging of radial precision fork machine.Rotary swaging has pulse heating and multidirectionally forges two features, and pulse-repetition is high, is generally 180 ~ 1800 times/min, and each deflection is very little.Therefore, tungsten metal deformation flow is apart from short, and friction resistance is little, and distortion evenly.Utilize many tups to forge from multiple directions, tungsten metal is out of shape being under three-dimensional compressive stress state, is conducive to the raising of tungsten Plastic Deformation.It is high that rotary swaging technique has forging quality, and production frequency is high, level of automation advantages of higher; Also there is device structure complexity simultaneously, difficult in maintenance, cost is high, specificity is strong, to the high deficiency of forging stock requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide that one has lubrication, cooling, perviousness, thermal oxidation stability can be excellent, dispersion, cleaning, infiltration, supporting capacity, anti-wiping, pull, draw trace ability strong, make that fabircated shapes surface smoothness is high, dimensional stabilizing, specification precision high, the anti-rotten cycle is long, be applicable to different fuel system, easy to operate rotation cold forging tungstenalloy lubricant compositions.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Rotate cold forging tungstenalloy lubricant compositions, adopt oil based on poly-alpha olefins, coordinate multiple additives, its each component and mass percent thereof are:
