Abstract
The present invention relates to a manufacturing material of engine cylinder, in particular, relates to engine cylinder made of steel-boded hard alloy material. The cylinder of engine is made of steel-bonded hard alloy with hard phase content of 30-50%. The steel-bonded hard alloy makes the cylinder of engine reduced or even need of heavy maintainence and elongate the servic life of engine for at least five years. Therefore, it can save raw material, improve and maintain the engine always under good working condition, save oil, reduce blow-off, raise environmental protection effect.
Description
Technical field
The present invention relates to motor, particularly the manufactured materials of motor cylinder barrel is specially the motor that cylinder barrel is made by the Steel Bond Hard Alloy material.
Background technique
During engine operation, cylinder barrel and piston ceaselessly rub, and cylinder barrel is the friction parts of engine core.Its cylinder barrel of existing motor is made with spheroidal graphite cast iron usually, long-time abrasion, can make cylinder barrel circularity and cylindricity become big, the variation that is upper diameter is bigger, the cylinder shoulder usually appears, when wearing and tearing aggravation sealability variation, oily phenomenon will appear being short of power or scurrying, must carry out boring cylinder and rering.Therefore, the wear resistance of engine friction parts, particularly cylinder barrel, the working life and the maintenance frequency of decision motor.With existing motor car engine is example, and overhaul in 3 years was just scrapped in 10 years substantially, and its working life is relatively low, and automobile is frequently scrapped, and causes great deal of steel and noble metal to become waste product, and the earth that the mankind are depended on for existence is the significant wastage of multiple resource.For improving the wear resistance of cylinder barrel, prior art adopts technological means such as cylinder barrel is surfaces nitrided, plating, laser hardening, to improve the wear resistance of cylinder barrel self.
The Steel Bond Hard Alloy material is a kind ofly to make Bond with steel, does the hard phase with carbide (titanium carbide or Tungsten carbite), a kind of known Hardmetal materials made from powder metallurgy process.Steel Bond Hard Alloy no matter from composition still from its characteristic, all we can say it between tool steel and ordinary rigid alloy, both had wear resistance (its hardness H of high hardness
RC32-64), have again than cemented carbide more superior toughness, cold and hot working and weldability, its wear resistance is tens times of general steel, and therefore, it is widely used on the products such as cutter, mould, measurer, wear part at present.Do not find at present the bibliographical information that the Steel Bond Hard Alloy material is used as yet on the motor cylinder barrel.
Summary of the invention
The present invention solves available engine wear resistance problem, improves the whole service life of motor, provides cylinder barrel to be replaced motor---the motor that cylinder barrel is made by the Steel Bond Hard Alloy material with new material.
The present invention adopts following technological scheme to realize: a kind of motor, its cylinder barrel are that the Steel Bond Hard Alloy material of 30%-50% is made by the hard phase content.
In technical field of engines, the starting point that traditional concept for many years will improve and improve engine friction part wear resistance is placed on by certain technological means (as surfaces nitrided, plating, laser hardening etc.), in the improvement of the wear-resisting property of friction member material therefor (spheroidal graphite cast iron or aluminum alloy), improvement; And the present invention has overcome above-mentioned conventional art idea or perhaps technology prejudice just, do not start with from the wear-resisting property of improving spheroidal graphite cast iron, other wards off the small stream footpath, fully the cylinder barrel of motor is replaced with new material, though and Steel Bond Hard Alloy with the wear resistance of its high hardness and other premium properties at cutter, mould, obtained known application on the products such as measurer, but because cutter, mould, the technical field under the products such as measurer and the technical field span of motor are bigger, with the vulnerable part on the motor---cylinder barrel is replaced has unobviousness with Steel Bond Hard Alloy, and it is outstanding that key is that this replacement has brought, unforeseeable effect; And exploration uses new material to represent the trend of engine art development of new techniques on motor, present automobile manufacturing field, the new material of corresponding part on the motor car engine is just being studied and explored to particularly external big automaker, and the present invention replaces the trend that has adapted to this development of new techniques with new material to the cylinder barrel of motor.
The cylinder barrel of motor is replaced with Steel Bond Hard Alloy, motor can reduce does not even use overhaul, prolong engine life more than at least 5 years, therefore, can save great deal of raw materials, with 6.5 hundred million calculating of automobile pollution in the world, because of prolonging, engine life postpones the motor vehicle liquidation time limit, and the raw-material saving that is brought is inestimable especially; Improvement and maintenance motor are in good working order all the time, thereby save oil plant, reduce blowdown, improve environment protection effect.Application and the popularization of Steel Bond Hard Alloy on motor, its coverage is wide, industry is many, quantity is big, and extremely huge market is arranged; Though the present invention replaces the material of the cylinder barrel of motor, but undoubtedly, the present invention will be the last revolution of motor history, will produce hundreds of millions of economic benefits, all can exert an influence to the energy, the reasonable resources development and use in the China and the world.
Embodiment
A kind of motor, its cylinder barrel are that the Steel Bond Hard Alloy material of 30%-50% is made by the hard phase content.
Be with cylinder barrel in the cylinder body of motor, the present invention does not change structure, the structure of motor itself, just cylinder barrel is replaced with new material---the Steel Bond Hard Alloy material.
Steel Bond Hard Alloy usually with titanium carbide or Tungsten carbite as the hard phase.The used Steel Bond Hard Alloy material selection of cylinder barrel is the hard phase with the Tungsten carbite, and selects the GB F3001 and the F3002 trade mark for use, is characterized in and can heat-treats, and under annealed condition, machining such as can cut.Its hardness range is H
RC32-64 has higher wear resistance.
With the Steel Bond Hard Alloy of titanium carbide as the hard phase, except having high hardness identical and good wear resistance with Tungsten carbite hard phase alloy, the density of himself is less, weight is lighter, when needs alleviate the weight of certain motor, can preferentially select for use with the Steel Bond Hard Alloy of titanium carbide as the hard phase.
Claims (2)
1, a kind of motor is characterized by: its cylinder barrel is that the Steel Bond Hard Alloy material of 30%-50% is made by the hard phase content.
2, motor as claimed in claim 1 is characterized by: the used Steel Bond Hard Alloy material selection of its cylinder barrel as the hard phase, and is selected GB F3001, the F3002 trade mark for use with Tungsten carbite.
