Description
Technical field
The invention belongs to renovation agent field, metallic surface, specifically, relate to a kind of abrasion-resistant metal, drag reduction and the face of damage renovation agent and preparation method thereof.
Background technology
Frictional wear is the mechanical means phenomenon that certainly exists in service.There is 1/3rd energy be used to overcome friction resistance mechanical means in service.Be the main link of energy consumption, wearing and tearing are signs of mechanical movement length equipment life, when abrasion loss exceeds the equipment design requirement, indicate the termination of this equipment life.Pertinent data shows that the U.S. is annual above 200,000,000,000 dollars because of the financial loss that frictional wear causes.Along with Chinese economic development, become a mechanical means equipment big country, the mechanical means production also will become mechanical means in the near future and make big country also in fast development.Only mechanical friction is worn and torn the annual financial loss that causes to China up to exceeding 100 billion at present.The problem that present China mechanical means mainly exists has:
(1) there is gap in manufacturing accuracy
World's lathe precision is generally higher at present; Developed country such as Europe particularly; The positioned centrally precision generally surpasses ± 5 μ m; Countries such as moral, U.S.A, day, Switzerland even reached ± 3 μ m, ± 2 μ m, ± 1 μ m, and the like product bearing accuracy of China exists very big gap compared with developed countries more than ± 8 μ m.
The main problem that exists in manufacturing processed: the one, the machine-tool of self is long most duration of service; The precision forfeiture greatly; Produced element precision is affected, and component tolerances is big, causes China's mechanical means just to exist precision low from the beginning of dispatching from the factory; Work-ing life is short, consumes big defective.The 2nd, along with the prolongation of duration of service, the wearing and tearing of running position, corrosion, a large amount of fund of annual maintenance cost is used for purchase of equipment, and equipment can not influence the quality of product with same precision work in maintenance cycle.The 3rd, because there is gap in the manufacturing general assembly level of mechanical means, cause the mechanical means precision to be difficult to reach higher level, the equipment operation noise is bigger.
(2) precision stability is poor
Mechanized equipment, processing units that country such as moral, U.S.A, day, Switzerland makes can keep service precision for many years; And the product of China generally can only keep about in the of 1 year; Its major cause; The one, problem of materials, China's metallurgical industry also has big gap with comparing abroad, and the congenital defect of material is that the precision stability difference gets major cause; The 2nd, the mechanical means plant precision of machine-tool own is not high, and the part that processes much is to be in limit tolerance, and it is insuperior to add assembly technology and technology, and this is another major reason of domestic machinery equipment precision stability difference; The 3rd, thermal treatment process and equipment also have certain gap compared with developed countries; The 4th, domesticly ignored the control of process optimization and precision in the machinofacture roughing stage, precision work is of low quality, makes the machinery back precision stability that comes into operation poor.
(3) maintenance cost is high
The wear out failure of mechanical means often is that the wearing and tearing of lacking part key component friction surface cause.Such as the guide rail of lathe, main journal etc., and this surface abrasion has only tens microns usually.The main maintenance mode of mechanical means is an abrasion piece of changing these positions at present.China reaches hundreds billion of dollars more than from the electronic product of external import at present, the annual outer component of buying these expensive rapid wears of remitting that need labor.Many enterprises generally will exist the repairing phase that equipment has arrived regulation; Make equipment in " morbid state ", adhere to work because of bearing enormous expenditure, influenced quality product, also make equipment aggravation wearing and tearing; Even cause the badly damaged generation with accident of equipment, thereby cause bigger loss.Even mechanical means is through after keeping in repair simultaneously, maintenance does not reach the standard when dispatching from the factory, especially precision, noise aspect.The oil seepage phenomena of equipment is ubiquity especially.
(4) because the component working accuracy is low, and the ME difference causes the equipment frictional coefficient higher, equipment operation process autophage power is big.
