Abstract
The invention mainly relates to sealing material fields, disclose a kind of durable use for diesel engine sealing element, consist of the following components in percentage by weight：Copper 2 ~ 3%, manganese 2 ~ 3%, silica 1 ~ 2%, white carbon 1 ~ 1.5%, nickel 0.5 ~ 1.6%, vanadium 1 ~ 2.6%, boron 1.3 ~ 3.5%, remaining be aluminium and inevitable impurity；Various metals and nonmetallic raw material is added, hence it is evident that improve the corrosion resistance of sealing element, service life extends；After aluminium is melted completely, nonmetallic raw material heat preservation is added and dissolves, so that raw metal and nonmetallic raw material is sufficiently mixed, improves the antirust ability and wear-resisting property of sealing element；Fully cool down stage by stage after melting, reduces the crystal grain of crystallization, improve the intensity, hardness and toughness of sealing element, enhance the corrosion resistance of sealing element.
Description
Technical field
The invention mainly relates to sealing material field more particularly to a kind of durable use for diesel engine sealing elements.
Background technology
Diesel engine can use diesel oil, lubricating oil, generate higher temperature in the process of running, diesel engine sealing performance it is good
It is badly directly related to the operation of automobile, the sealing element corrosion resistance on diesel engines at present is weaker, easy tos produce abrasion and corrosion, makes
The spoilage of diesel engine is higher, and the maintenance cost of diesel engine is higher, hence it is evident that improves the use cost of diesel engine.
Invention content
In order to make up the defect of prior art, the object of the present invention is to provide a kind of durable use for diesel engine sealing elements.
A kind of durable use for diesel engine sealing element, consists of the following components in percentage by weight：Copper 2 ~ 3%, manganese 2 ~ 3%, two
Silica 1 ~ 2%, white carbon 1 ~ 1.5%, nickel 0.5 ~ 1.6%, vanadium 1 ~ 2.6%, boron 1.3 ~ 3.5%, remaining for aluminium and inevitably it is miscellaneous
Matter；The silica, grain size are 20 ~ 50nm.
Include the following steps：
（1）Aluminium is heated to 1800 DEG C, impurity is removed, obtains molten aluminum liquid.
（2）Silica, white carbon and boron are added in molten aluminum liquid, obtain mixture, then cooling cooling thing, then
To secondary mixture, after cooling, by mixture note in mold, 60 ~ 260 DEG C is naturally cooling to, stripping forming is carried out, must seal
Part blank.
（3）Sealing element blank is added in heating furnace, carbon dioxide gas is passed through, is warming up to 1.8 DEG C/min of speed
It 800 DEG C, is quenched in urea liquid after taking-up, obtains the corrosion-resistant sealing element for diesel engine；Sealing, packaging, must be used for
The corrosion-resistant sealing element finished product of diesel engine.
It is an advantage of the invention that：Provided by the present invention for the corrosion-resistant sealing element of diesel engine, various metals and non-are added
Raw metal, hence it is evident that the corrosion resistance for improving sealing element after melting aluminium completely, is added nonmetallic raw material heat preservation and dissolves, make gold
Belong to raw material and nonmetallic raw material is sufficiently mixed, improves the antirust ability and wear-resisting property of sealing element；Fully melting after stage by stage into
Row cooling, reduces the crystal grain of crystallization, improves the intensity, hardness and toughness of sealing element, enhance the corrosion resistance of sealing element；It is added surplus
Under raw material after be rapidly heated, make the abundant melting mixing of raw material, slowly rise again again after Temperature fall crystallization, it is accurate to improve raw material
Degree, enhances the corrosion resistance of sealing element；It is passed through carbon dioxide gas after sealing element stripping forming to be heated, carbon atom is made to penetrate into
Sealing element, heating, which is placed in urea liquid, to be quenched, and is formed protective film in seal surface, is improved the stability of sealing element
And corrosion resistance.
