Method.
Background technology
As one of the core component of internal combustion engine, its inwall is directly contacted cylinder jacket with high temperature, high-pressure gas, operating temperature
Height, thermic load is big；And the reciprocal relative movement of high speed is done with piston, cylinder inner wall not only will bear strong friction and wear,
Still suffer from the side-thrust of the impact of piston, thus producing very big thermal stress and mechanical stress in cylinder internal；Cylinder jacket
Residing working environment is extremely severe.The quality of its quality directly affects usability, reliability, economy and the longevity of internal combustion engine
Life.
Content of the invention
It is an object of the invention to provide a kind of aluminum alloy cylinder sleeve and its production method, make that cylinder jacket is wear-resisting, anti-attrition, resistance to height
Temperature, thus improving engine power, reducing oil consumption, reducing exhaust emission.
For achieving the above object, the present invention adopts following technical proposals：
A kind of aluminum alloy cylinder sleeve, contains the enhancement layer of AlSiTi and Si particle by outer layer, in radial directions without particle
Middle base layer and the composition of three layers of the internal layer containing primary crystal Si particle, tied by way of metallurgical between described three layers
Close.
The method manufacturing described aluminum alloy cylinder sleeve, comprises the following steps：
Step one：Al selected by cylinder sleeve matrix material, and adds Si and Ti to form Al-Si-Ti alloy in liquid Al alloy,
Wherein, Si content is 15-24wt.%, and Ti content is 6-12wt.%, and a small amount of Cu, Mg, Ni, and remaining is Al；
Step 2：Cylinder jacket is placed on and oozes in pottery stove, energising preheating 2.5 hours, temperature is risen to 255 DEG C ± 5 DEG C -265 DEG C
±5℃；
Step 3：Vacuumize, open vavuum pump, make to ooze the vacuum control made pottery in stove in the range of 45Pa-48Pa；
Step 4, it is passed through nitrogen, silane, borine, be passed through and oozed by the borine of the nitrogen of 75-77%, the silane of 12-14%, 11-13%
In pottery stove, and control flow, keep oozing the vacuum in pottery stove；
Pottery is oozed in step 5, insulation, cylinder jacket is oozed the Control for Kiln Temperature of pottery stove in the range of 265 DEG C ± 5 DEG C, insulation goes out for 8 hours
Stove；
Step 6：Cooling is come out of the stove.
The present invention compared with prior art, has the advantages that：
The cylinder jacket of the present invention, has lightweight, particle volume percentage composition height, good mechanical performance and resistance to elevated temperatures, energy
The advantages of operating efficiency of raising engine, and obtain one layer of ceramic membrane in interior surface of cylinder liner, both increased cylinder jacket
High temperature hardness, make inner surface of cylinder liner have a self lubricity again, reduce friction, metal and ceramic element directional diffusion, composite membrane
Sound construction will not fall off.
Specific embodiment
With reference to specific embodiment, the present invention is done and supplement further, but limit the present invention never in any form.
A kind of aluminum alloy cylinder sleeve, the enhancement layer containing AlSiTi and Si particle by outer layer in radial directions, does not contain
The middle base layer of particle and three layers of composition of the internal layer containing primary crystal Si particle, pass through metallurgical side between described three layers
Formula combines.
The method manufacturing described aluminum alloy cylinder sleeve, comprises the following steps：
