2, partition carries out phosphorating treatment, and the phosphatization effect of silicon aluminum alloy material is good, and the phosphating coat wearability that baffle surface is formed is more
It is excellent, meet the requirement under compressor limiting condition to partition wearability, and the process costs of partition are lower.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is the schematic diagram of internal structure of compressor in the preferred embodiment of the present invention.
Specific embodiment
The present invention proposes that partition uses alusil alloy material, and the surface of partition is coated with phosphating coat after phosphorating treatment.Every
The alusil alloy material of plate contains 17-32%Si, 5-10%Cu, 2-5%Zn, 0.6-2%Mn, 1-2%Mg, 0.7-1.5%Fe, 0.1%RE,
Remainder is Al.The alusil alloy material composition of partition has prevented adding for heavy metal antimony compared with general al alloy component
Add, although the hardness and strength of alloy can be improved in heavy metal element, the element is toxic and price is higher, removes removing heavy metals
On the one hand element can reduce cost, on the other hand can reduce the harm to environment and human body, keep material more environmentally-friendly.It is more excellent
, the content of Zn and Mg are improved in the alusil alloy material of partition, effectively facilitate MgZn2 binary hardening constituent in alloying component
It generates, MgZn2 content increases the intensity and hardness that partition can be improved.
More preferably, be also added into micro rare earth element in the alusil alloy material of partition, the addition of rare earth element so that
Alloy flowability is improved, and the effect for refining phosphatization crystal grain is more preferable, the phosphating coat fine microstructures that partition phosphorating treatment obtains, phosphorus
There are certain holes in change membrane tissue, can be reduced between partition and piston with oil storage in gap when compressor is run
Frictional dissipation.Meanwhile using partition quality made of alusil alloy material being only the 1/3 of castiron partition quality, it can be with
Effectively mitigate compressor weight, avoids moving component is overweight from causing that vibration of compressor is big, balance is poor.
Specifically, the parkerizing method of partition includes: that the partition of alusil alloy material is immersed in phosphating solution, every
The surface of plate forms the phosphating coat of the grains formed with calcium phosphate precipitation object.Phosphating solution is by phosphoric acid, dihydric phosphate, promotor
Or the composition such as oxidant, water, dihydric phosphate is containing Zn, Mn, Fe, Ni, Ca etc..The total acidity 30-40 point of phosphating solution, free acidity
5-10 point, the temperature of phosphating solution is at 90 degree or more.
The forming process of phosphating coat is as follows:
1, the multiple ionization of phosphoric acid
H3PO4→ H2PO4 -+ H+→ HPO4+2H+ →PO4 3-+3H+
Firstly, the etch of phosphoric acid makes the reduction of baffle surface H+ concentration, due to the H of baffle surface+Concentration sharply declines, and leads to phosphoric acid
Root ionization at different levels carry out to the right, and final ionization is PO4 3-。
2, calcium phosphate precipitation
As the PO that baffle surface dissociates4 3-With (metal interface) metal ion in solution: being mainly Zn2+、Mn2+、Fe 2+It reaches
When to solubility product constant Ksp, calcium phosphate precipitation will be formed in metal surface.
3Zn2++2PO4 3-+4H2O→Zn3(PO4)2.4H2O
Zn2++Fe2++PO4 3-+H2O→Zn2Fe(PO4)2.4H2O
Or 3Mn2++2PO4 3-+4H2O→Mn3(PO4)2.4H2O
Mn2++Fe2++PO4 3-+H2O→Mn2Fe(PO4)2.4H2O
Calcium phosphate precipitation and hydrone are formed together phosphatization nucleus, and nucleus continues to grow up into phosphatization crystal grain, numerous crystal grain
Combining closely finally can just integrate phosphating coat.The content that Mn, Zn element are improved in the alusil alloy material of partition, on the one hand makes
Alloy strength, hardness raising are obtained, the Zn being precipitated in alloy is on the other hand improved2+、Mn2+Concentration, so that phosphatic forming amount
It is more much higher than conventional aluminum alloys, eventually lead to better effect of the phosphorization film quality compared with conventional aluminum alloys, quality of forming film and resistance to
Mill property is also 2 times of Conventional alloys or so.
In order to optimize parkerized effect, before partition is immersed in phosphating solution, first the surface of partition is carried out pre-
Processing, pretreatment include oil removing, derusting and the neutralization successively carried out, and oil removing, derusting and neutralization technique are existing mature technologies,
Its process is well known to those of ordinary skill in the industry, therefore not to repeat here.Compared with the pretreatment before traditional phosphating solutions processing, this hair
Table tune technique is eliminated in bright middle preprocessing process, table tune technique is chiefly to facilitate the phosphatization that phosphatization forms the careful densification of crystal grain
Film, this is because there is the addition phosphatization crystal grain of rare earth element to be refined, in matching for phosphatization liquid acidity and phosphatization temperature
Under conjunction, gained phosphorization membrane is thin and careful, therefore does not need table tune technique and optimize processing to baffle surface.Of the invention is pre-
Processing and phosphorating treatment whole process only need 20min or so, general 1-2 μm of the phosphating coat obtained after phosphatization, do not change substantially
The size and surface roughness of alusil alloy partition, technical process are simple, at low cost.
As shown in Figure 1, in a preferred embodiment, the present invention also proposes that the compressor with aforementioned barriers, compressor also wrap
Include: upper cylinder 1, lower cylinder 2 and crankshaft 3, partition 4 are arranged between upper cylinder 1 and lower cylinder 2, and the center of partition 4, which is equipped with, to be used for
The through-hole that crankshaft passes through is additionally provided with suction hole 5 on partition 4, and upper cylinder 1 is equipped with inlet channel 6, and suction hole 5 is connected to inlet channel 6
With the inner cavity of lower cylinder 2, suction hole 5 is obliquely installed, and the angle between 6 axis of 5 axis of suction hole and inlet channel is less than 90 degree.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
