Thickness is thicker relative to the thickness of differential arc oxidation film layer 20 of the prior art, and the hole in film layer obtains in growth course
Effective closing, no penetrability micropore, Korrosionsmedium can not directly contact pot substrate layer 10, avoid pot substrate layer 10 by
To erosion, so as to protect film layer and base material to keep permanent service state.
Further, as illustrated in fig. 1 and 2, preferably above-mentioned differential arc oxidation film layer 20 also includes the second differential arc oxidation film layer 21,
Second differential arc oxidation film layer 21 is located between the differential arc oxidation film layer 22 of pot substrate layer 10 and first.Above-mentioned first micro-arc oxidation films
Layer 22 is more loose relative to the part differential arc oxidation film layer close to pot substrate layer, therefore referred to as weaker zone, the
Two differential arc oxidation film layers 21 are referred to as compacted zone, compacted zone and weaker zone interlocking shape, are not easy to separate.Compacted zone and pot base
Without big hole on interface between material layer, interface cohesion is good, and as shown in figs.3 a and 3b, Fig. 3 A show the tissue ratio of compacted zone
Relatively it is evenly distributed and completely, without defect, structure is suitable, Fig. 3 B is shown, fine and close compacted zone is actually very tiny lamella
What structure heap came, these lamella arrangements are quite compact, so that there is no open defect and space so that compacted zone hardness height,
Good mechanical property and good corrosion resistance；As illustrated in figures 4 a and 4b, Fig. 4 A show that the tissue of weaker zone is mixed and disorderly, and can clearly see
See a large amount of uneven distributions of lamellar structure, be uneven have many obvious holes and defect；What Fig. 4 B will be apparent that presents
One pattern for appearing in the hole on weaker zone, from the edge in hole it can be found that the lamellar structure of weaker zone is not so good as compacted zone
The arrangement of lamella result it is fine and close, firmly.It it is one general and when being taken a picture to weaker zone, the quantity of this hole is many
All over situation, this furtherly understands weaker zone leakiness, and then it is low relative to the hardness of compacted zone to result in weaker zone, machine
Tool poor performance, corrosion resistance are low.The thickness of above-mentioned compacted zone is more than the thickness of weaker zone, further effectively encloses hole, carries
The wearability of differential arc oxidation film layer 20 is risen.Because the particle diameter of lubricant particles is smaller, do not shown in above-mentioned each figure
Come.
In the application another kind preferred embodiment, above-mentioned differential arc oxidation film layer 20 also includes lubricant particles.It is logical
Cross and lubricant particles are set in differential arc oxidation film layer 20, differential arc oxidation film layer 20 is formed self-lubricating composite membrane layer, be based on
The presence of the lubricant particles, the film layer not only have good non-adhesion behavior, and will not be with the making property of abrasion of film layer
It can decline, there is good lasting non-stick on the contrary.
Above-mentioned lubricant particles use the less inorganic solid particles of surface roughness of the prior art, for example receive
Rice silica, TiO 2 sol, molybdenum disulfide and graphite particle, preferably above-mentioned lubricant particles are graphite particle, excellent
The particle diameter for selecting graphite particle is 0.5~0.9 μm.
In order to further improve the wearability of differential arc oxidation film layer 20, the hardness of preferably above-mentioned differential arc oxidation film layer 20 is more than

Present inventor has found when studying micro-arc oxidation process, the positive negative pulse stuffing dutycycle (duty of power supply
Than α=Tw/T, Tw represents positive negative pulse stuffing shared time within a pulse period, cycles of the T by pulse) can be micro- to what is formed
The pore size of arc oxidation film layer 20, porosity have an impact, for example when dutycycle is too low, oxide-film is loose porous；Dutycycle
When being increased to certain proportion, micropore size diminishes, porosity also diminishes；When dutycycle continues rise, now aperture becomes big, hole
Rate becomes big.It is preferred that in above-mentioned micro-arc oxidation process, the positive negative pulse stuffing dutycycle for controlling power supply is 10~50%.To control differential of the arc oxygen
The pore size and porosity for changing film layer 20 form suitable matching.
Above-mentioned preparation method by adding lubricant particles in the electrolytic solution simultaneously, so as to form the differential of the arc in differential arc oxidation
During oxidation film layer 20, lubricant particles also are deposited upon in differential arc oxidation film layer 20 therewith, obtain with solid
The differential arc oxidation film layer 20 of lubricated granules, and while lubricant particles deposit, formed micro-arc oxidation films can be influenceed
The pore size of layer and the pore size and hole of porosity, especially the part differential arc oxidation film layer away from pot substrate layer
Rate, so as to obtain porosity as 5~30%, first differential arc oxidation film layer 22 of the aperture between 3~10 μm.
Due to containing lubricant particles in differential arc oxidation film layer 20, differential arc oxidation film layer 20 is set to form self-lubricating composite membrane
Layer, the presence based on the lubricant particles, the film layer not only have good non-adhesion behavior, and will not be with the mill of film layer
Damage makes hydraulic performance decline, has good lasting non-stick on the contrary.Simultaneously as differential arc oxidation film layer 20 is in base material growth in situ
Film layer, the combination of film layer and pot substrate layer 10 belongs to metallurgical binding, and bond strength is high, will not be drawn in cooking process because of external force
Wipe and damage and come off, also because of expanding with heat and contract with cold film layer will not be caused to come off.
Further, the frequency of power supply can also form certain influence to the thickness of differential arc oxidation film layer 20 and aperture, excellent
Choose and state in micro-arc oxidation process, the frequency for controlling power supply is 200~800Hz.The frequency both can guarantee that micro-arc oxidation process not
The phenomenon of workpiece ablation occurs, and can guarantee that differential arc oxidation film layer 20 thickness and aperture in the preferred range.
As mentioned by background technology, the hardness of resulting differential arc oxidation film layer 20 has deficiency at present, in order to enter one
Step improves the thickness of differential arc oxidation film layer 20, preferably in micro-arc oxidation process, control the direct impulse of power supply for 300~
700V, negative-going pulse are 80~100V.The control of above-mentioned direct impulse and negative-going pulse is advantageous to improve differential arc oxidation film layer 20
Hardness, can be by micro-arc oxidation films when above-mentioned direct impulse, negative-going pulse and foregoing dutycycle, frequency are coordinated
The hardness of layer 20 is improved to more than 1600HV.
Further, in order to improve differential arc oxidation efficiency, preferably in above-mentioned micro-arc oxidation process, the electric current of power supply is controlled
Density is 3~4A/dm 2。

Electrolyte include 2g/L~20g/L sodium metasilicate, 0.5g/L~2g/L potassium hydroxide and 2g/L~8g/L sodium tungstates.Wherein,
Sodium metasilicate is used to reduce arcing voltage, and potassium hydroxide is used to control electrolyte for alkalescence, and sodium metasilicate and potassium hydroxide not only may be used
To provide more adions, and the electrical conductivity of electrolyte will also improve, therefore the reduction that will cause critical discharge voltage,
Improve film forming speed.The use of sodium tungstate is mainly to adjust the color of formed micro-arc oxidation films, can make oxide-film surface
Produce obvious melanism；In addition, the concentration of sodium tungstate also influences the thickness of differential arc oxidation film layer to a certain extent, such as
Increase concentration of sodium tungstate, oxide thickness, which increases and thickens speed, to accelerate, but its influence to thickness is relative to differential of the arc oxygen
It is small to change the thickness of of film layer itself, can be ignored.
