In order to which technical solution of the present invention and advantage is more clearly understood, below in conjunction with drawings and the embodiments, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are only used to illustrative illustrate originally
Invention, is not intended to limit the scope of protection of the present invention.
In embodiments of the present invention, a kind of processing method of metal blade is proposed.Fig. 2 is metal leaf of the present invention
A kind of implementation flow chart of the processing method of piece, referring to fig. 2, a kind of embodiment of the processing method of the metal blade are mainly wrapped
It includes:
201, differential arc oxidation is carried out to metal blade.
202, solid lubricant is applied to the metal blade, wherein the micropore of the differential arc oxidation layer on the metal blade
Supporting body as the solid lubricant.
By processing of the invention, the metal blade has following feature: the metal blade has differential arc oxidation
Layer；The differential arc oxidation layer has solid lubricant, wherein the micropore of the differential arc oxidation layer is as the solid lubricant
Supporting body.
The differential arc oxidation (MAO) is a kind of plasma electrolysis deposition technology, is by electrolyte and corresponding electrical parameter
Combination, aluminium, magnesium, titanium and its alloy surface by arc discharge generate TRANSIENT HIGH TEMPERATURE high pressure effect, grow with matrix
Ceramic film based on metal oxide.Differential arc oxidization technique breaches the voltage limitation of traditional anodic oxidation, can be quick
Generate thicker oxide layer.
Fig. 3 is the schematic diagram of differential arc oxidation production equipment.Referring to Fig. 3, the production process of differential arc oxidation is relatively easy, will not
It is related to costly and complicated equipment, compared with prior art CuNiIn material layer, the present invention can be prepared with simple equipment, production
Cost is cheaper.The equipment being directed to include multifunctional power 301, stainless steel sink 302, blender 303, thermometer 304,
Cooling system 305, has electrolyte in the stainless steel sink 302, and metal blade 306 is placed in the electrolytic solution, by multi-functional electricity
The power supply of source 301 carries out differential arc oxidation to the metal blade 306.
The thickness for the oxide layer that the differential arc oxidation generates can by time of differential arc oxidation, electrolyte concentration, with
And the mode for applying voltage (up to 2kV) to selected electrolyte is adjusted, and in the preferred embodiment, the gold
The preferred thickness for belonging to the differential arc oxidation layer of blade can be 100 to 500 microns.
The hardness for the oxide layer that the differential arc oxidation generates can be by the concentration of electrolyte and to selected electrolyte
It applies alive mode to be adjusted, the hardness of the differential arc oxidation layer can be up to 1000-4000 Vickers hardness (Hv).
Since the differential arc oxidation layer of the metal blade has preferable thickness and hardness, have outstanding wear-resisting
Property, especially have outstanding fretting wear resistance property.
Moreover, differential arc oxidation layer is since the differential of the arc dissolves, meeting and metal blade unlike other existing thermal Sperayed Ceramic Coatings
Surface carry out metallurgical bonding, to have very high adhesion strength, not cracky.If Fig. 4 is traditional anodic oxidation and the differential of the arc
Aoxidize the surface of the oxide layer generated and the contrast schematic diagram of cross section.Left side 401 generates in Fig. 4 for traditional anodic oxidation
Oxide layer, top half 411 are the surface of the oxide layer, and lower half portion 412 is the cross section of the oxide layer.Right side 402 in Fig. 4
For differential arc oxidation differential arc oxidation layer generated, top half 421 is the surface of the differential arc oxidation layer, and lower half portion 422 is should
The cross section of differential arc oxidation layer.Compare traditional anodic oxidation and oxide layer cross section that differential arc oxidation generates this it appears that
The oxide layer of differential arc oxidation is even closer in conjunction with parent metal.
In addition, differential arc oxidation layer also shows less defect and good toughness.The toughness refers to: can be according to need
The power of adjustment differential arc oxidation and the ingredient of electrolyte are asked, so that differential arc oxidation layer generates in corresponding structure
Change, to be suitable for different scene demands.By taking aluminium alloy as an example, different from the amorphous structure that anodic oxidation is formed, the differential of the arc
Oxidation is formed by ceramic structure mainly by γ-Al2O3Phase and α-Al2O3Phase composition, wherein α-Al2O3Mutually make film hardness it is high,
Wearability is good, and γ-Al2O3The toughness for mutually having had film layer can accordingly adjust two-phase by adjusting differential arc oxidation parameter
Ratio, to optimize the comprehensive performance of oxidation film.These features of differential arc oxidation make differential arc oxidation layer be suitable for metal leaf
The protection of piece fretting wear.
Meanwhile electrolyte used in the differential arc oxidation is neutral or weakly alkaline solution, wherein heavy metal is not added, because
This pollution on the environment is small, and opposite conventional anodization or chromaking surface treatment are environmental-friendly.And differential arc oxidation is forever
For night temperature based on room temperature, variation range is wider, easily operated.In addition, because not being related to the high-temperature heat treatment to parent metal
Process, thus will not shape to blade and mechanical performance adversely affect.
One feature of differential arc oxidation layer be oxide layer it is thicker and have porosity, it is from Fig. 4 it will be clear that micro-
There are many micropores on the surface of arc oxide layer 421, these micropores may be certain defect of differential arc oxidation layer, example in some aspects
As these micropores may influence whether the corrosion resistance of differential arc oxidation layer.However, differential arc oxidation is but dexterously utilized in the present invention
These micropores on layer.I.e. the present invention applies solid lubricant to the metal blade, wherein the differential of the arc on the metal blade
Supporting body of the micropore of oxide layer as the solid lubricant.That is, the protection of the fretting wear for metal blade
