Description
Technical field
It is modified and uses the present invention relates to a kind of glass dust and its preparation technology, more particularly to a kind of plasma spraying ceramic coat
Glass dust and its preparation technology.
Background technology
With continuing to develop for modern science and technology, each industrial department especially department such as metallurgy, chemical industry, aerospace, energy makes
More and more harsher with the corrosive environment of operating mode, etching problem is increasingly severe.In some cases, ordinary metallic material is even
When specialty alloy materials are all difficult to meet the requirement of its corrosion resistance, ceramic coating just shows its distinctive corrosion resistance, obtains more next
More it is widely applied.Most of ceramic materials are shown very strong due to its stable crystal structure and stronger chemical bond force
Chemical inertness, because free electron shifts gain and loss and is easily corroded unlike metal material.In natural environment, including it is big
In the environment such as gas and water, ceramic material corrosion rate very little is made pottery usually through the mode of plasma spraying in metal base surface
Porcelain coating is used for corrosion-resistant field.Plasma spraying is, using plasma arc as thermal source, to make height by high temperature, high speed, high enthalpy flame stream
Melting material melts and obtained the spraying method of high-quality composite coating, especially fits and prepares ceramic coating.Due to ceramic coating tool
There are high rigidity, highly corrosion resistant, surfacecti proteon that is wear-resisting and being widely used in machinery.In a variety of ceramic coatings, Al2O3-
13wt.%TiO2(AT13)Nearly hundred kinds zero in relevant devices such as Aero-Space, military project, water conservancies of compound oxidate ceramic coating
It is applied widely on part.But because plasma spray coating process determines the layer structure of gained coating, in spraying process
The defects such as hole, micro-crack are inevitably produced, the corrosive medium that exists for of these defects is penetrated into there is provided passage.In corruption
Lose under environment, corrosive medium reaches the interface of coating/metal by the defect of ceramic layer, and serious electrification occurs in metal surface
Corrosion, corrosive liquid are learned once penetrating into, corrosion reaction is quickly grown, corrosion product expands, in addition ceramic coating internal residual stress
Effect causes micro-crack extension, causes coating cracking and peeling, greatly reduces service life of the coating in corrosive environment, limits
Application of the plasma spraying ceramic coat in corrosion-resistant industry is made.The presence of the faults of construction such as coating mesopore, crackle, not only
The decay resistance of coating is reduced, and reduces the mechanical performance of coating, the heterogeneous microstructure of coating is have impact on and shows
Microhardness, easily causes the generation of micro-crack in coating, or even influence the binding ability of coating.As can be seen here, coating is improved fine and close
Degree, it is to improve one of key element of coating service life to make porosity reduction or dead-end pore.
For many years, many scholars are studied in terms of improving coating consistency, improving ceramic coating corrosion resistance, mainly
Process modification and post processing can be divided into, by Optimizing Process Parameters improve coating consistency, reduce porosity, but due to etc. from
The characteristics of sub- spraying coating process itself, determines the presence of defect, and the degree that consistency is improved by the method for process modification is limited
's.Also relatively more, such as sealing pores of the technique study of post processing, i.e., enter to the hole, through hole and micro-crack of coating surface
Row closing, to improve corrosion-resistant, the abrasion resistance properties of coating.In recent years, a variety of method for sealing are developed both at home and abroad, such as using envelope
Hole agent directly carries out sealing pores, carries out sealing pores using methods such as sol-gel, heating diffusion-laser irradiations, utilizes powder
The property of powder material in itself carries out the method such as sealing pores and plating sealing of hole.
Sol-gel sealing of hole can make the increase of coating consistency, and improve bond strength, but the control of temperature is by strict
Limitation, it is difficult to obtain satisfied effect, gelation is insufficient when temperature is low makes sealing pores not exclusively, and temperature is more than 300 DEG C,
Firm nature of glass sealing of hole layer is formed because hole sealing processing agent itself is inorganization, while occurring significantly to shrink, makes sealing
Layer is cracked again, and decay resistance is degrading on the contrary.Irradiated using laser and carry out the top layer that sealing pores can obtain densification,
But laser technical parameterses are difficult to control, and power is too big may to cause the problems such as ceramic coating is cracked, peeled off.Asked for this
Inscribe, Liscano etc. is infiltrated to ceramic coating in advance using organic sealing agent, then with laser remolten, obtained preferably
Effect.But laser remolten cost is higher, and secondary stress easily is produced in coat inside, reduce the binding ability of coating.
It is also processing method common at present to carry out sealing pores using the property of dusty material in itself, and some make use of certain
A little metal-ceramic composite powders have good self sealing action, make the micropore voluntarily soldering in coating, form dense non-porous
The patent of coating, such as Patent No. 201510591945.X.The direct method of pore sealing of hole sealing agent is easily realized and obtained due to simple to operate
Wide application, but the anticorrosion effect of this method is limited by the property of hole sealing agent, it is impossible to tackle the problem at its root
And realize long-effective corrosion.
Either to heating after the coating progress of preparation so that coat inside micro-crack makes up and improves coating densification
Degree, or sealing pores are carried out by organic resin, the actual demand that effect is good and cost is low can not be met, heating effect is not
Significantly, and organic resin can improve the corrosion resistance of coating, but virtually improve cost, the mode of post processing can only take stopgap measures
It can not effect a permanent cure.Accordingly, it is considered to from source, improve the property of dusty spray, so as to improve the quality of coating.With plasma spray
Apply conventional Al2O3-13wt.%TiO2Exemplified by, the pattern particle of the powder is in polygon, rather than circular, this just determine through
Cross the molten drop that the heating of plasma flame flow high speed high enthalpy obtains and can not sprawl into plain film dress, i.e. molten drop completely and sprawl what is obtained after shaping
There are a large amount of holes in coating.
Glass dust is amorphous amorphous substance, and without definite melting point, but softening temperature is relatively low.As temperature is raised, glass
The viscosity of glass melt can be significantly reduced, the low viscosity melt as the preferable similar liquids of mobility.If glass dust adulterated
In spraying ceramic powders, the fluidity that melted powder is sprawled certainly will be increased, play a part of high-temperature inorganic adhesive, and fill out
The hole between ceramic particle is mended, porosity is fundamentally reduced, fine and close coating is formed.And can glass dust be substantially filled to
Hole is simultaneously bonded with ceramic material, and its key is glass dust mobility in the molten state and glass dust and ceramic material
Sb is introduced in Wet Out, formula2O3The transition temperature of glass can be reduced, the mobility of glass is improved, the chemistry of glass is improved
Stability.In addition, Sb2O3And Cr2O3The surface tension of glass, wherein Cr can be reduced2O3Effect is the most notable, surface tension
Reduction can reduce the angle of wetting of glass and ceramic material, so as to improve its wetting effect so that glass melts are sufficient filling with
Into ceramic hole.
Silicate glass is one of conventional glass system, with higher chemical stability, forming area of glass scope compared with
Width, easily forms amorphous glass, and cost is low.Therefore, silicate glass powder of the exploitation with compared with high chemical stability, with suitable
Suitable ratio is doped in ceramic powders, prepares fine and close, excellent anti-corrosion performance glass dust doping AT13 ceramic coatings, has
Hope the long-effective corrosion for realizing ceramic coating.
The present inventor practical experience and professional knowledge abundant for many years based on such product design manufacture is engaged in, and coordinate
The utilization of reason, is actively subject to research and innovation, and a kind of the glass of plasma spraying ceramic coat corrosion resistance can be improved to found
