Description
Technical field
Oozed with coating the present invention relates to a kind of aluminium alloy casting containing di-iron trioxide and prepare casting impregnation coating using it
Method, can effectively improve the decay resistance of Cast aluminium alloy gold surface, belong to casting technology field.
Background technology
Aluminium is a kind of active metal of chemical property, is just easy to be reacted with oxygen at normal temperatures, generates one layer of cause
Close and firm this layer film of aluminum oxide film can prevent the aluminium of internal layer from further aoxidizing, can meet it is used in everyday will
Ask.But under weak acid, alkalescence condition, the effect of this tunic is limited, it is impossible to the corrosion of aluminium alloy is effectively prevented, thus, to aluminium
The decay resistance of alloy proposes requirement higher.
Such as application of the cast aluminium in condensing type water heater.Condensing heat exchanger is set up in gas heater afterbody, it is possible to decrease row
Cigarette temperature, by the water vapor condensation in flue gas while obvious heat of smoke is discharged, is allowed to discharge latent heat of liquefaction, therefore its thermal efficiency
More conventional water heater is high by 10%~15%.Usual its exhaust gas temperature is less than 110 DEG C, and the thermal efficiency is not less than 96%.Using condensing
Another benefit of gas heater is that condensed water can be by SO in flue gasxAnd NOxDeng sour gas dissolving, flue gas can be effectively reduced
The pollution that discharge is caused, mitigates environmental pollution.
The heat conductivility of cast aluminium is excellent, and, apparently higher than cast iron, aluminium is cheap in addition for thermal conductivity, is adapted to industrial big rule
Mould is used.Secondly, from design, the Reliable Design of cast aluminium heat exchanger also makes it have sufficient advantage:Aluminium heat-exchange device
Wall thickness it is big, on the basis of heat transfer intensity higher is ensured, hydraulic pressure higher can be born, maintain operation steady in a long-term;And
There is good mobility, casting and excellent processability after aluminum alloy melting.Based on these features, cast aluminium condensing heat exchanger is near
It is developed rapidly over year.
But the acidic liquid that pH value is about 3~5 is formd because acidic materials are dissolved in condensed water, meeting heat exchanging device is cold
The aluminium alloy of solidifying section produces serious corrosion, reduces the service life of water heater, the security that influence is used.
Casting is oozed and is also Cast-in-place hardfacing, is that will can form the various alloy powders adhesion of surface particularity ergosphere, paste solid or apply
Brush in the particular surface of casting mold, then pour into a mould liquid metals, using its heat make coating material melt and with base metals thing
Reason is combined or reaction bonded, so as to form the technology of the coating with property in cast(ing) surface.With existing use anodic oxidation, electricity
Plating, chemical plating, laser melting coating, differential arc oxidation and plasma spraying etc., aluminium alloy surface treatment method are compared, and casting is oozed need not be special
The equipment of door, is not limited by cast shape, can process any surface of casting, and be combined for conventional cast and material surface by it
Reinforcement technique is combined, and is surface-treated while casting, and it is solidifying to take full advantage of the waste heat and molten metal of molten metal
Gu when latent heat, without following process, operation is simple, energy consumption reduction.
At present, the research of existing Infiltration technology also has Mg alloy castings technology of infiltration casting in recent years mainly around ferrous metal
Research, and there is presently no the research that Infiltration technology is applied to aluminium alloy.
