Anticorrosion effect is carried out with high temperature resistant molten aluminum etching ground of the invention and conventional " zinc oxide+waterglass " coating
Comparative test, specific test method are as follows:
No. 1 sample brushing " zinc oxide+waterglass " coating, then 300 DEG C or so drying, then brush again one layer " zinc oxide+
Waterglass " coating, is dried again, drying is brushed repeatedly, until coating layer thickness reaches 0.2~0.3mm；
No. 2 sample brushings high temperature resistant molten aluminum etching ground embodiment 4 of the invention, coating layer thickness are 0.3~0.4mm, to
After the coating on surface spontaneously dries, No. 3 samples are put into resistance furnace in 950 DEG C of progress high temperature sinterings, and keep the temperature 30min, with furnace
It is cooling.
The specific method of molten aluminum immersion corrosion test is to be immersed in 1, No. 2 sample in molten aluminum liquid slowly, soaking temperature is
750 DEG C, soaking time is 72 hours.
After experiment, sample is taken out from molten aluminum, observes its macro morphology and take pictures.Then abate or scraper surface
The aluminium sticked weighs after cleaning out and records the weight after three pieces of samples are corroded by molten aluminum.
Sample is carried out intercept → inlaying → respectively and polish → polishing → and corrode, corrosive agent is nital.In light
Learn its metallographic microstructure of microscopically observation.
Fig. 1 .a, b, c are blank sample primary morphology, before exfoliation surface aluminium layer and peel off the pattern comparison diagram after aluminium layer.Figure
1.b shows blank and produces serious buckling deformation after corroding；(Fig. 1 .c), the matrix of exposing after the aluminium layer on flake-off surface
Surface irregularity has very more silver-gray intermetallic compounds to be mixed in matrix surface, and the thickness of sample is than original
It is thinned half, it is possible thereby to infer, molten aluminum is chemically reacted with iron matrix, is generated intermetallic compound, is made steel-based
Body receives serious corrosion.Therefore, in the case where no any coating is protected, molten aluminum is very tight to the corrosion of steel material
Weight.
Fig. 4 is the matrix boundary metallographic structure of blank sample, from the figure, it can be seen that after molten aluminum 72 hours impregnate
Q235 steel substrate tissue is divided into three layers.A layer tissue is silvery white in color in figure, is after the tissue directly contacted with molten aluminum, aluminium is former
The iron aluminum metal compound layer that son is penetrated into and generated with iron-based precursor reactant, compound layer shows dendroid as we can see from the figure
Pattern, and to penetrating into inside matrix, and the organized layer is mingled with a large amount of hole.And c layer tissue is
Former base body tissue.There is one layer of corrosion transition zone b in the intersection of iron aluminum metal compound a layer and c layers of steel substrate tissue.Metallographic
Blank sample is also shown by molten aluminum heavy corrosion in organization chart, and changes the institutional framework and ingredient of protocorm.
Fig. 2 a, b, c are No. 1 sample primary morphology, before exfoliation surface aluminium layer and peel off the pattern comparison diagram after aluminium layer, are not had
Occur molten aluminum corrosion phenomenon, also there is no thermal deformations, but the position that sample is not soaked into molten aluminum is heaved, coating with
Matrix is detached from, and makes steel substrate exposure in air.When peeling off the aluminium layer that specimen surface sticks, Zinc oxide coating also follows one
It rises and falls off, Fig. 2 .c is the sample pattern after flake-off aluminium layer, and there is no variations substantially for outer dimension, however surface is but
There is the trace being oxidized, the part in figure being in black is exactly the matrix surface being oxidized.Traditional " zinc oxide+waterglass " is protected
Although shield coating can obstruct contact of the molten aluminum liquid with steel substrate well, the coating is not fine and close enough, can not obstruct
Oxidation corrosion of the pyro-oxidation-reduction gas to steel substrate above aluminum melt.Further, since not shape between coating and matrix
At metallurgical bonding, only exist mechanical interlock and suction-operated, thus coating in conjunction with matrix loosely, only used and once just lose
Protective effect, service life are very short.
Fig. 5 is the matrix metallographic structure figure after No. 1 sample corrosion, it can be seen that in the boundary of steel substrate, is occurred
One layer and the different separate layer of matrix.
Fig. 3 a, b, c are No. 2 sample primary morphologies, before exfoliation surface aluminium layer and peel off the pattern comparison diagram after aluminium layer, outside
Shape size does not free variation, and the aluminium layer of surface adhesion can gently be peelled off with hand, can see intact guarantor at this time
Protect coating.The protective coating is firmly combined with matrix, is difficult to peel off enamel coating with hand, and needing firmly to be tapped with hammer can shell
Remove the adamantine layer on surface.It can deduce and form metallurgical bonding between this coating and matrix at high temperature, therefore coating and base
Body is firmly combined, while paint coatings of the invention do not lose protecting effect, can also continue to using service life is longer.
Fig. 6 is the matrix metallographic structure figure after No. 2 sample corrosion, and the boundary tissue by observing sample can be seen that base
The boundary tissue and interior tissue of body be it is coherent and unconverted, there is no organizational hierarchy, phenomena such as coarse grains.This explanation
Matrix is not melted molten aluminum corrosion, is not influenced yet and aoxidizes by high temperature oxidative atmosphere, it was demonstrated that is of the invention
Coating protection works well, and the protective layer consistency of formation is high, can effectively obstruct the infiltration of aluminium atom and oxygen atom.
Weight loss data before and after 1, No. 2 sample corrosion test is compared, the results are shown in Table 1:
Table 1
Note: blank sample is to be not coated by the bare die of coating directly to carry out corrosion test under equivalent assay conditions
The corrosion rate of blank sample is maximum, and up to 2.5663 × 10-5g/(mm2H), and the corrosion rate of No. 2 samples is low
In the corrosion rate of No. 1 sample, corrosion rate is the 70.6% of No. 1 sample.In addition, photomacrograph in summary, microcosmic
The protecting effect of metallographic structure figure and comparison between corrosion, high temperature resistant molten aluminum etching ground of the invention is excellent, and traditional
" zinc oxide+waterglass " coating is compared, and corrosion rate is smaller, and the service life is longer, and economic benefit is higher.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
