Description

The preparation method of the sintering enamelled coating of the compound slurry of the nanometer enamel of surface of low-carbon steel and Its hot rolling treatment
Technical field
The present invention relates to a kind of preparations applied to quiet steel nano enamel slurry corrosion-resistant finishes and corresponding hot rolling to add Work technology belongs to nanometer slurry sinter coating technology and hot rolling treatment technical field.
Background technique
The sintering enamelled coating of nanometer slurry be nanotechnology with plasma spray technology effectively in conjunction with and generate one is more new The technology of grain husk is further extension and expansion after micron powder spraying technology, but due to the skin effect of nano-powder, small ruler Very little effect, high energy efficiency should wait properties, have more excellent and unique performance compared with micron particles, so nanometer slurry is sintered It is that new new technology is started in completely new having that enamel coating technology, which can also be said, at home and abroad has a large amount of scientific research at present Personnel and scientific research institution start that the preparation of the sintering enamelled coating of nanometer slurry and post-processing technology are explored and studied, at present In the mainly Thermal Barrier Coating Technologies that this facilitates research more, and in anti-corrosion nano enamel coating especially metal alloy corrosion resistant Research is still less in terms of losing nanometer enamel coating.
Hole, crackle and structure it is loose uneven the defects of be plasma-coated at present existing one and biggish ask Topic, there is presently no good methods can solve this problem, and the nanometer slurry from current thermal barrier coating field is sintering enamelled From the point of view of the case where coating, hole, crackle and the non-uniform situation of short texture have apparent improvement compared with micron powder coating, But this problem still has in the sintering enamelled coating of nanometer slurry, and in the reality of nanometer enamel fused slurry enamel coating Obviously revealed in application process, this to the sintering enamelled coating of nanometer slurry industrialized production popularization practical by very big Limitation, especially enamel coating is more obvious in corrosion resistant application aspect, and the presence of hole and crackle can be such that corrosive deposit wears Open-work hole and crackle and directly contacted with matrix, so that protective coating be made to fail.So effectively reducing the hole in coating and splitting Line is nanometer slurry sintering paint-on technique field urgent problem to be solved.
Summary of the invention
The present invention prepares hole and the porosity by preparation and hot rolling treatment to nanometer enamel fused slurry coating It is few, the corrosion resistant enamel coating of compact and uniform structure.In the preparation of coating and coating procedure, the present invention carries out enamel composition Depth profiling can effectively solve glaze and matrix during the application of slip and combine untight ask by the way that 1 ~ 3% binder is added Topic.The good diopside phase of corrosion resistance is obtained by the proportion between control raw mineral materials simultaneously, furthermore passes through control Na2O And B2O3Amount be sintered boron oxygen triangle body close packed structure and reduce the intrinsic porous amorphous structure of enamel layer.Meanwhile the present invention Nanosizing is carried out to enamel particle by long-time ball milling.The characteristic small using the particle size of nano-powder, energy is high is effective The hole and crackle of fused slurry coating are reduced, the compactness and uniformity for improving coating make coating using material hot rolling technology Structure more dense uniform, hole under the crunch effect of roll-force is further reduced.
The present invention proposes a kind of preparation method of nano combined fused slurry enamel coating of surface of low-carbon steel, it is characterised in that With following process and step:
A. use the compositing formula of enamel powder for (wt.%): 55.26SiO2, 6.59Al2O3, 8.56ZnO, 8.12B2O3, 4.96Na2O, 10.77CaO, 2.24MgO and 1 ~ 3CeO.
B. powder ball milling: the dry ball milling of 80 ~ 200h is passed through to the enamel powder that preparation is completed celestial body grinding machine of being expert at, is connect Get off to add the wet ball grinding process that the grinding aids such as ethyl alcohol carry out 200h, next ball and material is separated, finally as drying Machine drying；
C. prepare coating slurry: by the nano-scale particle of above-mentioned milled, (i.e. the diameter of these particles is tens to several hundred Between nanometer), there is certain glue wherein adding a certain amount of cobalt oxide and preparing there are also the ethyl alcohol of nickel oxide and addition 10% The slurry of degree, so as to directly as sintering coating material；Specific method is 1 ~ 1.5% will to be added in nanometer enamel powder to stick Soil and ethyl alcohol and 0.5%NiO+1.5%CoO binder, make it be mixed into jelly, the volume of solid matter point in jelly Number is 75 ~ 95%；10 ~ 35min is stirred to jelly using mechanical mixing method under conditions of 50 ~ 70 DEG C；It can be prepared by slurry；
D. surface coating and green body production: the surface that slurry is uniformly coated in mild steel is taken out after stirring, is connect It is put into drying box and dries 20 ~ 50min；One layer of uniform coating has just been obtained in specimen surface in this way, has obtained so-called green body；
E. sample is sintered: and then the idiosome prepared is placed in Muffle furnace and is sintered, temperature is 750 ~ 900 DEG C, sintering Time is that 15 ~ 60min obtains uniform enamel coating；
F. hot rolling treatment: setting start rolling temperature are as follows: 300 ~ 980 DEG C, total rolling is than being 10 ~ 30%, using 3 ~ 5 passages reality Now sample is kept the temperature 30min under start rolling temperature first, keeps sample temperature uniform by whole drafts before rolling starts；Rolling After sample be placed in high temperature process furnances under hydrogen atmosphere make annealing treatment, annealing temperature is 500 ~ 900 DEG C, annealing knot Sample furnace cooling after beam.
The present invention has a characteristic that
1, of the invention by the way that by nanotechnology, Glaze Composition control and material hot rolling technique effectively orderly combine, and Its respective advantage is made full use of, there is small-size effect, skin effect and high energy efficiency should wait special performances, warding off for nano-powder It in porcelain coating procedure, combines more closely, more uniformly spreads between particle, to effectively reduce the hole in coating and split Line, the proportion of Glaze Composition are capable of the phase composition of Effective Regulation sintered product, until with excellent corrosion resistance object mutually simultaneously And generate the phase structure of even compact.In course of hot rolling, since by the crunch rolled, coat inside structure is slightly variable Shape keeps coating structure more fine and close, is heat-treated under hydrogen state to sample after rolling, carries out sufficiently to sample Interpenetrated atom in coating in the case where reduction, to keep coating structure more uniform.
2, the present invention can produce hole and crackle is few by a series of coherent techniques, and outstanding milkiness is excellent, compact structure The uniform nanometer enamel coating of ingredient.The invention also can be suitable for receiving using other metal materials as matrix by the adjustment of parameter The preparation of riceization coating.
3, present invention process is coherent, effect is obvious, no pollution to the environment, but because current nano-powder technology of preparing into Step, nano-powder cost reduces, so the present invention is suitable for very much industrializing expanding production.
