Abstract
The invention discloses an anticorrosive ship side plate with a ceramic-based hot spray coating. The side plate comprises a gray cast iron matrix and the ceramic-based hot spray coating, wherein the ceramic-based hot spray coating is compounded on the outer surface of the gray cast iron matrix and sprayed by using supersonic and resists seawater corrosion. The SiC ceramic in the ceramic-based hot spray coating is distributed uniformly, and the volume fraction of ceramic powder can reach 75 percent; and the ceramic-based hot spray coating and the gray cast iron matrix are in metallurgical bonding, so that the coating is not fragmented or does not fall; and the corrosion resistance of the side plate is over 5 times that of a gray cast iron side plate, the surface of which is coated with an anti-corrosive paint.
Description
?
Technical field
The present invention relates to side plate peculiar to vessel field, specifically is a kind of side plate corrosion-resistant peculiar to vessel with ceramic base hot spray coating.
Technical background
The equipment corrosion of steelwork under the oceanic climate environment, especially the etching problem under mal-conditions such as seawater and high temperature, high humidity, high smog, high sunshine becomes increasingly conspicuous, and the destruction of causing because of corrosion happens occasionally.Adopting suffering-corrosive protection of aluminium alloy coating is one of effective ways of corrosion of steel structure protection, and in practical application, zinc-aluminum coating must adopt the synthetic paint sealing treatment, is used to stop the gap corrosion that connects with steel matrix to produce.Simultaneously, this type coating system is responsive especially to spot corrosion and physical abuse, makes corrosion protection coating system poor reliability.
The graphitic cast iron of external coating corrosion resistant coating side plate peculiar to vessel, the outer shell corrosion of planking starboard cargo hold is more serious usually, 40% pit corrosion; Top deck, quarter deck corrosion are serious, coating foaming, peel off; Defective such as weld seam corrosion aliquation between stem and stem shell plating.
No matter be that equipment configuration steel surface cast-infiltration zinc peculiar to vessel-aluminium is cast infiltration layer or graphitic cast iron side plate peculiar to vessel is coated with anticorrosion with coat; Side plate peculiar to vessel is military service surface peeling, bubbling, seriously corroded under ocean environment, in general the corrosion resistance nature of side plate peculiar to vessel relatively poor, work-ing life defective such as low and poor reliability.
Summary of the invention
The purpose of this invention is to provide a kind of side plate corrosion-resistant peculiar to vessel with ceramic base hot spray coating; The ceramic base hot spray coating of its copper, aluminium, chromium and rare earth mixed powder coating ceramic significantly improves the equipment protection against corrosion life-span of steelwork under ocean severe condition such as high temperature, high humidity, high salt fog.
A kind of side plate corrosion-resistant peculiar to vessel with ceramic base hot spray coating; Comprise graphitic cast iron matrix and the ceramic base hot spray coating that is compound in the supersonic spray coating seawater corrosion resistance of gray cast-iron based external surface; Its preparation is to be coated to SiC ceramic powder surface with copper, aluminium, chromium and rare earth mixed powder ball mill mixing earlier; Spray to gray cast-iron based external surface with supersonic spray coating method again, soak into hole sealing coating with high-temperature resistant hole sealing agent at last.
The ceramic base hot spray coating coats high xantal rare earth alloy by SiC ceramics powder surface to be formed, and adopts hot spray method to spray on the graphitic cast iron surface, and SiC is evenly distributed in high aluminum bronze coating, and SiC content is up to 75%.
The thickness of described ceramic base hot spray coating is 1mm.
Described ceramic base hot spray coating and graphitic cast iron matrix are metallurgical binding.
The aluminium content of described ceramic base hot spray coating in high xantal up to 13%.
SiC ceramic powder volume content is up to 75% in the ceramic base hot spray coating, and the coating corrosion resistance nature is high, and corrosion-resistant rate is that general graphitic cast iron surface of side plate painted peculiar to vessel is more than 5 times.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
See Fig. 1, a kind of side plate corrosion-resistant peculiar to vessel with ceramic base hot spray coating comprises graphitic cast iron matrix 2 and the ceramic base hot spray coating 1 that is compound in the supersonic spray coating seawater corrosion resistance of graphitic cast iron matrix 2 outside surfaces.
The ceramic base hot spray coating coats high xantal rare earth alloy by SiC ceramics powder surface to be formed, and adopts hot spray method to spray on the graphitic cast iron surface, and SiC is evenly distributed in high aluminum bronze coating, and SiC content is up to 75%.
Side plate matrix adopting graphitic cast iron casting, castmethod can adopt sand mold casting or permanent mold casting.Cast(ing) surface is removed oxide on surface through sandblast, forms certain coarse pretreating surface.
Preparing method of the present invention: ceramic powder and cupric, chromium, aluminium and the slaking of rare earth mixed powder ball mill mixing; Make cupric, chromium, aluminium and rare earth mixed powder powder coated to the ceramic powder surface; The method that adopts thermospray the ceramic base powder spraying to the graphitic cast iron matrix; Adopt hole sealing agent to soak hole sealing coating at last, form fine and close top coat.Hot spray coating after coating forms has seawater corrosion resistance, marine climate resistant corrosion characteristics, particularly its corrosion resistance well, and coating is soaked to accomplish after 160 hours in artificial seawater and is not corroded.
The thermal etching characteristic that the coating assessment is equipped down with reference to ocean environment, the present invention has examined coating hot corrosion resistance under 450 ℃ of high temperature in oxidation, chlorination, vulcanized gas respectively through experiment, simultaneously with graphitic cast iron matrix and control sample of the present invention; Thermospray single coating thickness is 1mm, and test is carried out in air resistance furnace, the every electronic-weighing that utilized at a distance from 10 hours of sample; Except that the oxidation corrosion test; After other two kinds of corrosion tests all need spray corrosion reagent, together put back in the stove heating with the sample of oxidation corrosion and weigh, record is weighed and is carried out next week test again after the data; Test is carried out 20 cycles altogether; Wherein, 5%NaCl aqueous solution spray is adopted in the chlorination test, and it is the Na of 7:3 that mol ratio is adopted in the sulfuration test
