Description

The composite ceramic and the preparation of wearing and tearing of used for hot spraying anti-seawater corrosion and biodeterioration
Technical field
The present invention relates to a kind of material that is used for the Surface Engineering of thermospray, particularly relate to the Conglobation type anti-seawater corrosion wearing and tearing that are used for hot-spraying techniques and the composite ceramic and the preparation method of biodeterioration.
Background technology
In 21 century, along with people to the energy development of marine field and the expansion of scope of activity, increasing reciprocating part begins to be applied under the ocean environment, but the corrodibility of seawater, microorganism are stained etc. the device under the seawater Working environment is all produced a very large impact.The use heat spraying technology sprays one deck composite ceramic coat on metallic matrix, both overcome metal resistance to corrosion seawater difference and the big shortcoming of brittleness of ceramics, can give full play to the rigidity of metal and the good anti-corrosion wear of pottery again.The high rigidity of ceramic coating, high rigidity, high elastic coefficient make ceramic coating have excellent performances such as wear-resistant, corrosion-resistant, anti-cavitation erosion; Can prepare fine and close ceramic coating by improving raw material and process for refining, reduce porosity, be more suitable in briny environment, working; Oxide-based stupalith can reduce the frictional coefficient of to-and-fro movement device greatly owing to the easy adsorbed film of water of polarized action; A spot of hole in the ceramic coating is good containment structures, can keep the continuity of water lubricating film to exist in to-and-fro movement.
But ceramic coating is applied to need in the briny environment to solve emphatically following problem:
1. bonding strength.Because reciprocating part not only bears very high contact stress, also can bear vibratory impulse to a certain degree, if bonding strength is low, coating shedding often occurs or peel off.
2. the suitability of body material and coated material.Whether the linear expansivity and the thermal conductivity that mainly are pairing material be close, differs when too greatly then the working in reciprocating mode part is subjected to thermal shocking and can produce thermal stresses on bonding interface.
3. compactness.Plasma spraying is that the ceramic powder that will be the fine droplet shape under molten state impacts on the matrix surface with high speed, become the pancake shape, accumulate synergetic process layer by layer, therefore produce many small pores in the coating forming procedure, when coating is thin, often there is the passage from the coatingsurface to the bonding surface in the passage that the interconnection formation of many pores is tiny inevitably, the corrosion of interfacial layer in having corrosive water, occurs, weaken bonding strength even cause that the part peels off.
4. the control of various tissue defects in the coating, as be mingled with micro-crack etc.
5. make the adaptability difficult problem of medium with water conservancy project.The water particularly corrodibility of seawater is strong, has comprised a large amount of organism, microorganism, metal and nonmetallic ion in the seawater, and chloride ion content is big, and seawater is natural ionogen.
There is data to show SiC, Si 3N 4, Sialon, Al 2O 3Be suitable for doing to-and-fro movement material under the briny environment Deng all, still because SiC, Si 3N 4In Plasma Spraying Process Using, have serious oxidation, can not guarantee the composition of coating, so and be not suitable for thermospray; can only consider vapour deposition or laser remolten; if adopt other prepared ceramic coating of non-thermospray, production cost is significantly improved, can't mass-producing use.Sialon is Si 3N 4The middle Al that adds 2O 3, Al in sintering process 2O 3Solid solution is in Si 3N 4Form, can only consider to manufacture integral member, adopt single ceramic material reciprocating part can't overcome the stupalith inherent defect.Japan DSRV sea-water pump cylinder bore lined ceramics Al 2O 3Plasma spraying; The plunger of Kawasaki Heavy Industries sea water plunger pump is the molten pottery of annotating of stainless steel surface; Domestic research unit such as Zhejiang University's fluid transmission and control National Key Laboratory adopt Al 2O 3+ 13%TiO 2Preparation ceramic coating working element, though reach requirement substantially at dynamic performance, the stained and anti-seawater corrosion polishing machine of microorganism requires barely satisfactoryly in anti-sealing, its weather resistance that is applied to real work is still waiting perfect.Domestic and international ceramic coating working element multiselect oxide ceramic powder under the briny environment, but its ceramic powder select for use and composite ceramic between the ratio of each component inclined to one side mistake is arranged more, do not add any stained composition of microorganism in the sealing of effectively preventing simultaneously; Even part has been added the anti-biofouling composition, but the fouling resistance composition of its interpolation may contaminate environment.Use new problem and the task of having proposed therefore for the research of the preparation raw material of the ceramic coating reciprocating part in the briny environment.By on the basis of choose reasonable anti-seawater corrosion wearing and tearing raw material, the trace interpolation addresses the above problem the component that environment does not have the anti-biofouling of harm this patent just.
Summary of the invention
Technical problem to be solved by this invention is: composite ceramic and preparation method that a kind of used for hot spraying anti-seawater corrosion wearing and tearing and biodeterioration are provided, this composite ceramic is a kind of ceramic powder that preparation traditional ceramics coating is used that is different from, performance with the wearing and tearing of significant anti-biofouling and seawater corrosion resistance, be suitable for plasma spraying or flame plating technology, this composite ceramics powder preparation technique is simple simultaneously, cost is low and be beneficial to suitability for industrialized production.
