Description
Technical field
The present invention relates to the preparation method that a kind of modified carbon fiber strengthens composite ceramics, belong to technical field of aluminum electrolysis.
Background technology
At present, the carbon annode material is still adopted in the conventional aluminum electrolysis, can discharge a large amount of greenhouse gases, contaminate environment in electrolytic process.And need the frequent anode material of changing, increase production cost.People are from energy-conservation and reduce production costs, and eliminate the electrolysis of aluminum pollution on the environment and set out, and Mathematical model has been produced some new designs.The investigator is being devoted to develop the aluminum electrolyzation technology that adopts the noble electrode system in the last thirty years, and its core is exactly the research of inert anode material.After the eighties in 20th century, the research of aluminum electrolysis inertia anode material mainly concentrates on metal anode, metal oxide anode, sintering metal anode.Metal anode is easy to make, and has good electroconductibility, therefore is considered always and makes the aluminium electrolysis anode material.But except some precious metal, metallic substance can not fully be resisted the oxygen corrosion of cryolite fused salt and electrolysis generation.Metal oxide is because unreactiveness receives much concern, but relatively poor electroconductibility and heat-shock resistance have limited again their application.Cermet material has been concentrated the unreactiveness of the good electron conduction of metallic substance and stupalith, so be considered to as the most promising material of inert anode always, the research of this respect is also maximum.But find in the electrolysis of aluminum experimental study, inert anode surface meeting produces a large amount of O
2Bubble, surface formed the gas shield film, stoped cryolite fused salt to the corrosion of inert anode and soaked into.Yet due to a large amount of O
2The fluctuation of bubble and electrolytic solution is washed away the inert anode surface, makes the ceramic matrix of cermet inert anode large-area cracking and slag-off phenomenon occur in electrolytic process, causes the electrolytic corrosion speed of inert anode material higher.Thereby the mechanical behavior under high temperature that how to improve the ceramic-base inert anode material becomes the key of inert anode research.
At present, the carbon fiber of employing high specific strength and high elastic coefficient has been subjected to the investigator mutually as ceramic toughening and has paid close attention to widely, and the interface performance of carbon fiber and ceramic matrix has determined the effect that fiber induces one, and affects to a great extent the fracture mode of matrix material.Often improve the interfacial state of carbon fiber and ceramic matrix by means of process for modifying surface such as high temperature oxidation alligatoring and metallizing coatings for this reason.But high-temperature oxidation process has greatly reduced original intensity of carbon fiber, and the wettability of metallic coating and ceramic matrix is bad, cause carbon fiber and ceramic matrix interface still to have more space, the suffered stress of ceramic matrix can not effectively be delivered on carbon fiber, so the mechanical property of ceramic matrix can not be improved.So, study a kind of coating technology oxide coated on carbon fiber, not reducing the original intensity of carbon fiber simultaneously is one of gordian technique of the carbon fiber-reinforced pottery of development.
