Description
Technical Field
The invention relates to a composite material, in particular to a steel pipe lined with ceramic.
Background
The current compounding methods of metal materials and inorganic non-metal materials mainly comprise a self-propagating high-temperature synthesis method, a thermal spraying method, physical vapor deposition, chemical vapor deposition, enamel and the like.
The self-propagating high-temperature synthesis method is a new process for preparing boride, carbide, nitride, silicide and intermetallic compound materials by maintaining self-propagation of combustion waves by using an exothermic reaction between raw materials, and was originally invented by a.g. merzhanov et al, russian chemico-physical research institute. Since the self-propagating high-temperature synthesis technology is generated, the foreign countries have made great progress on material preparation processes and equipment, and materials such as TiB2, TiC, MoSi2 and the like are successfully produced in large quantities by adopting the technology, and the technology is the most advanced in Russia and the technology level in the United states. However, the synthesis process has serious environmental pollution, the technological process is difficult to control, the product porosity is high, the inorganic non-metallic material layer is always cracked, and the potential cracking risk exists. Therefore, the product can be used for wear resistance, but is difficult to be used for corrosion prevention.
The thermal spraying method of inorganic nonmetallic materials refers to a series of processes in which finely dispersed inorganic nonmetallic coating materials are deposited in a molten or semi-molten state on a prepared substrate surface to form a certain sprayed deposition layer. It is a technique that inorganic non-metal powder or inorganic non-metal material is heated to molten or semi-molten state by using a certain heat source (such as electric arc, plasma spraying or combustion flame, etc.), and then sprayed onto the surface of the pretreated substrate at a certain speed by means of flame flow itself or compressed air, and deposited to form surface coatings with various functions. This technique has no potential risk of cracking relative to self-propagating high temperature synthesis, but has higher porosity and very low bond strength. The corrosion resistance and the wear resistance of the material are general, and the characteristic of stronger performance of inorganic non-metallic materials is difficult to develop.
Physical vapor deposition and chemical vapor deposition can form a layer of dense inorganic non-metallic material film on the surface of the substrate, but the cost is very high, and the method is not suitable for mass production.
The enamel is inorganic glass enamel coated on the surface of a metal base blank. The enamel coating on the metal surface can prevent the metal from rusting, so that the metal can not form an oxide layer on the surface when being heated and can resist the corrosion of various liquids. The enamel product is safe, non-toxic, easy to wash and clean, and may be used widely as diet utensil and washing utensil in daily life. The enamel layer can also endow the product with beautiful appearance and serve people's life. Therefore, the enamel product has both the strength of metal, the gorgeous appearance of the enamel and the performance of chemical erosion resistance. However, enamel products are becoming more and more rare in recent years, mainly because the surface enamel layer is easily broken, cracks are easily generated when products with larger volume are made, and the like, especially when the thermal expansion coefficient of the enamel is far from that of the metal material of the base layer.
How to overcome the defects of the various schemes can form a layer of compact and uniform inorganic non-metallic material layer with high toughness and strength, particularly a ceramic layer, an enamel layer, a glass layer, a glaze layer and the like on the surface of metal, so that the inorganic non-metallic material layer has wear resistance, corrosion resistance and certain thermal shock resistance and shock resistance, and is a problem to be solved urgently.
The present application thus proposes a completely new, very economical and high-quality solution for depositing a layer of inorganic, non-metallic material, such as ceramic, on metal pipes and sheets.
