What are the common surface treatment methods in industrial ceramic processing?
The common surface treatment methods in industrial ceramic processing are mainly as follows:
Mechanical surface treatment
By mechanical means, such as grinding, grinding, polishing, etc., the ceramic surface is processed to improve its surface roughness, flatness and finish. Mechanical surface treatment methods include grinding, grinding, polishing, sandblasting, etc. These methods can remove the defects and impurities on the ceramic surface, improve its surface quality, and meet the needs of subsequent processing or use.
Chemical surface treatment: The ceramic surface is treated by means of chemical reaction or caustic agent to change the chemical properties and composition of its surface. Chemical surface treatment methods include pickling, oxidation, reduction, formation, etc. These methods can change the wettability, adhesion and frictional properties of ceramic surfaces to meet the needs of specific applications.
Heat treatment surface treatment: by heating or heat treatment means, change the microstructure and phase composition of the ceramic surface to improve its mechanical properties and heat resistance. Heat treatment surface treatment methods include quenching, tempering, annealing, etc. These methods can change the hardness and toughness of the ceramic surface, improve its wear resistance and impact resistance, and make it suitable for high temperature and high strength environments.
Surface coating treatment: Coating a ceramic surface with one or more layers of other materials to change its surface properties and functions. Surface coating treatment methods include coating, plating, sputtering, etc. These methods can change the optical properties, electrical properties and chemical properties of the ceramic surface, so that it has the required anti-corrosion, anti-oxidation, conductive, insulating and other functions.
In practical applications, it is necessary to choose the appropriate surface treatment method according to the specific requirements and application scenarios of industrial ceramics. Different surface treatment methods can be used alone or in combination to achieve the desired surface quality and functionality. At the same time, the quality and effect of surface treatment are also affected by factors such as raw material quality, equipment accuracy and process parameters, so quality control and parameter optimization are required in actual operation.

Mechanical treatment: By mechanical means, such as grinding, grinding, polishing, etc., on the surface of ceramic materials to improve the surface finish and surface topography. Among them, grinding can be divided into wet grinding, dry grinding and semi-dry grinding three types. Polishing is the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.
Chemical treatment: Through chemical solvents, corrosives and surfactants, certain treatment is applied on the ceramic surface to improve the corrosion resistance, wear resistance and heat resistance of the surface.
Heat treatment: Apply a certain heat treatment to the ceramic material to improve the mechanical properties of the ceramic, such as increasing the toughness and strength of the material.
Surface coating: Apply a certain coating on the surface of the ceramic to improve the corrosion resistance, wear resistance and heat resistance of the ceramic material.
Ultrasonic machining: The use of ultrasonic vibration of the tool end face impact in the working fluid suspended abrasive, by the abrasive impact on the surface of the workpiece to achieve the workpiece surface treatment method.
Laser processing: A surface treatment method that uses the energy of light to reach a high energy density at the focus after the lens is focused, and relies on the photothermal effect to process.
In the surface treatment of industrial ceramic processing, attention needs to be paid to selecting the appropriate surface treatment method. According to the requirements of the ceramic surface, different surface treatment methods are selected to ensure that the treated surface has a good finish and surface structure. At the same time, it is also necessary to pay attention to the process of ceramic surface treatment, such as temperature, time, concentration, etc., and the selection of these parameters should meet the requirements of surface treatment to ensure the quality of surface treatment.
