Description
Technical Field
The invention relates to the field of preparation of ceramic coatings by thermal spraying, in particular to a method for treating a suspension raw material used in a suspension plasma spraying method
Background
At present, many enterprises adopt a mode of spraying yttrium oxide on an aluminum substrate to enhance the corrosion resistance and the wear resistance of the aluminum substrate, but most of enterprises use powder raw materials to spray yttrium oxide, and the particle size of the powder raw materials is larger (40-60um), so that the generated coating has larger pores. This makes the inside of the coating easy to embed contaminating impurities and the acid base and plasma etc. are easy to break down from the pores. The direct use of low-nanometer powder material will result in insufficient fluidity and thus affect the spraying process. As integrated circuit nano-fabrication processes become finer and finer, the requirements for coating density and cleanliness will become higher and higher. Therefore, the plasma spraying is carried out by using the raw material of the suspension, and an efficient process mode is realized. However, the suspension raw material has many factors to affect the internal structure, size and agglomeration degree of the material, and the coating sprayed by the unstable raw material has fluctuation in performance.
Therefore, the suspension raw material pretreatment method used in the patent is to prepare submicron or nanometer powder (0.5-5um) into a solvent through a proper solvent, and the suspension after being deposited for a certain time is knocked and mixed uniformly by using tools such as a skin hammer and the like, and is rotated at a fixed rotating speed for a fixed time, and the suspension is reprocessed within a certain using time.
