Ceramic particle coating method and composite material preparation method
The invention provides a method for coating ceramic particles and a preparation method of a composite material. The coating method comprises the following steps: mixing ceramic particles with an adhesive, adding coating powder, and stirring to obtain ceramic particles coated with the coating powder; mixing the ceramic particles coated with the coating powder with polyvinyl alcohol, and drying to obtain ceramic particles with the coating powder and the polyvinyl alcohol attached to the surfaces; and activating the ceramic particles of which the surfaces are attached with the coating powder and the polyvinyl alcohol, and carrying out chemical plating by using a plating solution after activation to obtain the ceramic particles coated with the coating powder-metal coating. The preparation method of the composite material comprises the following steps: preparing coating powder-metal coating coated ceramic particles; and carrying out pressureless infiltration treatment on the ceramic particles coated with the coating powder-metal coating and the metal matrix to obtain the composite material. According to the method, the surfaces of the ceramic particles can be better coated with the coating powder through the protection layer formed by the polyvinyl alcohol, a reaction type interface can be better formed in the compounding process of the ceramic particles and a metal matrix, and the bonding performance is better.
本发明提供了一种包覆陶瓷颗粒的方法及复合材料制备方法。包覆方法包括：将陶瓷颗粒与粘接剂混合，加入包覆粉，搅拌后得到包覆粉包覆的陶瓷颗粒；将包覆粉包覆的陶瓷颗粒与聚乙烯醇混合，干燥后得到表面附着包覆粉与聚乙烯醇的陶瓷颗粒；对表面附着包覆粉与聚乙烯醇的陶瓷颗粒进行活化，活化后利用镀液进行化学镀，得到包覆粉‑金属镀层包覆的陶瓷颗粒。复合材料制备方法包括：制备包覆粉‑金属镀层包覆的陶瓷颗粒；对包覆粉‑金属镀层包覆的陶瓷颗粒与金属基进行无压浸渗处理得到复合材料。本发明方法利用聚乙烯醇形成的保护层能够使包覆粉更好的包覆在陶瓷颗粒表面，能够使陶瓷颗粒与金属基的复合过程中更好地形成反应型界面，结合性能更好。
