Title (EN) NICKEL-PLATED SILICON CARBIDE PARTICLES AND PREPARATION METHOD THEREFOR
(FR) PARTICULES DE CARBURE DE SILICIUM NICKELÉES ET LEUR PROCÉDÉ DE PRÉPARATION
(ZH) 一种镀镍碳化硅颗粒及其制备方法
Abstract:
(EN) A preparation method for nickel-plated silicon carbide particles, comprising the following steps: step I: activating silicon carbide particles; step II: performing washing, filtering, and drying; step III: performing chemical nickel plating; and step IV: performing washing, filtering, and drying. Silicon carbide particles having a particular particle size are selected, and coating and nickel plating are performed on the surfaces of the silicon carbide particles by a method comprising cleaning, activation treatment, and nickel plating with a particular solution, so that the surfaces of the silicon carbide particles are uniformly attached with nickel, thereby improving the uniform fusion degree between silicon carbide and a metallic material, avoiding the problems of segregation and cracking of a composite material, and improving the yield of the composite material.
(FR) Cette invention concerne un procédé de préparation de particules de carbure de silicium nickelées, comprenant les étapes suivantes : étape I : activation de particules de carbure de silicium; étape II : réalisation d'un lavage, d'un filtrage et d'un séchage; étape III : réalisation d'un dépôt chimique de nickel; et étape IV : réalisation d'un lavage, d'un filtrage et d'un séchage. Des particules de carbure de silicium ayant une taille de particule particulière sont sélectionnées, et un revêtement et un placage de nickel sont réalisés sur les surfaces des particules de carbure de silicium par un procédé comprenant le nettoyage, le traitement d'activation et le placage de nickel avec une solution particulière, de sorte que le nickel soit uniformément fixé sur les surfaces des particules de carbure de silicium, ce qui permet d'améliorer le degré de fusion uniforme entre le carbure de silicium et un matériau métallique, évitant les problèmes de ségrégation et de fissuration d'un matériau composite, et améliorant le rendement du matériau composite.
(ZH) 一种镀镍碳化硅颗粒的制备方法,其包括以下步骤:步骤一:活化碳化硅颗粒;步骤二:洗涤、过滤并烘干;步骤三:化学镀镍;步骤四:洗涤、过滤并烘干。选取一定粒径的碳化硅颗粒,通过清洗-活化处理-特定溶液镀镍的方法,将碳化硅颗粒表面进行涂层、镀镍,使碳化硅颗粒表面均匀附着镍,从而提高碳化硅与金属材料的均匀融合程度,避免出现复合材料的偏析与龟裂问题,提高复合材料的成材率。
