Abstract
PARTÍCULA ABRASIVA INCLUINDO REVESTIMENTO, ARTIGO ABRASIVO INCLUINDO AS PARTÍCULAS ABRASIVAS E MÉTODO DE FORMAÇÃO. Uma partícula abrasiva pode incluir um revestimento que sobrepõe pelo menos uma porção de um núcleo. Em uma modalidade, o revestimento pode incluir uma primeira porção que sobrepõe pelo menos uma porção do núcleo e uma segunda porção que sobrepõe pelo menos uma porção do núcleo, em que a primeira porção pode incluir um material cerâmico e a segunda porção pode incluir um silano ou um produto de reação de silano. Em uma modalidade particular, a primeira porção pode consistir essencialmente em sílica. Em outra modalidade particular, a primeira porção pode incluir uma rugosidade de superfície não superior a 5 nm e um teor cristalino superior a 60%.
