Title (EN) ABRASIVE PARTICLES HAVING COATINGS WITH TORTUOUS SURFACE TOPOGRAPHY
(FR) PARTICULES ABRASIVES PRESENTANT DES REVETEMENTS A TOPOGRAPHIE SUPERFICIELLE SINUEUSE
Abstract: front page image
(EN)The present invention relates to abrasive composites having improved abrasive particle (10) retention due to unique coating designs. The present invention describes coated abrasive particles (10) having tortuous surface topography, a process for producing such coated abrasive particles, and products comprising such coated abrasive particles. The coated abrasive particles (10) have an outer layer coating with highly tortuous surface comprising about 5 spikes (20) and have a tortuosity of at least about 1.1. The coated abrasive particles (10) may be used in composites including metal/metal alloy matrix composites, ceramic/glass matrix composites, and polymer based matrix composites.
(FR)L'invention concerne des composites abrasifs à capacité renforcée de rétention de particules abrasives (10), due à des conceptions de revêtement uniques. L'invention concerne des particules abrasives (10) enrobées et présentant une topographie superficielle sinueuse, un procédé permettant de produire des particules abrasives ainsi enrobées et des produits comprenant de telles particules abrasives enrobées. Les particules abrasives enrobées (10) présentent un revêtement de couche extérieure à surface sinueuse comprenant approximativement 5 pointes (20) et présentant une sinuosité d'au moins approximativement 1,1. Les particules abrasives enrobées (10) s'utilisent dans des composites incluant des composites à matrice d'alliage métal/métal, des composites à matrice céramique/verre et des composites à matrice à base de polymères.
