Title (EN) SHAPED ABRASIVE PARTICLES WITH SHARP TIPS
(FR) PARTICULES ABRASIVES PROFILÉES À EXTRÉMITÉS POINTUES
Abstract: front page image
(EN)Various embodiments disclosed relate to shaped abrasive particles having sharp tips, methods of making the shaped abrasive particles, methods of abrading a substrate with the shaped abrasive particles, and coated abrasive articles including the shaped abrasive particles. The shaped abrasive particle includes a ceramic, has a polygonal cross-sectional shape along a longitudinal axis of the shaped abrasive particle, and at least one tip of the shaped abrasive particle has a radius of curvature of less than or equal to about 19.2 microns.
(FR)La présente invention concerne divers modes de réalisation de particules abrasives profilées ayant des extrémités pointues, des procédés de fabrication de particules abrasives profilées, des procédés d’abrasion d’un substrat avec les particules abrasives profilées, et des articles abrasifs enduits comprenant les particules abrasives profilées. La particule abrasive profilée comprend une céramique, présente une forme transversale polygonale dans le sens de l'axe longitudinal de la particule abrasive profilée, et au moins une extrémité de la particule abrasive profilée possède un rayon de courbure inférieur ou égal à environ 19,2 microns.
