An abrasive article including: a backing layer including a front fill overlying a backing, wherein the backing layer including the front fill comprises (1) a surface roughness of not greater than 100 microns or (2) an average thickness/roughness ratio of greater than 0.80; a make coat overlying the backing layer; and a plurality of abrasive particles overlying the backing layer, wherein at least 65% of the abrasive particles have a well-oriented tilt orientation.

Abrasive articles and methods of forming same

An abrasive article includes a backing; a make coat overlying the backing; and a plurality of abrasive particles overlying the backing and at least partially contained in the make coat; and a make coat thickness ratio (Tg/Ta) of not greater than 1.5, wherein Tg is the average thickness of the make coat at the sides of the abrasive particles and the Ta is the average thickness of the make coat.

An abrasive article including a backing; a plurality of shaped abrasive particles overlying the backing; where the abrasive article further has: 1) a Swarf Mode Gray Value of less than 25 for cumulative material removed of at least 500 g according to the Inconel Grinding Swarf Color Test; 2) a Maximum Swarf Mode Gray Value of less than 25 for a cumulative material removal of not greater than 700 g according to the Inconel Grinding Swarf Color Test; or 3) a combination of 1) and 2).

A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, wherein at least 5% of the plurality of abrasive particles is tooth-shaped abrasive particles.

A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, and the plurality of abrasive particles including tapered abrasive particles having a taper fraction standard deviation of at least 0.025 and not greater than 0.090.

An abrasive particle can include a coating overlying at least a portion of a core. In an embodiment, the coating can include a first portion overlying at least a portion of the core and a second portion overlying at least a portion of the core, wherein the first portion can include a ceramic material and the second portion can include a silane or a silane reaction product. In a particular embodiment, the first portion can consist essentially of silica. In another particular embodiment, the first portion can include a surface roughness of not greater than 5 nm and a crystalline content of not greater than 60%.
