Abstract:
An abrasive particle includes a body having at least one microstructural characteristic including average crystal size of not greater than 6 microns or a hardness of at least 20 GPa, and wherein the body further has at least one deformation characteristic including a primary deformation amplitude of not greater than 30 percent, a primary deformation time of not greater than 280 minutes, or a secondary deformation characteristic rate of not greater than 6x10-3 percent/minute.
Abstract:
An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.
Abstract:
An abrasive article includes a body having abrasive particles contained within a bond material. The abrasive particles can include a majority content of silicon nitride and a minority content of sintering material including at least two rare-earth oxide materials. In an embodiment, the rare-earth oxide materials can include Nd2O3 and Y2O3. In a particular embodiment, the abrasive particles comprise a content (wt%) of Nd2O3 that is greater than a content of Y2O3 (wt%).

Abstract:
An abrasive tool including a bonded abrasive article including a bond material comprising a metal or metal alloy, abrasive grains contained within the bond material, and a reaction agent dispersed within the bond material, wherein the reaction agent chemically reacting with a surface of the workpiece during abrasion to form a reaction product.
Abstract:
An abrasive comprising shaped abrasive particles each with an opening. The shaped abrasive particles are formed from alpha alumina and have a first face and a second face separated by a thickness t. The opening in each of the shaped abrasive particles can improve grinding performance by reducing the size of a resulting wear flat, can provide a reservoir for grinding aid, and can improve adhesion to a backing in a coated abrasive article.
Abstract:
The invention relates to a method for producing A12O3/SiC nanocomposite abrasive grains. SiC nanoparticles are added to a sol containing aluminium oxide and said sol is then gelatinized, dried, calcinated and sintered. The invention also relates to A12O3/SiC nanocomposite abrasive grains.
