Abstract:
An abrasive article includes a first abrasive element, a second abrasive element, a resilient element having first and second major surfaces, and a carrier. The first element and the second abrasive element each comprises a first major surface and a second major surface. At least the first major surfaces of the first and second abrasive elements comprise a plurality of precisely shaped features. The abrasive elements comprise substantially inorganic, monolithic structures.
Abstract:
An abrasive article includes a plurality of abrasive features disposed on one or more abrasive elements. Each of the one or more abrasive elements includes a base having a first major surface from which the plurality of abrasive features extends. A first set of the plurality of abrasive features (i) has an average height, H 1avg , (ii) a standard deviation of less than 10% of H 1avg , and (iii) comprises between 5 and 130 abrasive features.
Abstract:
An abrasive element includes a first major surface and a second major surface. At least the first major surface includes a plurality of precisely shaped features. The abrasive element includes at least about 99% of carbide ceramic by weight and has a porosity of less than about 5%.
