    Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. An abrasive article preform is produced by an additive manufacturing sub-process comprising the deposition of a layer of loose powder particles in a confined region and selective heating via conduction or irradiation to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The abrasive article preform produced by additive manufacturing is subsequently heated to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. Also, the methods include receiving, by an additive manufacturing device having a processor, a digital object specifying data for an abrasive article, and generating the abrasive article with the manufacturing device.

    Abstract: Al 2 O 3 -La 2 O 3 -Y 2 O 3 -MgO ceramics (including glasses, crystalline ceramics, and glass-ceramics) and methods of making the same. Ceramics according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. The particles and fibers are useful, for example, as thermal insulation, filler, or reinforcing material in composites (e.g., ceramic, metal, or polymeric matrix composites). The thin coatings can be useful, for example, as protective coatings in applications involving wear, as well as for thermal management. Some embodiments of ceramic particles according to the present invention can be are particularly useful as abrasive particles.

    Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. The methods include sequential steps. Step a) includes a subprocess including sequentially: i) depositing a layer of loose powder particles in a confined region; and ii) selectively applying heat via conduction or irradiation, to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The layer of loose powder particles has substantially uniform thickness. Step b) includes independently carrying out step a) a number of times to generate an abrasive article preform comprising the bonded powder particles and remaining loose powder particles. Step c) includes separating remaining loose powder particles from the abrasive article preform. Step d) includes heating the abrasive article preform to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. A method of making a metal bond abrasive optionally includes infusing an abrasive article preform with a molten lower melting metal and solidifying the molten lower melting metal to provide the metal bond abrasive article. The present disclosure further provides a vitreous bond abrasive article precursor and a metal bond abrasive article precursor.
