Problems solved by technology

While this property has obvious benefits, it also allows thermal energy to be transferred into the consolidated material via conductive particles
This heat transfer leads to consolidation failure by softening or degrading the binder at the particle interface, thereby shortening the useful life of the bonded abrasive article

Embodiment 1

[0050] 200 / 230 mesh (according to ASTM (American Society for Testing and Materials) E11-04 standard) cubic boron nitride (cBN) particles (obtained from American Boarts Crushing, Boca Raton, Florida, U.S.) were supplied to Russia Technical Institute of St. Petersburg (Technical Institute of St. Petersburg) to encapsulate it in Al 2 O 3 in. About forty grams of cBN is encapsulated in Al 2 O 3 in. Al on each cBN particle 2 O 3 The nominal thickness is about 200 nanometers.

[0051] Coated with Al 2 O 3 The cBN particles produced two ceramic-consolidated grinding wheels. The ceramic-consolidated grinding wheel is made by first making such a grinding wheel, wherein the grinding wheel contains: about 36% by volume coated with Al 2 O 3 Of cBN particles, about 16% by volume of glass powder (aluminum borosilicate, obtained from SuperAbrasiveTechniques in Westerville, Ohio, USA, trade name "NON-LEADED GLASS FG2349"), about 14% by volume of hollow ceramic beads (Obtained from PQ Company, Val...

Embodiment 2

[0054] Prepare two ceramic-consolidated grinding wheels of Example 2 according to the method described in Example 1. The difference lies in the Al on each cBN particle 2 O 3 The nominal thickness is about 100 nanometers.

Embodiment 3

[0056] Prepare two ceramic-consolidated grinding wheels of Example 3 according to the method described in Example 1, except that TiO is applied 2 Coating instead of Al 2 O 3 coating.

Abstract

Composite particle having an abrasive grit with a ceramic material thereon. Composite particles can be incorporated, for example, into a variety of abrasive articles.

Description

Background technique [0001] Consolidated (usually metal-consolidated, resin-consolidated, and ceramic-consolidated) abrasive articles (eg, grinding wheels) are often used to grind the surface of a workpiece (eg, metal, plastic, and ceramic). These consolidated abrasive products are made using a variety of abrasive particles, including extremely hard abrasive particles sometimes referred to as "super abrasive" (eg, cubic boron nitride (CBN) and diamond) particles or abrasive particles . Such super-hard abrasive particles have relatively high thermal conductivity (usually at least about 0.03 cal / sec / cm / °C). Therefore, the super-hard abrasive particles are advantageously used in the grinding process that requires the heat generated during the process to be conducted away from the workpiece interface. Although this feature has obvious benefits, it also allows thermal energy to be transferred to the consolidated material via conductive particles. This heat transfer causes consolidation...
