摘要： An abrasive article can include an abrasive component including a body. The body can include a bond matrix and abrasive particles contained in the bond matrix. In an embodiment, the body can include an interconnected phase extending through at least a portion of the bond matrix. The body can include a discontinuous phase including a plurality of discrete members. At least one of the discrete member can include a macroscopic pore. In another embodiment, the body can include a porosity of at least 15 vol % for a total volume of the body.

摘要： An abrasive article includes a blade body having an axis of rotation, and a peripheral edge comprising a plurality of blade segments with perimeter edges. Adjacent ones of the blade segments may be separated from each other by a slot that extends into the blade body at least partially in a radial direction with respect to the axis. At least one blade segment may include a plurality of apertures extending axially therethrough, comprising a perimeter edge aperture that intersects the perimeter edge, and at least two interior apertures are radially offset from and do not intersect the perimeter edge. An abrasive portion may include a bond material and abrasive particles, the abrasive portion overlies at least portions of the blade segments.

摘要： An abrasive segment can include an inner segment portion, an outer segment portion, and a central segment portion connected thereto. The inner segment portion can include an inner circumferential wall and an outer circumferential wall. Leading and trailing radial sidewalls can extend between the inner circumferential wall and the outer circumferential wall opposite each other. The outer segment portion can include an inner circumferential wall and an outer circumferential wall. Leading and trailing radial sidewalls can extend between the inner circumferential wall and the outer circumferential wall opposite each other. The central segment portion can include a leading radial sidewall and a trailing radial sidewall. The leading radial sidewall of the central segment portion can establish an acute angle, α, with respect to the outer circumferential wall of the inner segment portion and an obtuse angle, β, with respect the inner circumferential wall of the outer segment portion.

摘要： A process can include forming at least one precursor abrasive component on a core and infiltrating at least a portion of the precursor abrasive component. The precursor abrasive component can include a body including a metal bond matrix and abrasive particles. Infiltrating can be performed after forming the precursor abrasive component with an infiltrant material. The infiltrant material can include a metal element, an alloy or a combination thereof. In an embodiment, forming at least one precursor abrasive component can include simultaneously joining the precursor abrasive component to the core.
