摘要： An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.

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.

摘要： A core drill bit can include a first region and a second region. The first region can include abrasive particles in a first bond matrix, and the second region can include abrasive particles in a second bond matrix. The first region is connected to the second region. A composition of the first bond matrix can be different from a composition of the second matrix. In a particular embodiment, the first bond matric can include a Co-containing material.

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.
