  • Process of forming an abrasive article
    Patent number: 10730164
    Abstract: 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.
