ABRASIVE TOOLS WITH CONTINUOUS METAL PHASE FOR ATTACHMENT OF ABRASIVE COMPONENT TO BEARING ELEMENT Russian patent published in 2012 - IPC B24D3/04 

FIELD: machine building.

SUBSTANCE: abrasive product contains bearing element, abrasive component and attachment area between abrasive component and bearing element. Abrasive component contains abrasive particles secured with metal matrix. Abrasive component contains also net of interconnected pores filled with infiltrant greatly. Infiltrant composition is that of infiltrant containing at least one metal element. Attachment area contains binding metal with composition of binding metal containing at least one metal element. Attachment area is the area different from bearing element and being a separate phase of bearing element. Differential of elements weight percent is an absolute value of differential of weight content of each element containing in composition of binding metal relative to composition of infiltrant. Differential of elements weight percent between composition of binding metal and composition of infiltrant does not exceed 20 weight percent.

EFFECT: improving bonding between abrasive component and bearing element.
