Abstract
An abrasive article including a substrate in the form of an elongated member having a core and a barrier layer in direct contact with an peripheral surface of the core. The barrier layer consists essentially of tin. A bonding layer is overlying the elongated substrate and abrasive particles are secured in the bonding layer.
Claims20
An abrasive article comprising:
- a substrate in the form of an elongated member comprising:
- a core;
- and
- a barrier layer in direct contact with a peripheral surface of the core, the barrier layer consisting essentially of tin;
- a bonding layer overlying the elongated substrate;
- and
- abrasive particles secured in the bonding layer, wherein at least about 50% of the abrasive particles are spaced away from an interface between the bonding layer and the barrier layer.
