A FIXED ABRASIVE SAWING WIRE WITH NICKEL OXIDE INTERFACES BETWEEN NICKEL SUB-LAYERS

摘要

An inventive fixed abrasive sawing wire is described comprising a metallic core wire whereon abrasive particles are attached in an electroplated nickel layer. The electroplated nickel layer comprises two or more stacked sub-layers of which in between at least one pair of consecutive sub-layers an interface containing nickel oxide is present. A nickel oxide layer acts as a preferred fracture plane during sawing. As a result the abrasive particles are more easily uncovered during first use than in conventional fixed abrasive sawing wires of this type. This without leading to an increased overall wear of the wire. The inventive fixed abrasive sawing wire must therefore not be dressed prior to use. Furthermore, different exemplary methods are described to introduce a nickel oxide layer in between the nickel layers.
