Abstract
An electrodeposited wire tool has a core wire extending in a longitudinal direction, a plating layer provided on an outer peripheral surface of the core wire, superabrasive grains held by the plating layer and coating layers covering the outer peripheral surfaces of the superabrasive grains. The coating layers are constituted of electroless Ni—P platings. The coating layers are heat-treated, and the electroless Ni—P platings are partially or entirely crystallized.

1-21. (canceled)
An electrodeposited wire tool comprising:
- a magnetic linear body;
- and
- a plurality of metallized abrasive grains provided with metal coatings fixed to the outer peripheral surface of said magnetic linear body with a plating layer, wherein
- said metal coatings include electroless Ni—P platings having a P content of not less than 4 mass %, and said electroless Ni—P platings are at least partially crystallized.
A method of manufacturing an electrodeposited wire tool, comprising the steps of:
- heat-treating metallized abrasive grains coated with electroless Ni—P platings and at least partially crystallizing said electroless Ni—P platings;
- introducing said heat-treated metallized abrasive grains into a plating solution and making a magnetic linear body as a substrate adsorb said metallized abrasive grains in a dispersed state through magnetic force by magnetic induction and fixing said metallized abrasive grains by platings, wherein the content of P (phosphorus) in said electroless Ni—P platings is not less than 4 mass %.
