METHOD TO PRODUCE A FIXED ABRASIVE SAW WIRE WITH A METAL ALLOY FIXATION LAYER AND THE WIRE RESULTING THEREFROM

摘要

A method is described to produce a fixed abrasive saw wire (104) by electrolytic deposition of abrasive particles pre-coated with a first metal on an elongated substrate wire (104, 202). The method is specific in that in the initial fixation bath (110) of the abrasive particles activating metal ions are added differing from the first metal. The activating metal ions deposit together with first metal ions in a fixation layer on the metallic substrate wire (104, 202) and enhance the activity of abrasive particles that are only partly coated. Thereafter a bonding layer is deposited from a deposition bath (108) that is free of added metal bonding layers. The resulting wire (104) has more than 70% of all activating metal present close to the metallic substrate wire (104, 202) within a width of 30% of the total thickness of the fixation and bonding layer
