    (A) In the prodn. of an erosion electrode, esp. a wire electrode for spark erosion cutting of conductive materials, comprising a metal (alloy) core and one or more sheath layers of low evapn. temp. alloy (e.g. Zn-Cu), the novelty is that an active sheath layer of the alloy with low evapn. temp. and limited cold formability is produced by annealing the wire electrode to obtain an alloy layer with decreasing content of the low evapn. temp. metal extending from the outer rim of the sheath layer to the core and then cooling to fix this diffusion state. Also claimed is an erosion electrode, esp. a wire electrode in which the core consists of a homogeneous alloy and the sheath layer consists of an alloy with an alloy constituent concn. decreasing inwardly towards the core.

    专利说明:

    The invention relates to the field of electrophysical and electrochemical processing methods, and in particular to methods for the manufacture of electrode-wire.
    The aim of the invention is to reduce wear during EDM cutting by heat treatment of the electrode-wire.
    The method is carried out as follows.
    A layer of zinc, cadmium or antimony is applied to the copper wire or copper alloy wire. The resulting wire is subjected to heat treatment in a tubular furnace in an atmosphere of nitrogen, argon or hydrogen at 700-850 ° C for 0.096-0.3 minutes Then the wire is cooled in a cooling zone, equipped with a water bath, to 30-80 ° C for 0.02-0.2 minutes. Received
    the wire can be calibrated by pulling.
    EXAMPLE 1 Electrolytic copper with a diameter of 0.3 mm, containing more than 99.9% by weight of copper and 0.01% of oxygen, is coated with a 5 micron thick zinc sheath. The wire thus obtained is heat treated at 750 ° C for 0.1 min in a tubular furnace 5.8 m long equipped with an electric heating device. A tubular cooling zone is connected to the furnace, equipped with a water bath, where the heat-treated body is cooled for 0.045 minutes (45% of the heat treatment time) to 60 ° C. Both heat treatment and subsequent cooling are carried out in a nitrogen atmosphere.
    The wire prepared in this way is used as an electrode for EDM cutting products at a productivity of 250. In this case, during the test period, the wear of the electrode in the working area is 24 microns. In the case of using an electrode-wire prepared by a prototype of the same materials as the electrode of example 1, the wear is 75 microns.
    The table shows additional examples 2-9 implementation of the method,
    In Example 3, cooling is carried out with water supplied using nozzles, and in Examples 7-9, air. In addition, in Examples 5, 6, after cooling, another calibration is carried out by drawing to a final diameter of 0.3 and 0.4 mm, respectively.
    Electrode wear according to examples 2-9 is 16-30 microns.
