“In-Rotating-Water Spinning” process is a useful technique which can obtain directly the continuous wires having circular cross-section by injecting molten metal jet into a rotating water layer, and further, which can make the crystal grains fine by rapid cooling solidification effect, and improve the mechanial properties.
We applied this method to try the direct wire making of hard and brittle, wear resistant Co-base alloys and the improvement of the mechanical strength.
According to the characteristics of the production method, (1) the apparatus for vertical type spinning in rotating liquid for 0.1-0.3mm diameter and (2) the apparatus for horizontal type spinning in rotating liquidfor 0.3-0.5mm diameter were used.
The kind of coolant is a very important factor, and in the case of this alloy, it was found that sodium carbonate aqueous solution was particularly effective.
The wires obtained by rapid cooling solidification were heattreated (at 1273-1373K for 1h), and the stabilization of the metastable phase and the refining of the crystalline structure were carried out, in this way, the wires having the aimed-at wear resistance and mechanical strength were obtained.
