TI ALLOY FOR POSITIVE ELECTRODE FOR ELECTROCOAGULATION PRINTING, POSITIVE ELECTRODE AND PRINTING APPARATUS

摘要

A Ti alloy for a positive electrode for electrocoagulation printing contains, as a weight percentage, 28.0 to 35.0% of Al, 0.1% or less of C, 0.05% or less of N, 0.3% or less of O, and Ti. The Ti alloy may further contain one or more elements selected from the group consisting of 0.5 to 15.0% of Nb, 0.5 to 15.0% of Ta, 0.1 to 1.0% of Hf, 0.1 to 1.0% of Zr, 1.0 to 6.0% of W, 1.0 to 6.0% of Mo, 0.5 to 6.0% of Cr, 0.5 to 6.0% of Mn, 0.5 to 6.0% of V, 0.1 to 1.0% of Si, and 0.005 to 0.10% of B, by weight. A positive electrode for electrocoagulation printing has a surface composed of a Ti alloy containing A1.
