The effects of rust inhibitors in brine on corrosion behaviors of copper and brass have been investigated by measurement of cathode and anode polarization curves and immersion test. As rust inhibitors, benzotriazole, sodium benzoate and sodium nitrite solutions were prepared. As a result, it was found that benzotriazole and sodium benzoate solutions have rust-inhibiting effect for both copper and brass. In contrast, sodium nitrite has poor rust-inhibiting effect on both copper and brass, compared to other rust inhibitors. © 2017 Japan Institute of Electronics Packaging.
