Description
(1)アルミニウム線に、銀メッキ、銀クラッド被覆、金めっき、及び、金クラッド被覆から選択された被覆を施した音響用線材。
メッキ液内を走行する被メッキ線材を陽極として被メッキ線材表面の酸化物を除去する工程と、被メッキ線材を陰極として電気メッキする工程とを繰り返すことを特徴とする線材の電気メッキ方法。
この方法により陽極処理で酸化被膜を除去した後メッキ被膜を形成する操作を繰り返すので、酸化被膜を形成しやすい線材に対して連続的にメッキすることができる。
従来、アルミニウム線材は連続メッキできなかったが、この方法によりアルミニウム線の軽量である特長を生かし、更に通電性耐熱性、耐食性などの諸機能を向上せしめて電気機器分野、自動車関連の電気部品関係に使用及び活用を図ることができる。
置換・浸漬法を併用することにより、電気メッキ被膜とは異なる材質のメッキ被膜が形成されるので、酸化被膜も形成されにくく、本発明方法を容易におこなうことができる。
被メッキ線材表面の酸化物を最初に除去する工程は、被メッキ線材が最初の陰極電極体に対向する個所を走行して被メッキ線材が陽極となる時に行われ、2回目以降の被メッキ線材表面の酸化物を除去する工程は、被メッキ線材が前記陽極補助電極体内を走行して被メッキ線材が陽極となる時に行われる(1)に記載の方法。
陽極補助電極体を用いることにより、これが犠牲陽極となり、陽極処理時にメッキが溶離するのを防止することができる。具体的には、陽極処理時に、被メッキ線材の表面から、メッキ被膜が再び溶液の中に溶け出すので、その作用を極力防止し少くするために陽極補助電極体を陽極として用いる。例えば、被メッキ線材と陽極補助電極体とを電気的に接触せしめて設置し、溶出をこの陽極補助電極体が受け持つ。陽極補助電極体の形状を筒状、特に円筒状としてその中を線材が通過するような構造とすれば線材の表面積と円筒状との表面積の比率が非常に大きくなり、それだけ線材からの溶出が少なくなり線材へのメッキが完全なものとなる。
同じ材質とすることにより、陽極補助電極体からイオンがメッキ液中に流出し、被メッキ線材表面の電気メッキ被膜からメッキ被膜が流出するのを極力少なくすることができる。またメッキゾーンにおいて被メッキ線材表面に析出することによって失われる溶液中の金属イオンを補充することができる。
