- 코오팅중의 접착부분을 제거하지 않고서도 이물질을 제거하여 전극표면을 청결히하고 오래된 코오팅위에 이 코오팅과 조성이 유사한 새로운 전기촉매성 코오팅을 여러겹 형성시킬때 각층마다 건조와 가열처리를 함에 있어서, 청결화 된 전극 표면에 최소한 한가지의 분해성 백금족금속을 화합물의 용액으로 1겹 이상 코오팅하고 각겹마다 용액이 오래된 코오팅속을 침투해 들어가게 하며 각 겹을 건조한후 가열처리하여 백금족 금속 또는 그 산화물로 오래된 코오팅을 강화시켜 주므로서 새로운 전기촉매성 코오팅을 실시하기 전과 청결히 한 후 전극 표면을 활성화함을 특징으로 하는 최소한 한가지의 기타 금속 산화물과 함께 밸브 금속 산화물 최소한 한가지와 백금족 금속 산화물 최소한 한가지를 함유하는 전도성의 전기촉매성 코오팅과 밸브 금속 베이스가 있는 이전에 사용된 치수가 안정한 전극을 재코오팅하는 방법.
- 청구범위 제1항에 있어서 오래된 코오팅중에 있는 밸브 금속을 공격하여 가열단계에서 이것을 백금족 금속 화합물과 혼합하여 이 화합물을 밸브금속 및 백금족 금속 또는 그 산화물로 전환시키는 밸브금속의 이온으로 전환시키는 약제를 용액중에 함유토록 하는 방법.
- 청구범위 제2항에 있어서 산화성 분위기에서 가열처리하므로서 용액에서 나오는 백금족 금속이 오래된 코오팅에서 나오는 밸브금속 이온과 더불어 혼합된 백금족 밸브금속 산화물을 형성하도록 하는 방법.
- 청구범위 제2항 또는 제3항에 있어서 새로운 코오팅으로 재코오팅되는 밸브금속의 노출면을 가진 재코오팅될 전극을 청결히 한 후 가열단계도중 용액중의 약제가 밸브금속을 공격하며 베이스의 노출부분에서 나오는 밸브금속을 밸브금속 화합물로 전환시키는 이온으로 전환시켜 노출부분에 백금족 금속이나 그산화물을 결합하는 밸브금속 화합물의 장벽층을 형성하도록 하는 방법.

- 청구범위 제8항에 있어서, 백금족 금속화합물 5-15g/ℓ(금속으로서)을 활성화용액 중에 함유시키는 방법.
- 청구범위 제8항 또는 9항에 있어서 활성화 용액보다 금속중에서 더욱 농축되며 백금족 금속과 기타 금속 화합물(금속으로서)을 35-150g/ℓ함유하는 용액으로부터 새로운 전기 촉매성 코오팅을 형성시키는 방법.
- 앞서 나온 청구범위들중 어느 한가지에 있어서 활성화 처리에 의해 백금족 금속 및 그 산화물(금속으로서) 0.1-1g/㎡으로 오래된 코오팅을 강화시키는 방법.
- 앞서 나온 청구범위들중 어느 한가지에 있어서 활성화 용액을 처리하기 전후에 350-650℃의 온도에서 비산화성 분위기에서 전극을 가열처리하는 단계를 활성화 처리공정중에 포함시키는 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
