Electrolytic stripping solutions, which incorporate the novel use of oxoacids and/or oxoacid salts, and hydrogen peroxide, have been formulated for the rapid removal of electroless nickel from iron, steel, aluminum, and titanium alloys as well as other selected electrically conductive substrates. The formulations provide improved resistance to etching of the substrate and can be formulated to be free of chelates, chromates, nitrates, or concentrated acid solutions thereby increasing worker safety and reducing the cost of waste disposal of spent stripping solutions.
L'invention concerne des solutions de décapage électrolytique, contenant des oxacides et/ou des sels d'oxacides, et du péroxyde d'hydrogène. Lesdites solutions ont été formulées pour éliminer rapidement le dépôt autocatalytique de nickel d'alliages de fer, d'acier, d'aluminium, et de titane, ainsi que d'autres substrats conducteurs sélectionnés. Les formulations permettent d'accroître la résistance à l'attaque du substrat et peuvent être formulées sans chélate, ni chromate, nitrate, ou solution d'acide concentré, ce qui augmente la sécurité du travailleur et réduit les coûts d'élimination de déchets de solutions de décapage utilisées.
