    Abstract: A chromium-and-ferricyanide-free aqueous cleaner/deoxidizer for aluminum, the cleaner/deoxidizer having an etch rate on titanium that is low enough for practical use in processes where aluminum objects to be deoxidized are held on titanium racks or hangers during the process, combines boric acid, fluoborate anions, and an acid that is stronger than either of boric and fluoboric acids, usually also with an oxidizing agent such as hydrogen peroxide. Rates of etching of aluminum that are at least as much as 50 times the rates of etching of titanium under the same conditions can be achieved, and the deoxidizing of the aluminum is satisfactory for achieving corrosion resistance after subsequent conversion coating of the deoxidized aluminum surface.

    Abstract translation: 用于铝的不含铬和铁氰化物的含水清洁剂/脱氧剂，该清洁剂/脱氧剂在钛上的蚀刻速率足够低以供实际应用，其中在待处理的铝物体上待处理的铝物品被保持在钛架或吊架上 将硼酸，氟硼酸根阴离子和比硼酸和氟硼酸强的酸，通常也与氧化剂如过氧化氢结合。 在相同的条件下，可以实现至少为蚀刻钛的50倍的铝的蚀刻速率，并且铝的脱氧对于实现后续的脱氧铝表面的转化涂覆后的耐腐蚀性是令人满意的。

    Abstract: Anodized aluminum surfaces are advantageously sealed by an energy- and time-saving two step process, in which the first step is contact at not more than 75° C. with a solution containing lithium and fluoride ions and, optionally, surfactant. The second necessary step is treatment with hot water or steam, which may be completed in considerably less time when only hot water or steam is used for sealing. Conventional smut inhibitors and/or neutral buffers as used in hot water for single step sealing may advantageously be included in the second step of this process. 100-1000 ppm concentrations of nickel and/or cobalt ions in the treatment liquid for the second treatment step, if environmentally tolerable, make it possible to complete this step in as little as 10 minutes at a temperature as low as 88° C.

    Abstract: Seal coating compositions and methods of applying them to metallic surfaces, particularly aluminum or alloys thereof, bearing a previously formed protective coating, particularly a conversion coating, such as a chromate or phosphate coating or a chrome-free metal oxide conversion coating, or a coating formed by anodization, provide improved corrosion resistance beyond that provided by the previously formed protective coating. The seal coating compositions preferably contain at least one of benzotriazole, nickel and or cobalt cations and borates, or aminated polymers of vinyl styrene.

    Abstract: 2106953 9218661 PCTABS00017 Seal coating compositions and method of applying same, to metallic surfaces, particularly aluminum or alloys thereof, containing a previously formed protective coating on the metal surface, to provide for improved corrosion resistance beyond that provided by the previously formed protective coating. Aqueous solutions of the seal coating components are applied to the metal surface containing the previously formed coating which is subsequently rinsed and dried to provide metal articles having improved resistance to corrosion.
