摘要： In a tank of aluminizing electroplating cells which may contain racks for articles, operated with aprotic oxygen-free and water-free organo-aluminum electrolytes, a lining of individual segments coated with resistant materials (enamel or electrolyte-resistant plastics) is provided as an electrically insulating protective device. The outer edges of the side baffles, coated all around, are bent round toward the outside and are held together by connecting straps which are bent round toward the inside. The individual bottom segments coated all around lie on top of each other overlapping in roof tile fashion. The protective device may also include a similarly insulated band arranged all around the cell.

摘要： Aluminum materials and aluminized parts are oxidatively anodized at a bath temperature of 0.degree. to 15.degree. C. and preferably, 0.degree. to 10.degree. C. to produce an anodized layer of aluminum oxide more than 4 microns thick, which is hard, abrasion-proof and can be stained. The anodizing is bath used while conducting air free of or low in carbon dioxide through the bath. It is free of substances which limit the oxide layer to maximally a thickness of about 1 micron (forming layer) and contains 10 to 500 g trisodium phosphate or tripotassium phosphate per liter. In partially aluminized parts, no destruction of the base material occurs during the aluminizing.

The anodizing is carried out at a pH value of less than 1 with a current density of 0.5 to 3 A/dm.sup.2 at 0.degree. to 30.degree. C. The method can be used with partially aluminized parts without destroying the base material.

摘要： In known devices for galvanic deposition of metal from electrolyte onto goods, wherein a galvanic drum contains electrolyte within a tank, the removal of metal undesirably deposited on the cathode contact or the replacement of used up cathode contacts from the drum has been very time-consuming and presented a contamination problem since these operations required opening of the galvanizing tank. The invention concerns a contact replacement or cleaning arrangement which can be done simply and does not necessitate undue exposure to ambient of the tank, since the used contact is removed within the tank and replaced by opening only a narrow passage through a galvanic drum axle.

摘要： In order to avoid smoke formation within the cover hood for the plating tank in an assembly for the electro-deposit of aluminum and contamination of charging and discharge liquid locks leading to and from the cover hood, a liquid spray chamber and a cooled condensing zone are disposed beneath a slotted cover plate leading to the interior space of the cover hood and the open ends of the individual electrolyte cell. The substrate goods and goods carriers are sprayed and cooled leaving the electro-deposit cells prior to being passed back into the interior space of the cover hood.

摘要： An improved galvanizing device for the galvanic precipitation of aluminum from an anhydrous, aprotic, and oxygen-free aluminum-organic electrolyte is provided. The known device having an annularly shaped galvanizing trough, which is sealed from the atmosphere and which utilizes a centrally located, rotatable support mechanism which guides the goods carriers through the electrolyte in a circular, rotating manner, and also furnishes the goods carriers with an electrical contact, is herein provided with separate charging and discharging locks attached to the galvanizing trough. Each of the locks is provided with a U-shaped fluid lock to maintain the gaseous seal and an endless chain conveyor to transport the goods carriers to and from the galvanizing trough. Additionally, the anode plates which are located in the electrolyte trough are provided with a transport rod to permit their removal and replacement in a manner similar to that utilized with the goods carriers.

摘要： Articles made of ferrous, non-ferrous and light metals and alloys thereof, e.g., aluminum, beryllium, magnesium, molybdenum, steel, tantalum, titanium, tungsten, vanadium and zinc and their alloys, are pretreated before coating and surface finishing in an anhydrous, inert, aprotic liquid, and subsequently electroplated with aluminum, cadmium, indium or zinc in an aprotic organo-metal electrolyte essentially free of molecular oxygen and water and, optionally, additionally finished by anodizing, chemical oxidation or diffusion. The pretreatment may be by erosion with finely-divided abrasive particles suspended in such liquid and impinged upon the surface of the article by hydraulic jetting, or with an aprotic liquid by the liquid-drop erosion method. Alternatively, the pretreatment may be by electrolytic action in a circuit where the article serves as the anode and is immersed in an anhydrous, aprotic electrolyte. Articles so pretreated and electroplated are thereafter more readily surface-finished or mechanically shaped.
摘要翻译： 由无色金属，有色金属和轻金属及其合金制成的制品，例如铝，铍，镁，钼，钢，钽，钛，钨，钒和锌及其合金，在无水涂层和表面处理前进行预处理 惰性的非质子液体，随后在基本上不含分子氧和水的非质子有机金属电解质中用铝，镉，铟或锌电镀，并且任选地通过阳极氧化，化学氧化或扩散完成。 预处理可能是通过用悬浮在这种液体中的细碎磨料颗粒进行腐蚀，并通过液压喷射冲击在物品的表面上，或者通过液滴腐蚀方法与非质子液体碰撞。 或者，预处理可以在电路中通过电解作用，其中制品用作阳极并浸没在无水非质子电解质中。 因此，如此预处理和电镀的制品更容易进行表面处理或机械成型。
