摘要： A method for producing a structured hard chromium layer, during which chromium from an electrolyte is deposited onto a workpiece, which contains: a) a Cr(VI) compound in a quantity corresponding to between 50 and 300 g/l of chromic anhydride; b) 0.5 g/l to 10 g/l sulfuric acid, and; c) 5 g/l to 15 g/l aliphatic sulfonic acid having 1 to 6 carbon atoms. The electrolyte comprises substantially no compounds from the group consisting of ammonium molybdate, alkaline molybdate, alkaline earth molybdate, ammonium vanadate, alkaline vanadate and alkaline earth vanadate, ammonium zirconate, alkaline zirconate and alkaline earth zirconate, and is processed with a cathodic efficiency of 12% or less. A method for producing a coating, to a structured hard chromium layer, a coating and an electrolyte.

摘要： The invention relates to a method for applying electro-deposited metal coatings (3) upon aluminium or aluminium alloy components (1). According to said method, the surface (4) of the component is cleaned in an appropriate solution, in particular a solution of oils, fats, emulsions, pigments, etc. Said surface (4 ) is then etched in an appropriate solution, such that a certain quantity of material or near-surface alloy constituents is dissolved. After cleaning and dissolution, water rinsing is carried out. Immediately after the dissolution of the near-surface regions, the surface (4) of said component (1) is activated in a solution, containing iron ions, with a sulphate base by the anodic coupling of said component (1). The functional layer (3) is then applied by the cathodic coupling of said component (1), without intermediate rinsing, in the same electrolyte or in a similar or equivalent electrolyte, said functional layer (3) being made of iron (5).
摘要翻译：本发明涉及一种将电沉积金属涂层（3）涂覆在铝或铝合金部件（1）上的方法。根据所述方法，将组分的表面（4）以合适的溶液，特别是油，脂肪，乳液，颜料等的溶液进行清洁。然后将所述表面（4）在合适的溶液中蚀刻，使得一定量的材料或近表面合金成分被溶解。清洗和溶解后，进行水洗。在近表面区域溶解之后，通过所述组分（1）的阳极耦合，所述组分（1）的表面（4）立即在含有铁离子的溶液中与硫酸根碱一起活化。然后，功能层（3）通过所述组分（1）的阴极耦合而在相同的电解质或类似或等同的电解质中进行中间漂洗，所述功能层（3）由铁（5）制成。
