摘要： The invention relates to an electrochemical deposition system for a chemical and/or electrolytic surface treatment of a substrate, a module for chemical and/or electrolytic surface treatment of a substrate in a process fluid, a use of the electrochemical deposition system or the module for chemical and/or electrolytic surface treatment for a metal deposition application and a manufacturing method for an electrochemical deposition system for a chemical and/or electrolytic surface treatment of a substrate.
The electrochemical deposition system comprises an anode, an anode enclosure, and a single electrolyte. The anode enclosure extends at least partially around the anode. The anode enclosure comprises a membrane. The anode and the anode enclosure are arranged in the single electrolyte. The single electrolyte is the only electrolyte of the electrochemical deposition system.-

摘要： What is provided is stannous oxide having an α-ray emission amount of 0.002 cph/cm 2 or less after heating in an atmosphere at 100°C for 6 hours. Tin containing lead as an impurity is dissolved in a sulfuric acid aqueous solution to prepare a tin sulfate aqueous solution, and lead sulfate is precipitated in the aqueous solution and removed. While stirring the tin sulfate aqueous solution from which lead sulfate has been removed, a lead nitrate aqueous solution containing lead having an α-ray emission amount of 10 cph/cm 2 or less is added to cause lead sulfate to be precipitated in the tin sulfate aqueous solution, and simultaneously the tin sulfate aqueous solution is circulated while removing the lead sulfate from the aqueous solution. A neutralizing agent is added to the tin sulfate aqueous solution to collect stannous oxide.

摘要： This application relates to a method for forming an enclosure for a portable electronic device. The enclosure includes a metal substrate having a first b* value. The method includes forming an anodized layer that overlays and is formed from the metal substrate, wherein the anodized layer has a second b* value that is no greater than 0.3 of the first b* value and no less than 0.3 less than the first *b value.

摘要： Es wird ein Verfahren zur Erzeugung einer thermisch relaxierten Oxidschicht auf einer Oberfläche eines Materials mittels eines elektrolytischen Oxidationsprozesses, wobei die Energie, die für den Oxidationsprozess benötigt wird, pulsweise zugeführt wird, und eine mittels dieses Verfahrens hergestellte Oxidschicht vorgeschlagen, wobei ein Energiepuls aus drei Phasen, nämlich Anfangsphase, Mittelphase und Endphase, besteht und die Energiezuführung zumindest in der Mittelphase entladungsfrei erfolgt.
