摘要： The present invention describes a cost-saving and environmentally conserving process for the electrochemical polishing of steel, in particular of low-alloy steels. The workpieces are rinsed after electropolishing in an arid phosphoric acid-sulfuric acid-bath in a first rinsing step with a phosphoric acid-containing solution, whereby a chemical attack on the freshly polished surfaces is avoided without the use of environmentally harmful and unhealthy inhibitors such as chromates. By recycling of the acids and the rinsing solution, these acids and solutions can be regenerated, whereby the process can be designed effluent-free.

摘要： The present invention relates to a process for improving the heat and corrosion resistance of stainless steel by means of a novel passivation process. This process comprises a chemical treatment with an aqueous solution comprising a complexing agent combination of at least one oxidant, a subsequent rinsing and a subsequent treatment at elevated temperature in an oxygen-containing atmosphere. The stainless steel surfaces obtained according to the invention have a homogeneous passive layer having increased chemical resistance and resistance to thermal discoloration.

摘要： The present invention relates to a method of electrochemical polishing of surfaces of cobalt or cobalt alloys. It employs an electrolyte comprising glycolic acid and at least one alkane-sulfonic acid with an alkyl residue that has 1 to 3 carbon atoms. This electrolyte is also one aspect of the present invention. In one embodiment, at least one alkane-sulfonic acid comprises methane-sulfonic acid. The electrolyte and the method using this electrolyte are suitable in particular for surfaces of cobalt or cobalt alloys, including cobalt-chromium alloys such as stellite.
