Снижение токсичности электролитов для электрополирования прецизионных сплавов и сталей

Abstract

The anodic behavior of stainless steels, molybdenum and molybdenum-noble alloys in electrolytes based on sulfuric phosphoric acids with additives of various low-toxic oxidants and biological soft surfactants that do not pollute the environment has been studied. It has been shown that the introduction of polishing for stainless steels of molybdenum and tungsten heteropolyacids into stainless electrolytes, and for precutious molybdenum alloys with rhenium of carboxymethylcellulose and a wetting agent of NB leads to an expansion of the range of working current densities at which the microrelief of the polished surface is effectively smoothed and the quality of the polished surface is improved.
