摘要： @ This disclosure is concerned with a method for treating a stainless steel surface by high temperature oxidation. The surface of a stainless steel article is cleaned. Ti0 2 and Si0 2 are mixed in microparticles to form a coating agent, and water is added to the mixture to make a slip. The slip is coated on the steel surface to form a coating having a uniform thickness. The coating is dried and the article is subjected to a heat-treatment to form an oxide film. This treatment is performed in an oxidizing atmosphere for a time and a temperature suitable for the color tone to be produced. A desirable temperature for the heat-treatment is between 350°C to 700°C. When a coating agent is used, it is later removed by washing, etc. after cooling the article.
Further, when less dissolution of iron from the stainless steel surface is required, a decolorization treatment is applied; that is, the colored oxide film is removed from the surface by dissolution using an acid or an electrolytic treatment.摘要翻译： 本公开涉及通过高温氧化处理不锈钢表面的方法。 清洁不锈钢制品的表面。 将TiO 2和SiO 2在微粒中混合以形成涂布剂，并向混合物中加入水以形成滑移。 将滑移涂覆在钢表面上以形成具有均匀厚度的涂层。 将涂层干燥并对制品进行热处理以形成氧化膜。 该处理在氧化气氛中进行一段时间和适于生成色调的温度。 用于热处理的理想温度为350℃至700℃。当使用涂布剂时，在冷却物品之后，随后通过洗涤等除去。 此外，当需要不锈钢表面的铁溶解较少时，进行脱色处理; 也就是说，通过使用酸或电解处理的溶解将有色氧化膜从表面除去。

摘要： A cell culture method proliferates microorganisms, particularly fungi such as molds, actinomycetes, animal cells, plant cells and so on to produce useful substances such as antibiotics, enzymes, proteins, polysaccharides, physiological active substances, and animal and plant hormones. Porous material including the medium and cells to be proliferated is moved, whereby air is supplied to the surface of the porous material.

摘要： This disclosure relates to electrolytic decontamination of radioactively contaminated objects such as equipment or parts. The objects to be decontaminated are divided into two types: First, wastes resulting from dismantlement of radioactively contaminated equipment and parts, and second, equipment, vessels, pipes and tools that are to be reused. The electrolyte used for decontamination of the first type may be an inorganic acid aqueous solution of relatively low concentration that is inexpensive and rapid in polishing. A suitable inorganic acid is sulfuric acid that does not generate harmful gases in the process of electrolysis. The concentration of the sulfuric acid should be high to achieve polishing efficiency. About 5 Vol.% is the most suitable for uniform polishing and disposal of waste electrolyte. An electrolyte of this concentration is effective in macroscopic polishing but not in microscopic polishing (mirror finish), however. Therefore, an electrolyte for decontamination of the second type that requires microscopic polishing must be a high concentration acid solution, preferably 70% or higher phosphoric acid content. The electrolyte is reproduced by an electrodeposition process in diaphragm electrolysis.
