摘要： Fluoride-containing scale can be removed from metal surfaces such as titanium, titanium alloys, nickel alloys, and stainless steel by contacting the metal surfaces with an aqueous salt solution of an inorganic acid, including its hydrates. The cationic portion of the salt can be aluminum, iron and mixtures thereof. The anionic portion of the salt can be a chloride, a nitrate, a sulfate, and mixtures thereof. The contracting occurs in the absence of the addition of an acid, such as hydrochloric, nitric, or sulfuric acid. The presence of the aqueous salt solution with the dissolved fluoride scale does not accelerate or increase the normal rate of metal corrosion that can occur in the absence of the aqueous salt solution or any acidic cleaning agent.
摘要翻译：通过使金属表面与无机酸（包括其水合物）的盐水溶液接触，可以从金属表面如钛，钛合金，镍合金和不锈钢中除去含氟化合物的垢。盐的阳离子部分可以是铝，铁及其混合物。盐的阴离子部分可以是氯化物，硝酸盐，硫酸盐及其混合物。在没有加入酸如盐酸，硝酸或硫酸的情况下发生收缩。溶解的氟化物垢的盐水溶液的存在不会加速或增加在不存在盐水溶液或任何酸性清洁剂的情况下可能发生的金属腐蚀的正常速率。

摘要： This invention describes a series of Fe-Mn-Al-C based corrosion resistance alloys. It also describes how to obtain such alloys which have good corrosion resistance in many environments as compared to conventional stainless steel such as 304 and 430. The correlation of chemical composition among the manganese, aluminum, carbon and other minor elements is discussed. According to more advanced understanding the Fe-Mn-Al-C based alloys have to be surface treated and/or pickled, passivated by the methods included described. After the surface treatment, the final product will have a depleted manganese and/or higher chromium content on the alloy surface and will have better corrosion resistance than the conventional Fe-Mn-Al-C and Fe-Mn-Al-C-Cr based alloys. In addition, the manufacture and fabrication processes for the present designed Fe-Mn-Al-C based alloys also include melting, mixing, ingot casting, hot working, cold working, heat treatment and surface treatment.
摘要翻译：本发明描述了一系列基于Fe-Mn-Al-C的耐腐蚀合金。它还描述了如何获得与常规不锈钢（如304和430）相比在许多环境中具有良好耐腐蚀性的合金。讨论了锰，铝，碳和其他次要元素之间化学成分的相关性。根据更先进的理解，Fe-Mn-Al-C基合金必须通过所述方法进行表面处理和/或酸洗，钝化。在表面处理后，最终产品在合金表面上的锰含量和/或更高的铬含量将比常规的Fe-Mn-Al-C和Fe-Mn-Al-C-Cr基具有更好的耐腐蚀性合金。此外，本设计的Fe-Mn-Al-C基合金的制造和制造方法还包括熔融，混合，铸锭，热加工，冷加工，热处理和表面处理。

摘要： A method for pickling iron or steel objects before a subsequent surface treatment or mechanical processing. The objects (11) are transported into a pickling bath (10) having a temperature above 25 C and containing a solution of ferrous chloride and a low proportion of free hydrochloric acid. The pickling bath is continuously regenerated in a circulation system with electrolytic cells (14). These are preferably electrically connected in series and in parallel with the flow of the pickling bath, in order to deposit iron on the cathode (19) and recover free acid.
