  Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  以锰为基础的缓蚀颜料含有三价或四价锰/价稳定剂复合物。一种无机或有机材料可用于稳定三价或四价锰离子，从而形成一种可少量溶解、溶解度低或不溶于水的化合物，具体取决于预期用途。选择特定的稳定剂是为了控制三价锰或四价锰在遇水时的释放率，并调整粉末在所选粘合剂体系中用作颜料时的相容性。稳定剂还可以改变成型粉末的加工和处理特性。锰/价稳定剂组合的选择是基于锰配位化学的基本原理。文中介绍了许多锰价稳定剂组合，其性能与传统的六价铬或四价铅体系相当。需要强调的是，提供本摘要是为了符合要求提供摘要的规则，以便检索者或其他读者快速确定技术公开的主题。提交本摘要的前提是，本摘要不用于解释或限制权利要求的范围或含义。

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.

  一种缓蚀颜料，由稀土元素和价态稳定剂结合形成稀土/价态稳定剂复合物。稀土元素选自铈、铽、镨或它们的组合，至少有一种稀土元素处于四价氧化态。使用无机或有机材料来稳定四价稀土离子，以形成稀溶于水的化合物。选择特定的稳定剂是为了控制四价铈、铽或镨在遇水时的释放率，并调整粉末在所选粘合剂体系中用作颜料时的相容性。稳定剂还可以改变成型粉末的加工和处理特性。本文介绍了许多稀土-价稳定剂组合，其性能可与传统的六价铬体系媲美。

  Rinsing or sealing solutions comprising a rare earth element and a valence stabilizer for barrier films. The treated films contain a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, praseodymium, terbium, or combinations thereof, and at least one rare earth element is in the tetravalent oxidation state. The rinsing or sealing solution may also contain an optional preparative or solubility control agent. The oxidized rare earth element is present in the coating in a “sparingly soluble” form. The valence stabilizers can be either inorganic or organic in nature. A number of rare earth/valence stabilizer combinations that match the performance of conventional hexavalent chromium systems are presented.
