摘要： The disclosure relates to a process for applying a multilayer protective coating to a substrate having an electrically conductive surface, comprising: (a) a first method of forming a silicate layer upon said electrically conductive surface, said first method comprising contacting at least a portion of said surface with a first medium comprising at least one silicate and having a basic pH and wherein said first medium is substantially free of chromates, to form a silicate layer, and (b) a second method of electrolytically applying a synthetic resin layer upon the surface of said silicate layer, said second method comprising contacting at least a portion of said surface of said silicate layer with a second medium comprising a resinous ingredient, applying an electric current to said second medium wherein said surface is employed as an electrode, to form a synthetic resin layer. The multilayer protective coating exhibits excellent corrosion and adhesion properties and is environmentally acceptable.
摘要翻译：本公开涉及一种将多层保护涂层施加到具有导电表面的基底上的方法，包括：（a）在所述导电表面上形成硅酸盐层的第一种方法，所述第一种方法包括使至少一部分所述表面具有包含至少一种硅酸盐并具有碱性pH的第一介质，并且其中所述第一介质基本上不含铬酸盐以形成硅酸盐层，以及（b）将合成树脂层电解施加到所述表面上的第二种方法的所述硅酸盐层，所述第二种方法包括使所述硅酸盐层的所述表面的至少一部分与包含树脂成分的第二介质接触，向所述第二介质施加电流，其中所述表面用作电极，以形成合成树脂层。多层保护涂层表现出优异的腐蚀和粘合性能，并且是环境可接受的。

摘要： The disclosure relates to a corrosion resistant article comprising a metal body and a protective coating applied on at least one surface of said metal body, said protective coating comprising: (a) a zinc layer comprising metallic zinc; (b) a silicate layer comprising at least one silicate; and (c) a lubricant layer comprising at least one lubricant such as, for example, polyethylene wax. In particular, the disclosure relates to a corrosion resistant bolt and/or nut having a protective coating for use in motor vehicles. The protective coating is substantially free of chromates and phosphates and, hence, environmentally acceptable. The article has an excellent coefficient of friction, temperature resistance and anti-corrosion properties.
摘要翻译：本公开涉及一种耐腐蚀制品，其包括施加在所述金属体的至少一个表面上的金属体和保护涂层，所述保护涂层包括：（a）包含金属锌的锌层; （b）含有至少一种硅酸盐的硅酸盐层; 和（c）包含至少一种润滑剂的润滑剂层，例如聚乙烯蜡。特别地，本公开涉及具有用于机动车辆的保护涂层的耐腐蚀螺栓和/或螺母。保护涂层基本上不含铬酸盐和磷酸盐，因此是环境可接受的。该制品具有优异的摩擦系数，耐温性和抗腐蚀性能。
