    • The invented method of cladding a metal component includes creating a frit mixture in a defined ratio; wetting the mixture by adding a wetting agent in a defined volume; agitating the wetted mixture; applying the agitated mixture to a metal component by one or more processes; de-wetting the metal component having the applied mixture by gradually heating the same to a temperature from approximately 250 degrees Fahrenheit (°F) up to a high of approximately 450°F; and, fusing the de- wetted metal component at a temperature of no more than 125% of a defined withstand temperature for the clad metal component. Invented compositions can include one or more of liquid and/or colloidal sodium, potassium and/or lithium silicate, clay and/or clays, a compound of hollow micro-spheres (e.g. naturally occurring and nearly ubiquitous perlite and/or a synthetic hollow micro-sphere equivalent) and/or alumina or one or more flexible or malleable or resiliently deformable, impact-resistant materials such as plastomers, elastomers and/or other plastic, rubber, plastic-like or rubber-like materials; a wetting agent consisting of one or more of water or water and ethanol for fast drying under proper safety and venting conditions; and one or more surfactants and/or dispersants. A system and method for using the compositions and additives are also disclosed. An optional powder clad application method is included in the embodiment of the invention which method eliminates the de-wetting station(s) but makes it possible to add impact-resistant clad material for lower-temperature, higher-impact applications.
    • 本发明的包覆金属部件的方法包括以确定的比例产生熔块混合物; 通过加入限定体积的润湿剂来润湿混合物; 搅动湿润的混合物; 通过一个或多个过程将搅动的混合物施加到金属部件上; 通过将具有所施加的混合物的金属组分逐渐加热至约250华氏度(℉)至高达约450°F的温度来去湿该金属组分; 以及在不超过金属包覆部件的规定耐受温度的125%的温度下熔化脱湿的金属部件。 本发明的组合物可以包括一种或多种液体和/或胶体钠,钾和/或硅酸锂,粘土和/或粘土,空心微球的化合物(例如天然存在且几乎普遍存在的珍珠岩和/或合成中空微型 等效)和/或氧化铝或一种或多种柔性或可延展或可弹性变形的耐冲击材料,例如塑性体,弹性体和/或其它塑料,橡胶,塑料样或橡胶类材料; 由一种或多种水或水和乙醇组成的润湿剂,用于在适当的安全和排气条件下快速干燥; 和一种或多种表面活性剂和/或分散剂。 还公开了使用该组合物和添加剂的系统和方法。 在本发明的实施例中包括一种可选的粉末涂层涂覆方法,该方法消除了一个或多个去湿站,但是可以添加用于较低温度,较高冲击应用的抗冲击包覆材料。
