    • The invention relates to metal foam bodies having an open-porous structure as well as a method for producing thereof wherein according to the set task such metal foam bodies are to be provided which achieve an increased oxidation resistance and/or an increased corrosion resistance. With the metal foam bodies having an open-porous structure according to the invention, for such metal foam bodies within the webs of the open-porous structure there are channel shaped cavities formed as being determined by the production. At the same time, the webs and cavities will be provided with a metallic protective layer made of a material differing from the metallic starting material of the foam body or the channel shaped cavities will be filled with this material. For this, an adequate metal powder or an alloy component being included in the powder will be used which becomes liquid and forms a liquid phase respectively during thermal treatment below a temperature at which the metal of the base foam body is melting. Due to the capillary action wetting the surfaces of channel shaped cavities within the webs can be achieved such that after cooling down a metallic protective layer is forming or the channel shaped cavities are filled.
    • 本发明涉及具有开孔结构的金属泡沫体及其制造方法,其中根据设定的任务,将提供这样的金属泡沫体,其实现增加的抗氧化性和/或增加的耐腐蚀性。 对于根据本发明的具有开孔结构的金属泡沫体,对于在开孔结构的腹板内的这种金属泡沫体,存在通过生产确定的通道形空腔。 同时,纤维网和空腔将设置有由与泡沫体的金属起始材料不同的材料制成的金属保护层,或者通道形状的空腔将被该材料填充。 为此,将使用在粉末中包含的足够的金属粉末或合金成分,它们在基体泡沫体的金属熔化的温度以下的热处理期间分别成为液体并形成液相。 由于毛细作用润湿,纤维网内的通道形状空腔的表面可以实现,使得在冷却之后,形成金属保护层或填充通道形状的空腔。
