    • A method is disclosed for substantially uniformly coating an interior surface of a ferromagnetic tubular structure such as a ferromagnetic tube having a high aspect ratio. The method entails inducing a magnetic field of a given magnitude within the tubular structure. Further, a bias is applied at a given voltage to the tubular structure. Then, the interior surface of the tubular structure is exposed to a gaseous precursor material under conditions effective to convert a quantity of the gaseous precursor material to ionize gaseous precursor material. The given magnitude and voltage is such that it is effective to deposit the ionized the gaseous precursor material onto the interior surface and converts the ionized gaseous precursor material to a substantially uniform protective coating in the interior surface.
    • 公开了一种基本上均匀地涂覆铁磁管状结构的内表面的方法,例如具有高纵横比的铁磁管。 该方法需要在管状结构内引起给定量值的磁场。 此外,在给定电压下施加偏压到管状结构。 然后,管状结构的内表面在有效地将一定量的气态前体材料转化成电离气态前体材料的条件下暴露于气态前体材料。 给定的量值和电压使得将离子化的气态前体材料沉积到内表面上并将离子化的气态前体材料转化成内表面中基本均匀的保护涂层是有效的。
