<p>Provided is a dissolution-inhibiting covering member which exhibits not only excellent dissolution resistance but excellent resistance to repeated thermal shocks and thus has a prolonged life. Further, the surface layer of the dissolution-inhibiting covering member assumes such a special color that the degradation of the member can be grasped visually. Disclosed is a covering member to be applied to a base metal (such as iron) which tends to dissolve in molten aluminum when comes into contact therewith. The covering member is configured by laminating an undermost layer consisting of a metallic Cr film on the base metal, and then laminating, successively on the undermost layer, a layer (b) consisting of a CrN film, an interlayer, and a layer (a) consisting of a TiSiN film, said interlayer consisting of an alternating laminate of the layers (b) and (a).</p> |
