摘要:
In the metal-cladding method disclosed a body of molten metal is located above the surface of the base metal to be clad. The metal is allowed to flow downwardly toward the surface through a restriction that shapes the metal striking the surface into an elongated narrow stream. The stream is about as long as the longest dimension of the surface being clad. The apparatus of the invention includes a mold having a crucible to hold the molten metal and a slot for restricting the flow of the molten metal into the mold cavity enclosing the surface being clad. The slot shapes the metal into an elongated, narrow stream that is about as long as the longest dimension of the surface being clad.
