Abstract
A method for manufacturing a clad component in which a cladding workpiece having a section comprising a first metal onto which a number of metal beads are rigidly bonded is inserted into a mold. A molten second metal is poured into the mold, where it flows about and covers the beads and is then permitted to cool. This process forms an article made of the second metal, which is mechanically interlocked to the beads, clad by the first metal. Typically the first metal is a high-melting point strong metal, such as steel, and the second metal is a lower-melting point, weaker, but lighter metal, such as aluminum.
Claims26
A method for manufacturing a clad component comprising:
- (a) providing a cladding workpiece having a section comprising a first metal, said section having an external surface area;
- (b) providing a multiplicity of metal beads separate from the cladding workpiece, each metal bead having a cross-section of at least 0.5 mm;
- (c) bonding the multiplicity of metal beads rigidly to at least a portion of said external surface area:
- (d) inserting said workpiece into a mold;
- (e) providing a molten second metal;
- and
- (f) pouring said molten second metal into said mold so that it flows about and covers said beads and permitting said molten second metal to cool, thereby forming an article made of said second metal, which is mechanically interlocked to said beads, clad by said first metal.
A method for manufacturing a clad component comprising:
- (a) forming a cladding workpiece by:
- (i) providing a preliminary workpiece made of a first metal and having a preliminary workpiece external surface area,
- (ii) providing a binder,
- (iii) providing a set of metal beads,
- (iv) using said binder to adhere said set of metal beads over at least a portion of said preliminary workpiece external surface area, and
- (v) heating said preliminary workpiece and permitting said preliminary workpiece to cool, wherein said heating and cooling is sufficient to form a rigid bond between said metal beads and said portion of said preliminary workpiece external surface area, thereby forming a final preliminary workpiece;
- (b) inserting said final preliminary workpiece into a mold;
- (c) providing a molten second metal;
- and
- (d) pouring said molten second metal into said mold so that it flows about and covers said beads and permitting said molten second metal to cool, thereby forming an article made of said second metal, which is mechanically interlocked to said beads, clad by said first metal.
