Abstract
A centrifugal casting of tubular form exhibiting an outer layer of a heavy (high density) metal having a high melting point, an inner layer of a lighter (low density) lower melting point metal and an intermediate zone where the two metals vary continuously and oppositely as to concentration from the inner layer to the outer layer; in the case of a tube these layers are the inner diameter (I.D.) and the outer diameter (O.D.).
Claims6
A centrifugal casting having at and near the outside surface a first zone having a high concentration of a dense metal alloyed with a low concentration of a less dense metal;
- a second zone having a higher concentration of the less dense metal, higher than in the first zone, alloyed with a lower concentration of the dense metal, lower than in the first zone, at and near the inside surface;
- and a transition zone between the other two zones where the concentration of the less dense metal is continuously increasing radially in the direction of the inside surface.
A tubular centrifugal casting having a low concentration of a less dense metal and a high concentration of a dense metal combined in a zone at and near the outside;
- having a lower concentration of the dense metal, compared to the outside zone, and a higher concentration of the less dense metal, also compared to the outside zone, combined in a zone near the inside of the casting;
- and having a transition zone between the other two zones where the less dense metal exhibits a continuously increasing concentration radially inward in the direction of the inside zone.
