Abstract
Official abstract text for this publication.
A method of making a degradable alloy includes adding one or more alloying products to an aluminum or aluminum alloy melt; dissolving the alloying products in the aluminum or aluminum alloy melt, thereby forming a degradable alloy melt; and solidifying the degradable alloy melt to form the degradable alloy. A method for manufacturing a product made of a degradable alloy includes adding one or more alloying products to an aluminum or aluminum alloy melt in a mold; dissolving the one or more alloying products in the aluminum or aluminum alloy melt to form a degradable alloy melt; and solidifying the degradable alloy melt to form the product. A method for manufacturing a product made of a degradable alloy includes placing powders of a base metal or a base alloy and powders of one or more alloying products in a mold; and pressing and sintering the powders to form the product.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a degradable gun carrier, comprising: placing powders of a base metal or a base alloy and powders of one or more alloying elements selected from the group consisting of as gallium, indium, zinc, and bismuth in a gun carrier tubing mould, wherein the base metal or the base alloy is aluminum or aluminum alloy; and pressing and sintering the powders to form the gun carrier. 2. The method of claim 1 , wherein the powders of the base metal or the base alloy and the powders of the one or more alloying elements are pre-mixed before the placing in the mould. 3. The method of claim 1 , further comprising placing powders of a non-metallic material in the mould before the placing and the sintering. 4. The method of claim 3 , wherein the non-metallic material comprises ceramics. 5. The method of claim 1 , wherein the powders of the one or more alloying elements is selected because it will render the gun carrier degradable in water. 6. The method of claim 1 , wherein the powders of the one or more alloying elements is selected because it will render the gun carrier degradable in fluid having a pH greater than 7.0. 7. The method of claim 1 , wherein the powders of the one or more alloying elements is selected because it will render the gun carrier degradable in fluid having a pH less than 7.0.
