US 9,789,544 B2 · Methods of manufacturing oilfield degradable alloys and related products

Abstract

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.
