Process for vacuum melting and spurting of titanium-cobalt-manganese-scandium alloy

Abstract

The invention relates to a process for vacuum spurting and melting of a titanium-cobalt-manganese-scandium alloy, which is characterized by comprising the following step: by using a thermodynamically-stable pure graphite crucible, melting a titanium-cobalt-manganese-scandium active alloy in a positive-pressure atmosphere. Compared with other vacuum metallurgy technologies, such as electron beam and plasma arc melting, vacuum consumable melting and the like, the vacuum spurting and melting technology provided by the invention has the advantages of low equipment cost and simple process, is convenient to operate, and greatly lowers the alloy manufacturing cost, thereby realizing the practical application of the titanium-cobalt-manganese-scandium alloys. Besides, the process for vacuum melting of a titanium-cobalt-manganese-scandium alloy can prevent the crucible material from reacting with active elements in the alloy in the melting process, lowers the oxygen content in the alloy, reduces the volatilization of low-melting point elements and improves the purity of the melted alloy.

Description

technical field [0001] The invention relates to vacuum metallurgy technology, in particular to a process for vacuum melting and sputtering titanium-cobalt-manganese-scandium alloy. Background technique [0002] Under the current metallurgical technology conditions, titanium-cobalt-manganese-scandium alloy series materials are easy to oxidize and volatilize because of their high melting point. The alloy is melted in a vacuum in a conventional clay graphite crucible. The alloy liquid will be polluted by the crucible material and volatilized by low melting point elements As a result, the smelting process cannot be carried out normally, and the quality standard required by the alloy cannot be reached. At present, most foreign countries use advanced vacuum plasma melting technology to smelt such alloys, which is expensive and expensive.

[0002] Under the current metallurgical technology conditions, titanium-cobalt-manganese-scandium alloy series materials are easy to oxidize and volatilize because of their high melting point. The alloy is melted in a vacuum in a conventional clay graphite crucible. The alloy liquid will be polluted by the crucible material and volatilized by low melting point elements As a result, the smelting process cannot be carried out normally, nor can it fail to meet the quality standards required by the alloy.

At present, most foreign countries use advanced vacuum plasma melting technology to smelt such alloys, which is expensive and expensive.
