Nickel-cobalt-chromium alloy targets, which are mainly composed of nickel, cobalt, and chromium, are planar or rotating targets obtained through technologies such as melting and casting. These alloys are used in many different applications, such as in the semiconductor industry, magnetic recording, optics, and aerospace engineering.
Fabrication Method of Nickel-Cobalt-Chromium Alloy Target
Melting and Casting. Particular amounts of high-purity nickel, cobalt, and chromium are melted in a vacuum using induction melting. Then the alloy molten metal is cast into either graphite or metal molds and resulting in the formation of alloy ingots.
Plastic Processing: The microstructure is refined through processes of hot forging and hot rolling, followed by cold rolling.
Annealing: The material is heated and held at a temperature under vacuum or argon protection to eliminate internal stresses generated during plastic processing and adjust the grain size.
Machining: The heat-treated blank is machined to near its final dimensions using turning, milling, planing, etc.
Applications of Nickel-Cobalt-Chromium Alloy Target
In semiconductor manufacturing, they can be used to prepare conductive layers and barrier layers in semiconductor devices.
In the field of magnetic recording technology, they can be used to manufacture magnetic recording films in hard disk drives.
In the aerospace field, they can be used to manufacture protective coatings for aircraft engine components, etc.
In the energy equipment industry, they can be used for protective coatings on high-temperature components such as gas turbine blades.
