The Molybdenum Nickel Alloy sputtering target is an alloy target made with molybdenum and nickel, and it has many positive qualities, and is able to be made in various dimensions to allow for sputtering coating in multiple industries. Nickel-molybdenum alloy targets are the materials that get bombarded in a high vacuum with the use of physical vapour deposition methods (mainly magnetron sputtering), where the atoms or molecules get sputtered and are deposited on a substrate (like glass, silicon wafers, or plastics), forming a thin, uniform nickel-molybdenum alloy coating. Molybdenum-nickel alloys demonstrate good resistance to corrosion in a variety of chemical environments, which allows the deposited films to have a long service life and to be stable under different working conditions, and also to have less performance-damaging degradation due to corrosion. In a certain range, the alloy physical properties, including hardness, resistivity, etc., can be varied to meet the specific demands of trying so that sputtered film properties can be fine-tuned in several use application conditions.
The Preparation Technology of Nickel Molybdenum Alloy Target
Preparation of the Raw Material: Select high-purity nickel powders (purity ≥99.95%) and molybdenum powders (purity ≥99.95%) and carefully measure their weights for the target alloyed composition (e.g. Ni-10Mo, Ni-20Mo, and so on).
Shaping: The preferred method is through cold isostatic pressing. The blended powders are placed in an elastic mould and are pressed in a range of 150-200MPa to produce a green blank of a desired strength. The green blank is placed inside a vacuum or hydrogen-guarded furnace and is subjected to pre-sintering in the range of 1000-1200℃, wherein the purpose is to eliminate the residual interstitial gases of the powders, form the alloy phase, and improve the density of the green blank.
Hot pressing the Sintering: Sintering under vacuum for 2-4 hours at a pressure of 30-50MPa and at a temperature of 1200-1400℃. The high pressure at high temperature facilitates the bonding of the particles and is needed at this time for the process.
Machining: The sintered blank is machined into the precise dimensions and shapes required by the customer, and the welding surface with the back plate is guaranteed to have extremely high flatness and smoothness.
Applications of Nickel-Molybdenum Alloy Sputtering Target
Thin-film Solar Cells: Used as back contacts in thin-film solar cells such as CIGS (copper indium gallium selenide).
Semiconductor Sector: Used as diffusion barrier layers to eliminate (and prevent) interdiffusion of various metal layers (i.e. damaging silicides and short circuits in copper interconnects and silicon substrates).
Decorative and Protective Coatings: Excellent wear and corrosion resistance. Nickel-molybdenum alloy films can be deposited on surfaces of various objects such as watches, eyeglasses, bathroom fixtures, automotive parts, etc. Thus, they are protected and also acquire a metallic lustre and a shiny, pleasing appearance.
Coatings for Corrosion Resistance: Offer protection against chemical corrosion and wear for sensitive components in chemical and marine engineering, as well as in medical devices.
