|dc.description.abstract||The interest in nickel-tungsten alloys has increased in recent years from many coating technology researcher due to their superior properties, such as high tensile strength, premium hardness, abrasion resistance, good resistance to acids, and high melting temperature. However, nickel-tungsten alloys have some problems, for example, current efficiency is too low due to hydrogen evolution reaction (HER) during electrodeposition process and electrodeposited nickel-tungsten has continuous crack on surface because of high internal stress. Internal stress is induced from difference between volume of nickel atom and tungsten atom. Because of these reasons, using nickel-tungsten in the industry has a difficulty. In here, this thesis is classified into two themes. In the first session “Electro-deposition of Nickel-Tungsten thin film”, purpose of study is synthesis of nickel-tungsten thin film without crack. Nickel tungsten alloys were synthesized by induced coelectrodeposition method. After nickel tungsten alloys were tailored and patterned with tungsten contents by alternative current density. In the second session “Synthesis of nickel tungsten micro flake using sonoelectochemistry”, Nickel tungsten micro flakes were synthesized by property of nickel tungsten high internal stress. Nickel tungsten micro flakes were synthesized by electrodeposition and ultra-radiation.||-|
