Circumferentially oriented Ni cylindrical thin films for torque sensor applications

Phase alignment and crystal orientation of Al3Ni in Al–Ni alloy by imposition of a uniform high magnetic field

“…To produce this kind of materials, a variety of technological methods have been developed. These methods include electro-deposition [1], chemical deposition [2], molecular beam epitaxy [3], solidification process [4,5] and so on. However, many traditional techniques are relatively expensive or complicated.…”

Measurement System for a Magnetostrictive Torque Sensor

“…The material of choice in our study is NiFe because of the excellent magnetostrictive properties of Ni [8] and the considerable magnetic moment of Fe. Also NiFe can be easily electrodeposited which is the selected method for the growing of a thin film on the shaft [9][10].…”

“…Conventional electrodeposition devices typically result in non uniformities and microcracks on the surface of the thin film due to tensions built in during the electrodeposistion process [8][9]. In order to attain better control on the sample preparation process, the following parameters must be controlled: the current density, the bath's temperature for higher solubility and the velocity of revolution of the bath for higher uniformity in the NiFe deposition.…”

A practical investigation on nickel plated copper heat spreader with different catalytic activation processes for flip-chip ball grid array packages

“…2c shows that nickel and copper are the elements deposited on this layer. The thin layer of Ni-Cu alloy whose thickness is less than 1 micrometer produced by direct current plating from a sulphate type bath (using an aqueous citrate electrolyte containing Ni and Cu sulphates) and the alloy composition was varied by changing the deposition current density [11][12][13][14][15]. The followings are the cathodic reactions for nickel-copper electrodeposition:…”
