“…It is known that among the use of Ni is increasing the resistivity of Cu. Considering resistivity of nickel and copper is 7.3 cm 1.7 cm respectively [21] then plating Ni to Cu will increase the resistivity. But there are things that should not be forgotten, which is the ordering atomic structure in a material.…”

The purpose of this research is studying microstructure, the resistivity of Cu/Ni film produced by electroplating on the various mass fraction of Ni in the electrolyte. Then the film is tested for its performance as a temperature sensor. The electrolyte solution was made from mixing of NiSO 4 , NiCl 2 , H 3 BO 3 , and H 2 O. Plating was conducted on power 1.5 V and 60°C bath temperature. The results showed deposits containing Ni and NiO. The X-ray diffraction parameters of Ni[111] and NiO[111] such as intensity, d-spacing and grain size on variations of Ni mass fraction in solution followed the parameters diffraction of Cu[111]. The resistivity is contributed by competition between those three diffraction parameters. Testing Cu/Ni films for sensing the temperature of liquid nitrogen (0°C to-140°C) shows that all samples have exhibited their performance as low-temperature sensors. The temperature has a linear relationship to the output voltage of the sensor with the sensitivity ranging from 0.7510-3 V/°C to 1.0510-3 V/°C. The highest sensitivity in accordance to the sample produced from 8.83 g Ni in the electrolyte.

“…Tak jak i w innych dziedzinach nauk [18][19][20][21][22][23] tak i w tym przypadku optymalizacja parametrów wiązki laserowej wykorzystywanej w procesie modyfikacji jest zagadnieniem bardzo istotnym. Przy zbyt dużej energii impulsu powierzchnia została uszkodzona, jak to przedstawiono na rysunku 3.…”

Wpływ oddziaływania wiązki laserowej na skłonność tkanin poliestrowych do pilingu Streszczenie. W artykule opisano wpływ modyfikacji powierzchni tkanin poliestrowych z wykorzystaniem wiązki laserowej. Ocenę tendencji do pilingu wykonano w oparciu o analizę obrazów 2D oraz 3D pozyskanych z wykorzystaniem optycznego tomografu koherentnego. Zaobserwowano, pozytywny wpływ obróbki laserowej na zmniejszającą się liczbę poluzowanych pojedynczych nitek wystających ponad powierzchnię tkaniny, a w efekcie końcowym na zmniejszenie powstającego niepożądanego pilingu.

“…Special sensors that can be used to monitor temperatures down to -200°C are still bothering researchers in finding materials and manufacturing methods. Making such temperature sensors is not easy because the electrical and thermal properties of materials at this temperature are very non-linear [8].…”

Given the necessity of cryogenic storage and monitoring cryogenic temperatures is equally important. This study aims to determine the resistance value and sensitivity of copper wire before and after electroplating at 30˚C electrolyte temperature as a low temperature sensor. The electrolyte solution consists of NiSO4 260 g, NiCl2 60 g, H3BO3 40 g and Aquades 1000 mL. Electroplating was carried out with an electrolyte temperature of 30˚C, electrode distance of 4 cm, voltage of 4.5 volts and plating time of 4 minutes. The plating results were analyzed to determine the resistance and sensitivity of the sensor at temperatures from 0 to -160˚C. The results showed that the resistance value of the Cu coil obtained RCu = (1.44 ± 0.00) ohm and the resistance of the Cu/Ni coil RCu / Ni = (1.50 ± 0.00) ohm. The resistance value on the Cu/Ni coil (after plating) is greater than the Cu coil (before plating). While the test results of sensor sensitivity show that Cu and Cu/Ni coils have properties as low temperature sensors. Sensor sensitivity increases after plating. The sensitivity value obtained by Cu coil is S(T) = -1E-06T + 6E-05 and Cu/Ni coil S(T) = -2E-06T + 2E-05. The projection sensitivity at a temperature of -200 ˚C obtained is 0.00046 V/˚C less than the Cu/Ni coil 0.00082 V/˚C. So nickel plating on copper coil at 30˚C electrolyte temperature has successfully improved the sensitivity value of the low-temperature sensor.
