Simulation Analysis and Experimental Verification of UV-LIGA Process for High-Aspect-Ratio Ni–Fe Micro-Mold Insert

A study on the wear resistance characteristics of pulse electroforming Ni–P alloy coatings as plated

“…Micro-components can make as active or passive contact mechanism that must exhibit suitable tribological characteristics for service in stern environments. For advanced development, binary electroformed coatings such as Ni-P, Ni-Co and Ni-Fe coatings have been used to replace the electroformed Ni coatings [12,15,16]. Among these, Ni-P material possess high hardness, high strength and other superior mechanical properties, it also exhibits wear and corrosion resistance that makes it valuable in the development on the electroformed nano-scale components.…”

The heat treatment effects on the structure and wear behavior of pulse electroforming Ni–P alloy coatings

“…Based on the micro-component with host and passive contact, it is imperative to have a suitable tribological properties, good anti-oxidize and anti-corrosion ability, as well as high thermal stability in nickel electroforming coatings with binary development, such as Ni-P, Ni-Co and Ni-Fe coatings [2,5,6]. Although Ni-Fe and Ni-Co alloys have good hardness at room temperature, their softening phenomenon are evident when the temperature is rising, the hardness of Ni-P alloy, however, can be enhanced by precipitate strengthened effect which is a result of heat treatment and it promotes the hardness significantly [7].…”

Study of NBT–Pluronic F–127 Gels as 1D UV Radiation Dosimeters for Measurement of Artificial Light Sources

“…Moreover, the maximum annual exposure should not exceed an erythemal-weighted dose of 15 kJ/m 2 (150 SED) for white-skinned people [ 9 ]. Therefore, various measurement methods related to the assessment of harmful radiation doses are used, e.g., electronic meters and photodiodes [ 16 ], photodiodes and actinometers [ 17 ], sensors based on inorganic materials [ 18 ], solutions of photoluminescent dyes and liquid crystal mixtures [ 19 , 20 ] or biological dosimeters [ 21 ]. In addition to such solutions, dosimeters with radiation-sensitive compounds that change color under exposure to UV radiation can also be used, e.g., 1D polymer tablets [ 22 ] and 2D flat polymer films doped with tetrazolium salts [ 23 ], as well as 2D flexible flat textile modified with gels on the surface [ 24 , 25 , 26 ] or printed [ 27 , 28 ] and doped with 10,12–pentacosadiyonic acid polyacrylonitrile fibres [ 29 , 30 ].…”
