“…Thin-film platinum resistance temperature sensors are thermoelectric sensors [1,2] that use the principle that the resistance value of platinum linearly changes with temperature within a certain temperature range to measure temperature. Compared with traditional platinum thermal resistance, thin-film platinum resistance temperature sensors have the advantages of a small size, a short response time, good stability, a wide measurement range, high accuracy, and good repeatability [3]. They are widely used, for example, in the aerospace, power, chemical, metallurgy, medicine, and food industries [4][5][6].…”

Platinum-clad nickel composite wires with platinum layer thicknesses of 5 μm and 8 μm were prepared by a cladding drawing process. Oxidation experiments were performed using a muffle furnace at temperatures of 500 °C, 600 °C, 700 °C, and 800 °C for 1 h, 2 h, and 3 h. The oxidized samples were examined for high-temperature oxidation behavior using scanning electron microscopy (SEM) with an energy-dispersive X-ray (EDX) spectrometer attached. The results showed that the interface bond between the platinum cladding and the nickel core wire was serrated and that the thickness of the platinum cladding was not uniform. At low temperatures (500 °C and 600 °C), the diffusion rate of the nickel was low. The composite wire could be used for a short time below 600 °C. When the temperature reached 700 °C and above, the nickel diffused to the surface of the composite wire and was selectively oxidized to form a nickel oxide layer. The research results provide a theoretical reference for the selection of a service temperature for platinum-clad nickel composite wires used as the lead material for thin-film platinum resistance temperature sensors.

The emergence of critical conditions in a meta-stable melt is considered under the influence of two main factors: pre-crystallization super-cooling and overcooling rate. The average density of free energy in such conditions is highly inhomogeneous. External impacts are considered as factors controlling the properties of materials. The solidification of the overcooled meta-stable melt is considered in a quasi-chemical approximation, assuming a transition state corresponding to an ideal solution type system. The finite time of existence of the meta-stable state is taken into account. The dimensions of the structural cell are determined by the ratio between the rate of diffusion and heat removal. The obtained estimate of the structure parameter is in qualitative agreement with the experimental dependence.
