  • Publication number: 20250051901
    Abstract: A method for the surface treatment of a corrosion-resistant nickel-based alloy and the resulting surface structure of the treated alloy is disclosed. The method includes immersing a nickel-based alloy in a first neutral or alkaline solution to remove surface contaminants, followed by immersing the cleaned alloy in a second neutral or alkaline solution to form functional groups on its surface. Subsequently, a low-temperature heat treatment is performed to form a passivation layer on the surface of the nickel-based alloy. The passivation layer has a surface roughness of less than 0.04 microns and a thickness ranging from 5 nanometers to 200 nanometers. The resulting corrosion-resistant nickel-based alloy comprises a substrate made of the nickel-based alloy and a passivation layer established on at least one surface of the substrate. The nickel content of the alloy is greater than 50%, and the alloy may also contain additional metallic components such as chromium (Cr) and manganese (Mn).

  • Publication number: 20250046544
    Abstract: A mechanical key component and a mechanical keyboard are provided. The mechanical key component includes a circuit board, an elastic element and a key cap. The circuit board is provided with a first sensing electrode. The elastic element is disposed on the circuit board, and a movable portion of the elastic element is connected to a second sensing electrode. The key cap is movably disposed on the elastic element. The elastic element enables the key cap to move between an unpressed position and a pressed position, and the movable portion drives the second sensing electrode to move relative to the first sensing electrode. In response to the key cap being moved between the unpressed position and the pressed position, a coupling capacitance between the first sensing electrode and the second sensing electrode changes to indicate whether the key cap is in the unpressed position or the pressed position.
