nikkelipõhised

Nikkelipõhised refers to materials or substances that contain nickel as a primary component. Nickel is a transition metal known for its silvery-white appearance, hardness, and resistance to corrosion. It is widely used in various industrial applications due to its unique properties.

The most common application of nickel-based materials is in alloys, such as stainless steel, where nickel improves ductility and corrosion resistance. Nickel is also a key component in superalloys, which are designed to withstand extreme temperatures and harsh environments, making them crucial for aerospace and gas turbine industries. Another significant use is in plating, where a thin layer of nickel is applied to other metals for decorative purposes or to enhance their resistance to wear and corrosion.

Nickel-based compounds also play roles in catalysis, particularly in hydrogenation reactions in the petrochemical and food industries. In batteries, nickel is a vital element, notably in nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) rechargeable batteries, which were once prevalent in portable electronics.

However, nickel and its compounds can pose health and environmental concerns. Nickel is a known allergen, and prolonged exposure to nickel dust or fumes can lead to respiratory problems. Therefore, regulations are in place regarding the handling and disposal of nickel-based materials to mitigate these risks. The extraction and processing of nickel also have environmental implications that are subject to ongoing management and research.
