Corrosion

Introduction to corrosion Corrosion is a natural process that refers to the gradual deterioration or degradation of materials, particularly metals, due to chemical reactions with their surrounding environment. It is often characterized by the formation of unwanted compounds or oxides on the surface of the material, leading to the weakening or destruction of its structural integrity. Corrosion occurs when metals are exposed to substances like oxygen, water, acids, or salts, which can initiate chemical reactions with the metal surface. These reactions result in the formation of corrosion products, such as rust or tarnish, which are typically less durable and protective than the original metal. Corrosion can occur in various forms, including uniform corrosion, localized corrosion (such as pitting or crevice corrosion), galvanic corrosion, intergranular corrosion, and stress corrosion cracking. The severity and rate of corrosion depend on factors such as the type of metal, the nature...

Metals in Daily Life

  Metals play a crucial role in our daily lives and are utilized in numerous ways. Some common uses of metals in everyday life include: Use of metal in construction Metals are widely used in construction due to their desirable properties such as strength, durability, and versatility. Here are some common ways metals are used in construction: Structural Framework: Metals, particularly steel and aluminum, are commonly used as the primary structural materials in buildings and infrastructure. They provide the strength and load-bearing capacity required to support the weight of the structure and resist external forces such as wind and earthquakes. Reinforcement: Reinforcing steel bars, also known as rebars, are extensively used in reinforced concrete construction. The rebars provide tensile strength to the concrete, enhancing its ability to withstand tension forces. Roofing and Cladding: Metal roofing materials, such as steel, aluminum, or copper, are popular due to their durabil...
