Corrosion refers to the gradual degradation or destruction of a material, usually a metal or alloy, due to chemical or electrochemical reactions with its environment. The most common form of corrosion is the rusting of iron or steel, where the metal reacts with oxygen and water to form iron oxide, commonly known as rust.

Corrosion can take various forms depending on the material involved and the specific environmental conditions. Some common types of corrosion include:

Uniform Corrosion: This is a general attack on the surface of the material, resulting in a relatively even loss of material over the entire exposed area.

Galvanic Corrosion: This occurs when two different metals are in contact with each other in the presence of an electrolyte (such as moisture). The less noble (more reactive) metal corrodes preferentially.

Pitting Corrosion: This is characterized by the localized formation of small pits or craters on the metal surface. It can be more damaging than uniform corrosion because it concentrates the attack in specific areas.

Crevice Corrosion: Occurs in confined spaces or crevices, where the lack of access to fresh oxygen or the accumulation of corrosive substances can lead to localized corrosion.

Stress Corrosion Cracking (SCC): This is a type of corrosion that occurs in the presence of both tensile stress and a corrosive environment. It can lead to the sudden failure of materials under stress.

Corrosion is a significant concern in various industries, as it can compromise the structural integrity and functionality of materials and equipment. Preventive measures, such as protective coatings, corrosion-resistant alloys, and proper maintenance practices, are often employed to mitigate the impact of corrosion.

Today, 22 December 2023, it will start from 8.15 am and will end at 7.10 am on 23rd December. Gita Jayanti is an annual celebration that marks the day when the Bhagavad Gita, one of the most important texts in Hindu philosophy, was spoken by Lord Krishna to Arjuna on the battlefield of Kurukshetra. The Bhagavad Gita is a 700-verse scripture that is part of the Indian epic Mahabharata.

Gita Jayanti usually falls on the Ekadashi day of the waxing moon in the month of Margashirsha (November-December) in the Hindu calendar. On this day, devotees of Lord Krishna and followers of the Bhagavad Gita engage in recitations of the scripture, organize satsangs (spiritual gatherings), and participate in various religious and cultural activities.
The Bhagavad Gita, as well as the epic Mahabharata of which it is a part, is attributed to the sage Vyasa, whose full name was Krishna Dvaipayana, also called Veda-Vyasa.

The Bhagavad Gita is a conversation between Lord Krishna and the warrior Arjuna, taking place on the battlefield just before the Kurukshetra War. It addresses the moral and philosophical dilemmas faced by Arjuna and provides guidance on duty, righteousness, and the path to spiritual realization. Gita Jayanti is a day to reflect on the teachings of the Bhagavad Gita and their relevance in daily life.
