Understand the different types of corrosion—like uniform, galvanic, pitting, and crevice—and learn effective prevention methods such as coatings, cathodic protection, andmaterial selection.“ General Corrosion (Uniform Attack Corrosion) Definition: Corrosion that occurs uniformly over a large surface area. Example: Rusting of iron in the atmosphere. Prevention: Use of corrosion-resistant materials (e.g., stainless steel). Application of protective … Read more
Theories of Corrosion is given below Theories of Corrosion are natural process that results in the deterioration of materials, usually metals, through chemical or electrochemical reactions with their environment. The primary theories of corrosion include acid corrosion, dry (chemical) corrosion, and galvanic (electrochemical) corrosion 1. Acid Corrosion (Electrochemical Corrosion in Acidic Environment): Mechanism: Occurs when … Read more
Overview of Emetics: Emetics are agents used to induce vomiting, primarily to remove toxic substances from the stomach before absorption into the bloodstream. They work by activating the body’s natural vomiting reflex, involving both the central nervous system and the gastrointestinal tract. Mechanism of Action of Emetics: Vomiting, or emesis, is regulated by the brain’s … Read more
