Fourth Year- First Term Wear and Design Against Wear Failure Chapter 6 Quiz

Wear and Tribology

• Corrosion is a process of material removal that involves a chemical reaction between a material and its environment.
• Tribology is the study of surfaces moving relative to one another, focusing on friction, wear, and lubrication.
• To analyze a wear problem in a machine, it is necessary to determine the type of wear, the wear rate, and the wear mechanisms involved.
• The process of material removal from a sliding or rolling component is known as wear.
• Adhesive wear is generally proportional to load and the distance of sliding.

Focus of Tribology

• The main focus of tribology is to understand and mitigate friction and wear in machines.
• The word 'tribology' comes from the Greek words 'tribos', meaning rubbing, and 'logos', meaning study.
• The function of lubrication in tribology is to reduce friction and wear between surfaces in contact.
• In the mining industry, processes of friction and wear are commonly found in components like crushers and grinding balls.

Applications of Tribology

• Components like brakes and clutches are designed to have high sliding resistance.
• Manufacturing processes, such as machining and metal forming, rely on tribology to reduce wear and friction.
• Machine elements, such as bearings and gear teeth, are subject to friction and wear.
• The main focus of tribology in construction and exploration equipment is to reduce wear and extend the lifespan of components.
• The main goal of transportation methods in relation to tribology is to reduce friction and increase efficiency.
