Engineering Chemistry and Chemical Principles


This section provides an overview of chemistry relevant to engineering applications, including material behaviour, chemical reactions and fundamental principles used in design and manufacturing.

Understanding chemical properties is important in areas such as corrosion, material selection, lubrication, energy systems and manufacturing processes.

What is Engineering Chemistry?

Engineering chemistry focuses on the application of chemical principles to solve practical engineering problems. This includes understanding how materials react, degrade, and perform under different environmental and operating conditions.

Importance in Engineering

Chemical principles are essential for selecting materials, preventing corrosion, improving durability and understanding chemical processes in manufacturing and energy systems.

Main Areas of Chemistry Covered

  • Fundamentals: Atomic structure, elements and compounds.
  • Physical Chemistry: Thermodynamics, reaction rates and energy changes.
  • Inorganic Chemistry: Metals, corrosion, oxidation and material behaviour.
  • Organic Chemistry: Polymers, fuels, lubricants and chemical reactions.

Chemistry Topics

Chemistry can be broadly defined as the study of matter and its interactions.   The chemistry webpages also include notes dealing with physical chemistry which is concerned with the physical principles resulting in the chemical reactions between matter.

Important Note

The pages on this site only to provide outline information on chemistry which is useful to mechanical engineers.  For more detailed, specific information users are advised to use the links at the foot of each page..
