Degradation 2 – Oxidation

Oxidation is one of the most prevalent forms of lubricant degradation, leading to increased viscosity, sludge and varnish formation, acidity buildup, and premature oil failure. Over time, exposure to oxygen, heat, and catalytic materials accelerates oxidation, reducing the effectiveness of lubricants and increasing the risk of equipment damage. Without proper monitoring and mitigation strategies, oxidative degradation can lead to costly downtime, increased maintenance, and reduced asset reliability.

This course provides a comprehensive understanding of oxidative degradation in lubrication systems, exploring its causes, chemical mechanisms, and impact on lubricant performance. Participants will learn about oxidation accelerators, the role of antioxidants in slowing oxidation, and the function of metal deactivators in preventing catalytic oxidation reactions. The course also examines how to extend lubricant life through effective oil selection, condition monitoring, and maintenance best practices.

Designed for maintenance professionals, reliability engineers, and lubrication specialists, this course equips participants with the knowledge and tools to prevent oxidative degradation, optimize lubricant performance, and extend equipment service life.

Course Modules:
Degradation 02 01 – Oxidation Concepts
Understand the fundamental principles of oxidation, how it occurs in lubricants, and its impact on lubricant properties such as viscosity, acidity, and deposit formation.

Degradation 02 02 – Oxidation Cycle
Learn about the oxidation cycle, from the initial reaction of oxygen with base oil molecules to the formation of oxidation byproducts such as acids, sludge, and varnish.

Degradation 02 03 – Oxidation Accelerators
Explore the key factors that accelerate oxidation, including high temperatures, water contamination, metal catalysts, and prolonged exposure to oxygen.

Degradation 02 04 – Primary Antioxidants
Discover the role of primary antioxidants such as phenols and amines in inhibiting oxidation by neutralizing free radicals before they initiate degradation.

Degradation 02 05 – Secondary Antioxidants
Learn how secondary antioxidants, such as phosphates and sulfur-based compounds, work to break down peroxides and slow down the oxidation process.

Degradation 02 06 – Metal Deactivators
Understand how metal deactivators help prevent catalytic oxidation by neutralizing the effects of copper, iron, and other reactive metals that accelerate oil breakdown.

Key Learning Outcomes:

• Understand the chemistry of oxidation and its impact on lubricant performance.
