Introduction to Liquid Lubricants | Prof. Ashlie Martini | Tribology Webinar

Lubricants are essential in tribology for reducing friction, minimizing wear, and enabling reliable machine operation. In this TriboNet webinar, Professor Ashlie Martini, Chair of Mechanical Engineering at UC Merced and leader of the Martini Research Group, provides an introductory presentation on liquid lubricants for a broad tribology audience.

This talk covers the fundamentals of lubricant composition and classification, from base oils to additives and grease thickeners, and explores how emerging technologies—especially electric vehicles (EVs)—are shaping the future of lubricants.

Key Topics Covered:

The primary functions of liquid lubricants

Base oils: biological, mineral, and synthetic

Additives: viscosity modifiers, oxidation inhibitors, and boundary additives

Grease thickeners and their function

Lubricant classification: API groups, SAE grades, and ISO viscosity grades

The Viscosity Index and why it matters

Sustainable and “green” lubricants

Challenges and opportunities in EV lubrication
