Surface Treatments and Tribology Elements: An Overview

Slide 1: Introduction to Tribology

Tribology studies friction, lubrication, and wear in materials under relative motion. It plays a crucial role in industrial performance and durability.

Slide 2: Key Influencing Factors

1. Environmental conditions (temperature, pressure, humidity)
2. Intermediate materials (lubricants, contaminants)
3. Load & motion (friction effects on surfaces)
4. Competing components (stress-inducing elements)

Slide 3: Types of Lubricants

1. Mineral Lubricants – Low-cost, limited performance
2. PTFE-Based Lubricants – High chemical & thermal resistance
3. Silicone Resins – Stable but expensive
4. Plasma Lubrication – Prepares surfaces for further treatment
5. Parilene Coatings – Advanced protection & lubrication

Slide 4: Quality Control Methods

1. IR Spectrophotometry (detects contaminants)
2. Coefficient of Friction Testing (evaluates lubrication efficiency)
3. Mechanical Strength Tests (measures load & durability)

Slide 5: Plasma Treatments

Enhances tribological properties through:

1. Micropurification – Removes contaminants
2. Etching – Improves surface adhesion
3. Activation – Boosts lubricant bonding
4. Polymerization – Creates protective films

Slide 6: Choosing the Right Treatment

1. Mineral lubricants – Cost-effective, but low performance
2. PTFE-based lubricants – Balanced cost & effectiveness
3. Plasma lubricants – Useful for assembly & selection
4. Parilene coatings – Best for extreme conditions

Slide 7: Final Thoughts

Surface treatments and tribology impact various industries. Choosing the right method ensures durability, efficiency, and cost-effectiveness.
