How to select a liner material?
The key things to think about when selecting a liner material include the following:
- What is the material causing the abrasion? (Particle size? Hardness?)
- What is the angle of impact?
- What is the drop height or the particle velocity at impact?
- Is the application wet or dry?
- Are there other attacking chemicals present?
- Budget considerations?
What’s the Difference Between Impingement vs. Sliding Wear?
- Tribology is the scientific/engineering field for the study of interacting surfaces in motion.
- We focus on 2 distinct end members when it comes to wear, sliding/rubbing and impingement.
- Impingement wear is the situation where particles impact and erode a surface.
- Rubbing/sliding wear, on the other hand, occurs when two materials under load slide against each other. (Mason, 2002)
- What differentiates these 2 wear mechanisms? Impact Angle
- The other critical mechanism we must be aware of is Impact. Our liner material can fail if it is crushed and over compressed.
