Understanding the effect of particulate erosive wear on coatings or materials is critical, whether you are developing a new product or looking to optimise existing plant.
Particulate erosive wear is caused by the impact of solid particles against the surface of an object, which gradually removes material from the surface. Our tests and expert analysis will give you insight into how your coatings or materials will perform in specific environments.

Our particulate erosive wear testing service
We will work with you to design bespoke tests which simulate the relevant type of particulate erosion, using sand in water or sand in air.
- In our water-sand (slurry jet) erosion test method, we mix sand with water before firing it through a nozzle onto the surface of a material.
- The air-sand erosion test method, which conforms to ASTM-G76, involves adding dry sand to a fast-moving dry air stream and accelerating it down a tube onto a test piece.
For both types of test, samples are subjected to the conditions for a set time. Tests are repeated three to five times to ensure consistency and accuracy.
Post-test analysis
- We weigh each sample before and after exposure to calculate mass loss.
- If we know the material density, we can determine volume loss.
- We can also use 2D and 3D profilometry equipment to measure volume loss directly.
- You’ll receive a comprehensive report detailing the results and our analysis, and we will be happy to discuss the findings with you.
- The results can be used to rank materials or coatings for resistance to erosion under your specified conditions.
