Erosion
The animation below shows particles striking a surface, which is how
the process
of erosion occurs. The different pages on this animation will show how
the particle size, angularity, hardness of the particles affect the
amount and rate of wear.
Note this animation is not quantitative, it is just to show how the
different factors affect the amount of wear.
The removal of material usually occurs by a brittle mechanism. As
the particles
strike the surface cracks form within the material. These extend and
join as time passes and will eventually intersect the surface, meaning
there is now loose material which can removed - do this by pressing
the 'Remove' button:
Larger particles, same shape
Larger particles cause more extensive wear.
Faster moving particles
Faster moving particles cause more extensive wear.
Angular particles
More angular particles result in more extensive wear.
Angle of impact
Shallower trajectories give less extensive wear.
