hi, pls describe these sentences in simplest way.specially the words are bolded.thanks
Erosion corrosion is an acceleration in the rate of corrosion attack in metal due to the relative motion of a corrosive fluid and a metal surface.
In offshore well systems, the process industry in which components come into contact with sand-bearing liquids, this is an important problem.

Original:
Erosion corrosion is an acceleration in the rate of corrosion attack in metal due to the relative motion of a corrosive fluid and a metal surface.
Simplified:
Erosion corrosion is an increase in corrosion of metal due to a difference in the motion between a corrosive fluid and a metal surface.

Original:

Simplified:
In wells, where sandy fluids come in contact with metallic parts, erosion corrosion can be a problem.
