Some thoughts on neural network modelling of micro-abrasion-corrosion processes [PDF]

, 2008
There is increasing interest in the interactions of microabrasion, involving small particles of less than 10 μm in size, with corrosion. This is because such interactions occur in many environments ranging from the offshore to health care sectors.
