Description

The determination of surface roughness is an important measurement in many manufacturing processes and corrosion detection schemes. These applications vary widely from the detection of surface weathering and unwanted wear of our national monuments to the detection of corrosion under insulation on the interior of aircraft skins. Besides the need for nondestructive surface inspection techniques there is also a need to monitor surface roughness during processing. One example of this is the molten alloy spray forming process where the roughness of the freshly sprayed surface is considered one of the best indicators of material end quality.
