Wear is a cause of failure in many engineering components especially involving high speed movement. Wear normally related to the surface roughness of the material and it's rate is high when two rough surfaces are in relative motion. Surface roughness of the material is commonly be measured using stylus profilometer. However there is limitation using of this method due location of the surface is inside the machine. The experimental work done with 250 kHz as an input frequency propagates through various artificial surface roughnesses, and then all responses are recorded. Results show that frequency of 250 kHz give a high potential in surface roughness identification.
