ABSTRACT

Due to the cutting head geometry, the increase of scribe depth also increased the scribed width. Consequently, a general conclusion can be extended to state that the scribing width and scribing depth has little effect on the corrosion test results. The most striking difference in the corrosion results was caused by the different mode of scribing. In a simplified view, the stationary mode (V shaped) scribe gave the least corrosion and the spinning mode (U shaped) scribe caused severe corrosion.
