Webb12 apr. 2024 · This study examines the effect of grit blasting on the surface and subsurface characteristics of low-carbon steel substrates under dry and wet environments. Three types of wet environments have been simulated: tap water, saline water, and ethyl alcohol. The variation in average surface roughness with grit size, standoff distance (SOD), and … Webbthe surface of stainless steel sheets. 2.3. Contact Resistivity Measurement Contact resistivity between the carbon paper (0.20 mm thickness) and the stainless steel was measured with the 4-wire method. The pressure of about 1.0 MPa was applied during measurement. The details of this measurement were described elsewhere.12)
