Abstract

Surface energy of stainless steel coupons were increased through the exposure of helium and oxygen atmospheric radio-frequency generated plasma. The increase in surface energy is observed through the contact angle of a water droplet placed on the sample and quantified by Young’s equation. A 5 second exposure test reveals that an oxygen flow rate of 0.20L/min results in the lowest contact angle. Our experiments on the longevity of the treatment shows that at 6 hours after a one-minute treatment, our sample still retains a 35% higher surface energy compared to the control. An analysis of the spectra of the plasma showed that more reactive species are present at lower oxygen flow rates.
