Surface contact angle measurements of plasma coating deposited onto 316L stainless steel (SS) coupons. 316L SS, uncoated stainless steel; DC-TMS: TMS plasma coating using DC power supply; DC-TMS + NH3/O2: TMS plasma coating followed by additional NH3/O2 plasma surface modification using DC power supply; RF-TMS: TMS plasma coating using RF power supply; and RF-TMS + NH3/O2: TMS plasma coating followed by additional NH3/O2 plasma surface modification using RF power supply. Samples were measured under both dry storage and after immersion in simulated body fluid (SBF).
