N2 - The potential of a chemical vapor deposition technique to produce Pt coatings with high surface area contacts of an electrophysiological diagnostic electrode has been firstly demonstrated. On the first step, a Pd layer has been deposited in the hydrogen atmosphere from Pd(hfac)2 on the contacts made of stainless steel. On the second step, the top functional Pt coatings have been deposited in the oxygen atmosphere from Pt(acac)2. The effect of deposition parameters and the Pd sublayer on the microstructural and electrochemical characteristics of Pt coatings has been studied. The capacity and impedance values of samples are 22-198 mC·cm-2 (0.1M H2SO4, 100 mV/s) and 56-167 Ω (at 120 Hz), respectively.
