Electrochemical impedance spectroscopy of PVD-TiN coatings on mild steel and AISI316 substrates

Electrochemical impedance spectroscopy of carboxylic-acid terminal alkanethiol self assembled monolayers on GaAs substrates

“…3(b) represents conduction through the alkane chain length of the monolayer [55]. Hence, R IM can be used to quantify the quality of the monolayer, as has been applied previously to characterize SAMs on Au [36,37], and this is based on prior work of coatings on metals [56,57]. The fitting results obtained from the application of the two equivalent circuit models from Fig.…”

Tribological and electrochemical performances of Cr/CrN and Cr/CrN/CrAlN multilayer coatings deposited by RF magnetron sputtering

“…The total polarization resistance (R p ) is taken as the sum of all resistances obtained from the EIS results [31,33,35,38,40]:…”

Microstructure and electrochemical behavior of Ti-coatedZr55Al10Ni5Cu30 bulk metallic glass

“…The case is even more severe if the coating systems are exposed to an aggressive environment, for example, a Cl À -containing solution due to the aggressive effects of chloride ion in promoting pitting corrosion. On further increasing the immersion time, the impedance enhanced slightly after 48 h immersion as compared to 24 h immersion induced by the blocking of pinholes by corrosion products [20] from the solution/substrate interface. That is, after 48 h immersion, the corrosion products plugged in the pinholes and the electric resistances of corrosion products were higher than that of solution.…”
