Electrochemical impedance spectroscopy is very well suited to study paints and coatings used to prevent corrosion. There are even ISO norms developed for such tests [675] and technical notes from the equipment manufacturers [676, 681], This topic has also been reviewed in several books [473-475].

Titanium and its alloys are used as technical materials mainly because of the low density (q = 4.5 g cm ) of Ti at technically useful levels of mechanical properties, and the formation of a passivating, protective oxide layer in air, which leads to a pronounced stability in corrosive media and at elevated temperatures. Further useful properties to be noted are its paramagnetic behavior, low temperature ductility, low thermal conductivity (/c = 21W m K ), low thermal expansion coefficient (A = 8.9x10 K l ), and its biocompatibility which is essentially due to its passivating oxide layer. 

Plot of corrosion potentials of pure aluminum and binary aluminum plus copper alloys, plus the two stoichiometric precipitates. The binary alloys were fully solution heat treated and quenched as rapidly as possible to retain the maximum amount of copper in solid solution. Note that the addition of copper raises the corrosion potential of pure aluminum by about 0.14 V. (Courtesy of Alcoa Technical Center, Marsha Egbert.)... 

This TLJP is important for pH measurements at elevated temperatures. Key values of high temperature parameters for some usual 1,1-electrolytes are reported in ref. [79], and the equations for solid electrolyte-containing cells with temperature gradient are presented as well. Important note specially marked in later review [80] is related to the changes of the customary transport numbers with temperature (at elevated temperatures, NaCl is more suitable for UP elimination than KCl). Quantitative information for both chlorides is available in ref. [81]. TLJP at solution/solution boundary is also of interest for applications related to corrosion. In this case the medium is technical water being rather diluted electrolyte, and not so low potential drops can arise (see example of TLJP research, e.g., in ref. [82]). 

Decide which coating metal will withstand the expected environment and which of the coating metals can be applied to adequate thickness with good coverage. Note The danger of microcracking of thickly applied chromium, rhodium, or hard metals (corrosion rate of deposited metal from economical and technical point of view). 

These examples clearly illustrate the potential interest of cathodic protection to control wear in technical tribocorrosion systems. Note that in these systems the corrosion rate was already minimised to negligible values using appropriate...
