The efficiency of the inhibitor technology was evaluated gravimetrically on aluminum specimens under static and dynamic heat-transfer conditions. Testing techniques and results are discussed. The thermal properties of the protective film and the coolant were evaluated under dynamic heat-exchange conditions. Information on composition and structure of the protective film formed under conditions of heat-transfer was obtained through the use of microscopy and Fourier transform infrared spectrometry (FTIR).
