In this proceeding. the compositions of the T-30 turbine oil with liquid rubber. Co. Ni. Zn. Mg and Ba salts of the natural petroleum acids (NPA) boiling in the range 220-340 o C and nitro compounds which are produced on the basis of C 14 H 28 α-olefi ns have been investigated in different ratio and contents as metalworking fl uids (MWF). The physical and chemical properties of the produced compositions have been studied. and the morphology of inhibited carbon steel surface was analyzed and characterized by using Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) techniques. The effect of the temperature on the inhibition effi ciency and thermodynamic parameters have also been reported. The thermal analyzer was used for the thermogravimetric analysis (TG/DTA) of the prepared MWF. The experiments have been operated with different concentrations of the inhibitor on the steel plates in condensation and environment phases in the experiment chamber.

The physical and chemical properties of the produced compositions have been studied and the morphology of inhibited carbon steel surface was analyzed and characterized by Fourier transform-infrared (FT-IR). Effect of temperature on inhibition efficiency and thermodynamic parameters have also been reported. STA-449 F3-thermal analyzer was used for the thermogravimetric analysis (TG/DTA) of the prepared conservative liquids. The researches have been operated with different concentrations of inhibitor on the steel plates in condensation and environment phases in the experiment chamber called «corrosionbox».
