Abstract: Use of chemical corrosion inhibitors has been recognized as one of the effective way of controlling rebar corrosion in cementitious composites. The effect of these chemicals on various physical properties of cement such as setting time, pH, and Compressive strength needs to be explored before use. In the present investigation the effect of some of the commercially available corrosion inhibitors on setting time, pH and compressive strength has been studied. In the next part of the study electrochemical test involving these chemical corrosion inhibitors were also conducted. Corrosion kinematic parameters have been estimated using potentio-dynamic polarization tests.

Abstract: Thermal barrier coatings (TBCs) have beendeveloped to protect metallic and Si-based ceramic components from high temperature environmental attack and thermal stresses in structures and machine components across a wide range of industries and applications.Zirconia-yttria based oxides and (Ba,Sr)Al2Si2O8 (BSAS)/mullite basedsilicates have been used as the coating materials. There are several thermal barriercoating techniques with a objectives of reductionof maintenance costs, increase of the working temperature, reduction of thermal loads, resistance increase to erosion and corrosion and reduction of the high temperature oxidation. Thispaper incorporates a brief review on post researches on several recent activities in the field of modern TBCs, focusing on advanced coating techniques and in addition some advances coatings materials are described.
