Innovative Research Trends in the Application of Thermal Barrier Metal Coating in Internal Combustion Engines

Industrialization and urbanization reflects in the energy demand consequences of that the world is constantly facing challenges toward the hazardous emissions from various industries and transportation systems. The emissions play a vital role in global warming, ozone layer depletion and imperil to the ecosystem. The survival from adverse effects due to emissions can be significantly controlled by attaining technological advancements in emission reduction. Many researchers are attracted towards engine emission controlled by adopting the metal coating on combustion chamber surfaces. Some of the researchers also attempted with ceramic coating for the components viz piston, engine head etc. The kind of metal coatings acts as thermal barrier, and this thermal insulation decreases the rate of heat transfer from the combustion chamber by restoring the heat in, itself only and controls the exhaust gas emissions. This research paper, details the various trends and innovations about the metal coating in automobile engine application. The results are evitable, in the perception of engine performance enhancement and a significant reduction of engine emission. (C) 2017 Elsevier Ltd. All rights reserved.
