In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by appl...

We demonstrate an approach for determining the “effective” Ehrlich-Schwoebel ES step-edge barrier, an important kinetic constant to control the interlayer mass transport in epitaxial growth of thin films. The approach exploits the rate difference between the growth and/or decay of an adatom and a vacancy twodimensional island, which allows the “effective” ES barrier to be determined uniquely by...

in this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. in this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

In an internal combustion engine, the heat energy approximately one third of total fuel input energy is converted to useful work. Since the exhaust gas temperature is not equal environmental temperature, so lot of heat energy lost with hot gases. Also heat energy is lost in cooling of engine. If we recovered heat energy which lost in cooling instead on crankshaft as useful work, then increase t...
