Several applications of coatings include their use on the surfaces of metallic parts in the hottest areas of gas-turbine engines Clarke et al. Coatings have also been demonstrated to improve the high-temperature oxidation resistance of plain steel Das et al.

Ramirez a, c. Inhibition of the formation of intermetallic compounds in aluminum-steel welded joints by friction stir welding. Formation of deleterious phases during welding of aluminum and steel is a challenge of the welding processes, for decades. Friction Stir Welding FSW has been used in an attempt to reduce formation of intermetallic compounds trough reducing the heat input. The temperature of welded joints was measured during the process.

The interface of the welded joints was characterized using optical microscopy, scanning and transmission electron microscopy. The microstructural characterization in the aluminum-steel interface showed the absence of intermetallic compounds, which is a condition attributed to the use of welding with low thermal input parameters.

Autores como Jiang y Kovacevic y Watanabe et al. Por otro lado Fukumoto et al. Estos resultados fueron puestos a prueba por Tanaka et al. Igualmente fueron realizadas medidas de temperatura durante el proceso de soldadura empleando termopares del tipo K. Figura 2. El incremento de la temperatura con D E se explica por el aumento en la cantidad de acero involucrado en la soldadura. Frecuentemente parte de la cementita se acumula en la interfase Fig. Figura 3.

Figura 4. Estos resultados se diferencian de las observaciones realizadas por autores como Chen y Kovacevic y Lee et al. Igualmente Murakami et al.

Figura 5. Karfoul et al. Figura 6. En este espectro todos los picos son identificados y no se detecta la presencia de picos adicionales que puedan corresponder a los CIM. Figura 7. Figura 8. Agudo et al. Cuando hay diferencias muy grandes de difusividad entre los elementos, como es el caso del sistema Al-Fe, el enriquecimiento es favorecido en el lado del aluminio, ya que la difusividad del hierro en el aluminio es mayor que en el caso contrario.
