These TBCs consisted of a duplex TBC and a five-layered functionally graded TBC. NiCrAlY bond coats were deposited on a number of Inconel-738LC specimens using high velocity oxy-fuel spraying (HVOF) technique. For duplex coating, a group of these specimens were coated with yttria stabilized zirconia (YSZ) using plasma spray technique. Functionally graded NiCrAlY/YSZ coatings were fabricated by plasma spray using co-injection of the two different powders in a single plasma torch. The amount of zirconia in functionally graded coatings were gradually increased from 30 to 100 vol. pct. Microstructural changes, thermally grown oxide (TGO) layer growth and damage initiation of the coatings were investigated as a function of isothermal oxidation test at 970°C. As a complementary test, the performance of the fabricated coatings by the optimum processing conditions was evaluated as a function of intense thermal cycling test at 1100°C. Also the strength of the adhesive coatings of the substrate was also measured. Microstructural characterization was analyzed by scanning electron microscopy (SEM) and optical microscopy whereas phase analysis and chemical composition changes of the coatings and oxides formed during the tests were studied by XRD (X-ray diffraction) and EDS (energy dispersive spectrometer). The results showed that microstructure and compositions gradually varied in the functionally graded coatings. By comparison of duplex and functionally graded TBCs oxidation behavior (duplex failure after 1700 h and funcitionally graded TECs failure after 2000 h), thermal shock test and adhesion strength of the coatings, the functionally graded TBC had better performance and more durability.","authors":[{"authorName":"B.

The thermal cyclic life of the TBC system was assessed by furnace cycling at 1050degreesC. The oxidation kinetics were evaluated by thermogravimetric analysis (TGA) at 900, 1000, and 1100degreesC for up to 100 hr. The results showed that the weight gain of the specimens at 1100degreesC was the smallest in the initial 20 hr, and the oxide scale formed on the sputtered Ni-Cr-Al-Y bond coat is only Al2O3 at the early stage of oxidation. With aluminum depletion in the bond coat, NiO, Ni(Cr,Al)(2)O-4, and other spinel formed near the bond coat. During thermal cycling, microcracks were initiated preferentially in the YPSZ top coat along columnar grain boundaries and then extended through and along the top coat. The growth stress of TGO added to the thermal stress imposed by cycling, lead to the separation at the bond coat-TGO interface.

The oxidation behaviors of detonation sprayed TBCs at 1000 and 1100 degreesC were studied. The results indicated that the detonation sprayed TBCs were uniforin and dense, with a few microcracks in the ceramic coats and a rough surface of bond coats. At the high temperature, the dense detonation sprayed ceramic coats with low porosity could obviously decrease the diffusive channels for oxygen and reduce the oxygen pressure (PO2) at the ceramic/bond coat interface. Under the lower oxygen pressure at the interface, it was advantageous to the formation of a continuous protective Al2O3 layer and the growth of a thermally grown oxide layer (TGO) obeyed the fourth power law.
