Gradient Zr/ZrN/Zr layer was deposited as a diffusion barrier between the NiCrAlYSi The overlay coating and Ni-base superalloy DZ125 by arc ion plating(AIP). The microstructure and high-temperature oxidation behavior of the diffusion barrier were studied. The results show that the gradient diffusion barrier is homogeneous and compact, and has strong bond strength with the substrate. The diffusion barrier is composed of three layers, among which the inner and outer layers are rich in Zr, and the middle layer is rich in ZrN. The main phase structure of the diffusion barrier is ZrN(200). During high temperature oxidation at 1100°C, the Zr/ZrN/Zr/HY3 compound coating system presents excellent oxidation resistance.

High temperature oxidation behavior of nanocomposite films is very important characteristics for application of machining and cutting tools. Quaternary Cr–Al–Si–N nanocomposite films with various compositions were deposited onto WC-Co and Si wafer substrates using a filtered arc ion plating technique. The composition of the films were controlled by different combinations of CrAl2 and Cr4Si composite target power in a reactive gas mixture of high purity Ar and N2 during depositions. The instrumental analyses revealed that the synthesized Cr–Al–Si–N films with Si content of 2.78 at.% were nanocomposites consisting of nano-sized crystallites (3–7 nm in dia.) and a thin layer of amorphous Si3N4 phases. The nanohardness of the Cr–Al–Si–N films exhibited the maximum values of ~42 GPa at a Si content of ~2.78 at.% due to the microstructural change to nanocomposite as well as solid-solution hardening. The Cr–Al–Si–N film shows superior result of oxidation resistance at 1050 °C for 30 min in air. Based on the XRD and GDOES analyses on the oxidized films, it could be revealed that the enrichment of Al (17.94 at.%) and Cr (26.24 at.%) elements in the film leads to form an Al2O3 and Cr2O3 layer on the Cr–Al–Si–N film surface. Therefore, in this study, the microstructural changes on the mechanical properties and oxidation behavior with various compositions in the Cr–Al–Si–N nanocomposite films were discussed and correlated with the deposition parameters.

The high temperature oxidation behavior of the TiAl(La)N coating, which was deposited on a steel substrate by the arc-ion plating method, was investigated at 700, 800 and 900oC in atmospheric air. The oxidation kinetics of the coating were mainly governed by the inward diffusion of oxygen and outward transport of nitrogen. The oxide scale was porous, nonadherent, and prone to cracking, indicating the oxidation resistance above 700oC is poor.

ABSTRACTOxidation behavior of alumina forming ferritic stainless steel (FeCrAl type stainless steels) grades APM and APMT, which are candidate alloys for fuel cladding, was studied using thermogravimetric analysis under dry air condition, and compared to that of ZIRLO®. In addition to the dry air condition, we also studied the high temperature oxidation behavior of APM and APMT under 100% steam condition in order to compare the effect of environment on the oxidation behavior of these alloys. APM and APMT showed an excellent oxidation resistance at high temperatures compared to ZIRLO® under dry air condition due to a stable Al2O3 oxide scale formed at the surface. Under steam condition, the oxidation rate of APM and APMT was found to be higher compared to that under the dry air condition.
