Diffusion Treatment

In this paper, aluminum films were deposited on the TiAl alloy by multi-arc ion plating (MAIP) and subsequently diffusion-treated under 720°C for 4h. It is revealed by XRD and SEM/EDS that the film consisted of Al turn to an outer Al2O3 layer and inner TiAl3 layer after diffusion treatment. Cyclic oxidation tests show that the surface of the film formed a compact and continuous Al2O3 layer that prevents the TiAl substrate from oxidation, and the oxidation rate of the specimen with Al diffusion film is as low as 1.84 mg/cm2. The MAIP Al film after diffusion treatment is effective in improving the high-temperature oxidation resistance of TiAl alloys.

High Temperature Oxidation Behavior

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.

Kinetics Of

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.

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.

Abstract: NiCoCrAlYSiHf coatings have been prepared by arc ion plating (AIP) on CrNi3MoVA steel ,which their microstructure and isothermal oxidation behavior at 950°C studied using SRD,SEM and EDAX. The results indicate that NiCoCrAlYSiHf coatings substantially increase the high-temperature oxidation resistance of CrNi3MoVA steel and the oxidation process was retarded mainly by the presence of α-Al2O3 oxide scale on the coating. Meanwhile, the major diffusion occured between the substrate element Fe and the coating element Co while Cr mainly distributed in the coating.

Diffusion Treatment

In order to improve the high-temperature oxidation resistance of the hydrogen-resistant steel, Al coatings were firstly deposited on the hydrogen-resistant steel by arc-ion plating and then the thermal diffusion treatment was used to produce the Al-based composite coatings on the hydrogen-resistant steel. The effect of thermal diffusion parameters on the structure of Al-based composite coatings was studied. The crystal structure, composition and morphology of Al-based composite coatings were analyzed by using X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). The results showed that the double inner diffusion layer was formed on Al coatings treated at 700[Formula: see text]C. And the single inner diffusion layer with uniform composition distribution could be formed on Al coatings treated at 950[Formula: see text]C. The Al-based composite coating prepared by thermal diffusion treatment at 950[Formula: see text]C had a dense and thick [Formula: see text]-Al2O3 surface layer, and it exhibited good high-temperature oxidation resistance.
