Surfaces of titanium aluminides were treated by fluorine either physically using Plasma Immersion Ion Implantation (PI³) or chemically with a F-based polymer. By controlling the fluorination parameters, both treatments improve the oxidation resistance even in the presence of sulfur dioxide (0.1 vol%). No sulfur was detected in the oxide scale although thermodynamic calculations predict the formation of sulfides. The inward diffusion of oxygen and nitrogen in the alloy was found to be reduced in the presence of SO2.

Thin Cr/C film was synthesized on 4Cr10Si2Mo steel substrates by Plasma Immersion Ion Implantation and Deposition (PIIID). The high-temperature oxidation behavior of Cr/C Coating at 900°C for 100 hours in air atmosphere was investigated. The results show that the Cr/C coating on 4Cr10Si2Mo steel by PIIID process has excellent high-temperature resistance and antioxidant properties. After the oxidation behavior for 100 hours, the surface of coated specimen maintains completely and the Cr/C coating has a good bonding force with substrates. The composition of the oxidation scale and the surface morphology were studied by using XRD and SEM. An uncoated sample and a hard chromium plating sample with same substrate took part in the experiment in same condition for comparing.

In this paper, the high-temperature oxidation resistant coating on the TA15 titanium alloy by laser cladding (LC) of the KF110-B4C-Ag mixed powders was analyzed in detail. The scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS) images indicated that a good metallurgy bond between the fabricated coating/TA15 was formed; also the fine/compact microstructure was produced after a cladding process. The oxidation mass gain of TA15 was higher than that of the coating after LC process, which were 3.72 and 0.91[Formula: see text]mg[Formula: see text]cm[Formula: see text], respectively, at 60[Formula: see text]h, greatly enhancing the high temperature oxidation resistance.
