Abstract
New self-healing argents instead of SiC were investigated in the present study. Mo-Al, Nb-Al, Ti-Al alloys were determined to be suitable for self-healing material, based on Clarke number, melting point and oxidation behavior obtained from many references. The oxidation kinetics of Mo-Al, Nb-Al, Ti-Al alloys were also estimated by means of TG-DTA analysis. All the peak-temperatures of the alloy's oxidations were 〜300℃ lower than that of SiC. Furthermore, TiAl particle exhibited lower activation energy of its oxidation than SiC particle and were bonded strongly to alumina by the oxidation heat. Thus, TiAl particle was determined to be the most attractive candidate for new healing argent.
