be developed in the scale or at the oxide/substrate interface. Further spreading of these cracks may lead to scale spallation. Because the cyclic oxidation is conducted between high temperature heating... stress is high enough to cause the duplex oxide layer to crack when the temperature increases from room temperature to 600 ℃. With the increase of oxidation temperature, the tensile stress also......

, as for wear resistance composite coatings used at high- temperature such as combustion engines and casting moulds[4], a good oxidation resistance is needed. Earlier works[5] suggested that at a given..., there were no reports about the oxidation of the codeposited Ni-SiC nanocomposite coating at high temperature. In the present work, the oxidation performance of Ni-SiC nanocomposite coatings and pure......
; high temperature oxidation 1 Introduction Nickel-based alloys are used widely in aerospace, energy generation and corrosion protection, especially in corrosive environments at high temperatures[1-2... alloys are under consideration as a potential system for hard chromium replacement and high-temperature conductive materials. Therefore, it is very significant to study their high temperature oxidation......
J. Cent. South Univ. Technol. (2008) 15(s1): 135-139 DOI: 10.1007/s11771-008-332-0 Experimental evaluation on high temperature rheological properties of various fiber modified asphalt binders...: High temperature rheological properties of fiber modified asphalt binders and impact of the type and content on such properties were studied. Three types of fiber, including polyester (PET......
. It is important to study the high-temperature oxidation resistance of SC superalloys because of their actual working environments. In a previous paper, WU and NARITA[12] have studied the effect...[J]. Surf Coat Technol, 2007, 202: 140-145. [13] WEINBRUCH S, ANASTASSIADIS A, ORTNER M, MARTINZ H P, WILHARTITZ P.
