High temperature oxidation resistance behavior of Ti3SiC2/Cu composites under migration of Ti and Cu atomic
The oxidation behavior and oxidation mechanism of Ti3SiC2/Cu composites were investigated using constant temperature oxidation method. The Ti3SiC2/Cu composites were prepared at different sintering temperatures. Results showed that the relationship between the oxidation reaction rate of Ti3SiC2/Cu composites in air at 700 °C–900 °C and the oxidation temperature was in accordance with the parabolic law of oxidation kinetics. The oxidation weight gain and oxide layer thickness of Ti3SiC2/Cu composites at 700 °C and 800 °C were insignificant, with oxidation reaction rates of 3.0692 × 10−9 kg2m−4h−1 and 6.9856 × 10−9 kg2m−4h−1, respectively, and the oxidation rate of Ti3SiC2/Cu composites at 900 °C was enhanced to 1.00907 × 10−8 kg2m−4h−1. Ti3SiC2/Cu composites oxidized at 900 °C formed a protective oxide layer, which was mainly a multilayer structure composed of different kinds of oxides: the outer layer was mainly composed of TiO2; the intermediate layer mainly consisted of CuO; the inner layer mainly made up of TiO2 and SiO2.
期刊介绍：
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
