High-temperature oxidation behavior of un-dense Ti3AlC2 material at 1000°C in air
Source abstract
Abstract
Abstract Un-dense Ti 3 AlC 2 material containing 3 wt% TiC was prepared by hot-pressing process using elemental powders of 2TiC/Ti/Al. Its oxidation behavior at 1000 °C in static air was investigated. SEM analysis indicates that the as fabricated sample is un-dense and the Ti 3 AlC 2 grains with plate-like shape exhibit two types of fracture surfaces of layered and flat features. The oxidation behavior of the product exposed at 1000 °C for 30 h obeys a near-cubic law. The scale consists of rutile TiO 2 and α-Al 2 O 3 phases, and presents three layers, including an outer un-dense TiO 2 layer adhering to a little Al 2 O 3 , a thick intermediate TiO 2 + Al 2 O 3 mixed layer and a thin inner Al 2 O 3 layer with some pores. The thickness of the oxide layer was higher than 300 μm. In addition, the deleterious effects of TiC and innate-pores on the oxidation resistance of the product were also investigated.
