Abstract
The Petroleum and its derivatives are extremely import to a modern society [1]; however, the peculiar characteristics of petroleum, such as corrosive and chemically reactive character, give rise to hostile environments. With this comes the need to find materials that are able to resist severe environments. One way of solving the problem of surface degradation is the use of ceramic materials based on alumina as an inert coating to hostile environments by the hypersonic thermal spray coating (HVOF) process. With the coating application, it is possible to avoid the process of corrosion and wear of transport and storage tanks of petroleum,. In the present work were produced ceramic composites based on Al2O3-TiO2 reinforced with CeO2 in proportions of 10-20% by weight of TiO2 and, 5% and 7% by weight of CeO2 and studied as structural, microstructural and mechanical properties. We produced these composites by a thermomechanical process, sintered at 1350°C, analysed by scanning electron microscopy and Vickers microhardness. The results of this study are analysed, discussed in this paper.
