Abstract
In the petroleum industry it is necessary to store and transport crude oil, which is done by means of metallic materials tanks. Crude oil is a corrosive product and surface degradation of these tanks is serious problem for the oil industry. In this way, we found alternative solution to the issue is to use inert coating and corrosion that ceramic materials are in favor such as shielding materials, for support, more efficiently, the corrosion process. ZrO2 have mechanical properties superior to other ceramic oxides and refined microstructure, TZP, further elevates its properties. Studies have reported that TiO2 with earth oxides are sources of TZP materials with improved properties, such as toughness. This work aims to produce ceramic composites from zirconium oxide and titanium, the ZrO2-TiO2 type, for thermomechanical process, with variations from 5% to 20% TiO2 (by weight) of zirconia and reinforced with Y2O3. Then, the composites undergo milling process for 24 hours and cold pressing to be then sintered at a temperature of 1200 ºC 1700 ºC. Subsequently go through microstructural analysis, structural, chemical and mechanical. They will be tested in a hostile environment of crude oil and then their properties will be reassessed to observe the behavior of ceramic composites.
