Abstract: The increasing development of the petroleum industry has required new technologies in the production of materials that resist the corrosive environments such as storage and transportation of crude oil. Accordingly, the ceramic materials that are highly resistant to hostile environments have great potential for such applications. As ceramic materials are fragile, in this work we have produced alumina-titania based ceramic composites having high brittle toughness and high mechanical strength.
Alumina-titania ceramic composites added with 1-3% ceria were produced through thermo-mechanical processing and normal sintering techniques.structural, microstructural characterizations and mechanical tests were carried out to evaluate the use of these composites in the manufacture of crude petroleum oil storage tanks made of metallic matrix coated with the composites ceramics developed in this work. The results will be presented and discussed in this paper.

1. INTRODUCTION
The crude petroleum is a highly corrosive material so there is considerable degradation of surface of the tanks for storage and transportation of crude oil, which is made of metallic materials, is a serious problem in the petroleum extraction industry. Thus, an alternative to solve this problem is to use a type of coating inert to such corrosion. Ceramics usually have this characteristic and may be a choice of material for this coating. In the high technology industries ceramic materials
