Gonzalo Garcia-Atance Fatjo is a lecturer in engineering at the University of Central Lancashire. Previously, he worked as a design engineer in Madrid and he was involved in the detail design of the high speed train Talgo 350 and airliner Airbus A380. He was a teacher in a vocational school in an indigenous village in Guatemala. He is an aeronautical engineer from the Polytechnic University of Madrid and did his PhD in cavitation erosion of ceramics.
Gonzalo Garcia-Atance Fatjo finished his PhD in Tribology in 2010. His PhD research was focused on the erosion of technical ceramic due to cavitation where he found out a delay in the phase transformation of metastable zirconia and made a contribution in the understanding of the erosion mechanism in ceramics. Also, he developed a mathematical model to explain the location of cavitation clusters within the liquid by combining Analytical Mechanics Principles with Fluid Mechanics. Previous to his PhD, he conducted a short research project funded by SKF Research & Development Co. to assess the performance of ceramics materials used in bearings subjected to cavitation erosion. He has been involved in research of lubrication monitoring and lubricant testing. He is currently conducting research at UCLAN in piston engines. His goal is to improve the understanding of the lubrication of the ring pack.
In 2001 and from 2004 until 2007, Gonzalo was an international aid worker in Guatemala, where he taught technical drawings and building design. He was responsible for the implementation of computer based design in the new curriculum for the Instituto Tecnologico k’iche’. Also he designed a 800 m2 building with classrooms and workshops for the Instituto and was involved in numerous international aid projects.
Gonzalo has also working experience in the industry. He worked as a consultant design engineer for Altran Technologies in Madrid where he did the detail design of a bogie with change of railway width, russo-european, for Talgo; and the design of a beam and a bulkhead for the airplane Airbus A380, among others.

Erosion and wear of ceramics materials. Ceramics are composed by crystalline grains and glassy intergranular phase. The intergranular phase prevents the material from deforming and produces a brittle behaviour. The interaction of the grains with the intergranular phase and the stresses applied is a key factor to understand the wear and erosion of ceramics. Furthermore, zirconia has a metastable phase that transforms into stable under the tension stress that occurs in the erosion and wear of zirconia.
Cavitation erosion and cavitation phenomena in liquids. Cavitation in Fluid Mechanics is the change of phase from liquid to vapour due to a local low pressure. This creates vapour bubbles that may collapse violently when the pressure returns to its normal value. The location of cavitation clusters in ultrasonic cavitation has been explained by Gonzalo using Hamilton’s principle.
Tribology is a multidisciplinary discipline that studies the wear and friction of mechanical parts and its lubrication and is highly experimental. Gonzalo has helped to develop a model to predict friction in a pin on disc configuration test bench. Also, he has participated in a research that suggests a modification of the standard test (ASTM D4172) with the measurement of volume with an interferometer or a confocal microscope instead of using only an optical microscope. Gonzalo has looked into the wear mechanism of abrasion in metal and ceramic tribological pairs.
Piston engines are a type of engine that it is widely spread worldwide in numerous daily life and transport applications. The ring pack and its interaction with the liner are a key factor to improve efficiency, working life and reduce CO2 emissions. The lubrication of the ring pack is studied by the installation of sensors in an operating engine. The result of this research is expected to improve future designs of piston engines.
