PREFACE
Over the last forty years a wide range of surface coatings have been developed to
address the surface stability andthermal insulation ofmaterials used inthe gasturbine
section of aero, industrial and land-based power generation equipment. High Tem-
perature Surface Engineering reviews the surfacing technologies appropriate to oxi-
dation, corrosion and thermal protection. Factors which underpin their choice for any
given application arediscussed in theproceedings. This highlights the importance of
developing representative mechanical and physical test methods to elucidate coating
degradation modes asan aid to establishing coating systems with improved engineer-
ing performance.
During the organisation of the conference and in the compiling of this book we
have been privileged to work with many ofthe leading specialists in the field ofHigh
Temperature Surface Engineering and it is our hope that this book will be avaluable
reference guide for Engineers and Material Scientists.
