In this first chapter on tribology the key word will be surface. This chapter will be rather ambitious in scope in that we will attempt to cover the range from microscopic to macroscopic. We will approach this problem in steps first considering the fundamental idea of a surface next recognizing its atomic character and the expectations of a ball model of the atomic structures present. We will then consider more realistic relaxed surfaces and then consider how the class of surface . metal semiconductor or insulator affects these considerations. Finally we will present what is expected when a pure material is alloyed and the effects of adsorbates. Following these more fundamental descriptions we will give brief descriptions of some of the experimental techniques used to determine surface properties and their limitations. The primary objective here will be to provide a source for more thorough examination by the interested reader. Finally we will examine the relationship of tribological experiments to these more .
