With some metals, however, the oxide can continue to grow; for example, Fe2 O3 continues to grow in a humid air environment. 3 Physisorbed Layer Besides the chemically reacted layer that forms on metals in reactive environments, adsorbed layers may be formed from the environment both on metallic or nonmetallic surfaces. For example, the admission of an inert gas, such as argon or krypton, to the surface can produce the physical adsorption of the argon to the clean surface. The most common constituents of adsorbate layers are molecules of water vapor, oxygen, or hydrocarbons from the environment that may be condensed and become physically adsorbed to the solid surface (Haltner, 1969).

29) The measure of how quickly the random event decays is called the correlation length. The correlation length is the length over which the autocorrelation function drops to a small fraction of its value at the origin, typically 10% of its original value. 15. Sometimes, correlation length is defined as the distance at which value of the autocorrelation function is 1/e, that is 37%, which is equal to β for exponential ACF. The correlation length can be taken as that at which two points on a function have just reached the condition where they can be regarded as being independent.

Whether the surface height distribution is isotropic or anisotropic and Gaussian or non-Gaussian depends upon the nature of the processing method. Surfaces that are formed by so called cumulative processes (such as peening, electropolishing and lapping) in which the final shape of each region is the cumulative result of a large number of random discrete local events and irrespective of the distribution governing each individual event, will produce a cumulative effect that is governed by the Gaussian form; it is a direct consequence of the central limit theorem of statistical theory.
