Abstract

This article discusses two approaches for determining gaseous corrosion rates, one based on indirect (discontinuous) measurements, the other based on direct (continuous) measurements. It explains how corrosion rate data can be obtained indirectly by measuring scale thickness, scale weight per unit surface area, loss of metal thickness, loss of material weight per unit surface area, or weight change of oxidant bonded in the scale per unit surface area as a function of time. It also describes several continuous methods, including volumetric measurements, the manometric method, and thermogravimetric analysis, and the conditions under which they can be used.
