摘要

Several industrial and laboratory wear studies need a reliable, accurate and sensitive method to determine very small wear amounts quantitatively. Microscopic wear amounts are characteristic for the initial stage of any wear (or corrosion) process and some special wear (or corrosion) processes even never reach a stage of macroscopic wear amounts. A typical example is fretting wear. Most of the classical wear methods fail to measure very small wear amounts in a sensitive and accurate way. The nuclear method based on Thin Layer Activation (TLA) however is able to do so. The fundamentals of TLA are explained in detail in this paper and its application for the determination of fretting wear of unlubricated steel surfaces in laboratory conditions is described. Typical fretting wear results obtained with TLA are presented and compared with classical spherical cap fretting wear modelling results.
