The thin layer activation technique (TLA) is very effective in wear analysis for tribological systems where disassembly is costly or impractical. Since its development in the 1970s, TLA has been applied through direct irradiation of solid targets using ionizing particle beams to obtain an activation with a specific profile. This profile is then used to measure wear in a variety of experiments. These experiments rely heavily on how deep the normalized activation occurs. Depths of 30μm to 50μm are obtained for constant activation by the standard method, which for many experiments is sufficient. How-ever, many others would benefit greatly from a 300μm constant activation layer, such as high-performance engi-nes, softer alloys (brakes), and oil transport systems. Achieving this aim was the goal of this paper. First, we needed to find an adequate irradiation line for the TLA technique. Then, another technique/system was developed (the Attenuation Wheel), which would bring the depth of constant activation from 50μm to 300μm.
