Application of RNB for high sensitive wear diagnostics in medicine technique and industry

A compact fretting device for testing of biomaterials by means of thin layer activation

“…The method is based on the fact that the activity loss of the activated sample can be correlated to the amount of sample material released in the experiment. As an accelerator-based technique, reports of the use of thin layer activation in tribological studies of biomaterials are rare, but it has been demonstrated to be applicable to investigate the wear of articulating parts in artificial joints [20,21]. Lodges et al [22] used thin layer activation to measure the fretting wear of Ti-6Al-4V on Ti-6Al-4V in air.…”

Gamma-ray inspection of rotating object

“…For example, the flow and mixing of fluids like gas, liquid or powder are measured in petroleum, chemical and mineral-processing industries [2,3], where radiotracers are injected to the fluid and monitored at downstream by radiation detectors. On the other hand, thin-layer activation (TLA) method is employed for diagnosis of wear or corrosion of solid materials of machine parts or piping, where a thin layer of the surface of the object is activated and the removal rate of the surface is determined by the measurement of the radioactivity [4,5].…”

Wear measurement of highly cross‐linked UHMWPE using a 7Be tracer implantation technique

“…In related tribological fields, such as mechanical engineering, the radionuclide technique enabled wear and corrosion diagnostics of vital parts during machine operation. In one of the available methods, the so‐called “thin layer activation” (TLA), the decrease of the radioactive layer during the wear process is measured using a gamma ray detector outside the machine 12…”

“…In one of the available methods, the so-called ''thin layer activation'' (TLA), the decrease of the radioactive layer during the wear process is measured using a gamma ray detector outside the machine. 12 Radioactive thin-layer labeling of metallic and ceramic machine parts is usually achieved via nuclear reactions of fast charged particles (e.g., protons) in the solid material. However, for plastics this activation method becomes highly inefficient.…”
