the Radioactive methods of measurement of deterioration

Radioactivity of substances can be used also for measurement of deterioration of surfaces. The way of measurement consists in activating one or both rubbing components tribosoprjazhenija, and the information on deterioration to gain several methods.

In the first case not activated surface which has undergone to deterioration because of contact activated, can be mustered about activity. In the second case the information on deterioration can be gained by measurement of quantity of active materials in greasing eventually. The detailed description of methods is resulted in sources [122]. The system Diagrammatic representation is presented in drawing 1.31.

The radio isotope method of measurement of deterioration has not gained the big popularity by test cars and trainers as has a number of deficiencies. In - first, special precautions should be observed, secondly, was possiblly pollution of the test car and a circumambient, thirdly, sometimes it is impossible to gain the isotopes having the matching periods of disintegration. Besides procedure of activation of components can change their character of a friction, and consequently, and behaviour of deterioration that is especially important at measurement of deterioration of plastic.

Drawing 1.32 - the Principle of act of activation of iron

The deficiency on a radiation level is overcome by a method of activation of a thin layer. In drawing 1.32 the schematic principle of act of activation of iron or a steel [135, 139] is resulted. The thickness of a layer usually makes from 50 to 300 microns, but reception and more thin ( 1000 microns) layers is is possible. This method approaches for metals, composites and plastic. The activated area usually makes nearby 3 мм2, but can be equal and 5 мм2 if it is necessary. The observed method is perspectiv enough for

Deterioration measurements by test cars and simulators, but its deficiency is possible toksikatsija components which is undesirable.
