[en] Radiographic stress measurement is a general method for determining both load and internal stresses. The principles and possible applications of radiographic stress measurement are described. Also discussed are possible ways of diagnosing previous surface stressing by means of radiographic stress measurement. (author)

[en] Some molybdenum complexes were synthesized and described especially with respect to both friction and wear reduction. The use of these substances is discussed with due consideration of the influence of higher temperatures and the increase in critical load. Complexes containing a maximum number of sulfur atoms proved to be most effective. (author)

[en] Variants of activation and measurement are presented. An application example - radiometric wear measurement of refrigerant compressors - is given, and an improved version of the method, a two-nuclide technique used for measurements with wear debris losses, is described. The radiometric method of wear measurement can still be developed further and extended to include additional applications. (author)

[en] The wear behavior of metallic materials can be substantially improved by implantation with high energy ions. Compared to conventional methods for wear reduction, ion implantation involves a number of important advantages. However, the method is still in its infancy, with high system costs presently limiting its use to specialty tools. (author)

[en] A fast testing method and apparatus for determining lubricating oil, frictional, and wearing properties by means of radioactively labeled sliding pairs are presented. Model equations used to calculate rates of wear and determine oil film thicknesses are formulated. (author)

[en] Wear-resisting surface layers showing excellent adhesion to steel can be produced by ion beam-induced admixing as well as by implantation-assisted coating. The influence on the substrate of the ion beam beyond the region of the top coating results in the wear-inhibiting characteristics being retained even after attrition of the layer of hard material.
