Abstract in another language

Solving tribological problems means usage of lubricants e.g. grease or oil which normally are harmful for the environment. Thin film coatings with PVD solid lubricant films can help to solve the tribological problem on one side and enable us Design for Environment on the other. Some characteristics of machine elements, which have interacting surfaces standing in relative motion, have impacts on the environment on the one hand and extensive life cycle consequences on the other hand. A competent knowledge of the effects of wear and friction between these interacting surfaces as well as the knowledge on the effect of lubrication is a prerequisite for the function, quality and cost of many products in our life. This knowledge is the pre-condition of the realisation of products with tribological elements with excellent properties in both fields. For a holistic optimisation it is very important to emphasis fundamental considerations in the early stages of a methodical product design process and to manufacture appropriate tribological systems by election of environmental friendly technologies. In use of products with tribological construction elements there are different environmental consequences. For example lubrication has to be used to guarantee functionality, but leaking lubrication into the environment could cause the pollution of ground water. For the recycling of such parts the used lubrication materials must be removed in expendably and partly difficult processes.
An appropriate technology which could help to avoid or reduce these environmental problems in the whole lifecycle is the thin-film-technology by use of the PVD-process (Physical-Vapour-Deposition). It is a non-polluting method for producing thin films (100nm up to 5 µm) on high precision mechanical parts with rolling/sliding contact, in order to retain reliability. Different coating systems e.g. low-friction for wear protection or soft solid lubricant films can be created. Thin-film-technology avoid using of toxic materials (e.g. carbon or molybdenum disulphide) as lubricants and no additional steps or special processes for recycling are necessary.
Examples for solid lubricated mechanical parts are deep groove ball bearings for x-ray tubes, uniball bearings and linear guidance systems which are briefly presented.
