Investigation of sliding properties of selected plastics and greases applied for elements of winter sport equipment

摘要

The article presents the results of friction coefficient measurements of selected polymer materials applied for elements of winter sports equipment sliding against ice. After testing, one of the materials, polyethylene, which is the most commonly used material for ski slides, was selected and tested again, this time, in the presence of various types of ski lubricants. The research was carried out on a pin-on-disc tester placed in a climatic chamber. Obtained results revealed that the selection of the lubricant is a matter of great importance to the reduction of the frictional resistance and should be strictly conditioned by the ambient temperature and associated prevailing snow conditions.
