Abstract
The article presents a new approach to solve the problem of reducing the friction force when the sliding surfaces of sports apparatuses interact with ice. The qualitative analysis of major factors impacting on the resistance to sliding of blades and sledge runners is given, the algorithm of further minimization of deformation and molecular components of the friction force is offered. Also technical characteristics of surfaces of real sports apparatuses are cited and the methods of their additional processing based on the analogy with natural surfaces at minimal adhesion with water are offered. The impact of physical and chemical properties of a liquid film in the zone of the contact of a skate with ice as a factor of an adhesion component of friction is grounded. The possibilities of modern laser technologies in the field of formation of an artificial structure at “double roughness” on sliding surfaces of blades identical to the structure of the lotus leaf are described. The results of experimental studies of sliding properties of blades with different types of additional processing are presented. The results confirm the advantages of the structure at “double roughness” to reduce the total resistance force to sliding. Keywords: structure at “double roughness”, laser processing, sliding friction, lotus effect
