Problems solved by technology

[0007] In addition, the current mechanical processing and sharpening technology has made the blade of ice skates have an extremely smooth surface, and its surface roughness Ra<1.6μm. The existing surface modification treatment methods can reduce the surface roughness to a small extent. The actual drag reduction effect is very limited
[0008] Based on the above reasons, there is currently no drag reduction technology that has a significant drag reduction effect and can be engineered to be applied to ice skates to effectively reduce its frictional resistance.

Abstract

The invention provides a novel ice skate blade drag reduction technology and an implementation method thereof, aiming at the dynamic characteristics and technical status of skating sports equipment. According to the novel ice skate blade drag reduction technology and the implementation method, through surface modification treatment on an ice skate blade substrate, the heat conductivity coefficientof an ice skate blade and heat loss caused by friction heat conduction to the ice skate blade substrate are obviously reduced, the heat flow distribution coefficient of the friction heat conduction to the ice surface is increased, and more friction heat is used for melting the ice surface to increase the thickness of a water lubricating film, so that water-based lubrication drag reduction is realized, the friction coefficient of the ice surface is greatly reduced, and the tribological performance of the ice skate blade is improved. The novel ice skate blade drag reduction technology and the implementation method have the outstanding characteristics of novel technical principle, remarkable drag reduction effect, easiness in engineering realization and the like.

Description

technical field [0001] The invention belongs to the technical field of surface engineering and tribology, and relates to a novel ice blade drag reduction technology and a realization method thereof, which can be used on ice blades of skating sports equipment such as skates and skeletons. Background technique [0002] Ice skating is a sport in which athletes use skates to obtain driving force by kicking the ice and overcome frictional resistance to slide quickly on the ice. As the main equipment of skating, the service process of ice skates is a complex process involving the combined effects of friction, wear and pressure. Once the ice skates have poor surface tribological performance, deformation or wear, it will affect the performance of the athletes' competitive level, and even cause damage to the athletes themselves. Improving the anti-friction and wear-resisting properties of ice skates is of great significance for improving the service characteristics of ice skates and...
