Description

A kind of preparation method of skating boots skates
Technical field
The present invention relates to field of alloy material, in particular to a kind of preparation method of skating boots skates.
Background technology
Skating is using the skating boots with skates as tool, in conjunction with the sports events of personal strength and technology.Skating is made For one of the main project of Winter Olympic Games, the influence factor of competitiveness other than the personal skill of skater, Most important is exactly the performance of skates on skating boots.For example, disconnected to pedaling the transmission capacity of ice power, plasticity_resistant deformation ability, anti-brittleness Split ability and long-time wear-resisting property etc..The physical characteristic and mechanical property of blade are to determine skates in the mechanical realization of skates One of principal element of quality level, this is related to the surface roughness of the hardness and tactile ice face of the integral strength of blade, blade Deng.And the research of high-performance skates is more short of in China, is either commonly skated used in fan or sportsman The high-quality skates overwhelming majority relies on import.Therefore, development of new skating boots skates, the design and producing for realizing skates are autonomous The competitiveness for changing, promoting related event on ices, has important practical significance and strategic importance.
When ice is pedaled in skating, skates blade bears larger stress, slides the blade and ice face high-speed friction of middle skating boots, makes With needing often to bear larger frictional force in the process, skates after a period of use, cutting edge can rust, at this moment usually require It is re-grind, it is made to return to the original form.So the main reason for abrasion of skates is skating boots loss, and can be right Skating produces a very large impact, can be time-consuming and laborious to be continuing in the short time although whetting a knife repeatedly.Therefore, in the prior art The technical issues that need to address are that while allowing skates to have certain rigidity and toughness, have comparable wear-resisting property and smaller Surface roughness.
Invention content
Metal and the respective excellent properties of wear-resistant material are exactly combined and are used by surface-coating technology, metal Intensity is preferable with bearing capacity and wear-resisting property is relatively poor, and some other materials have very high wear-resisting property but carrying energy Power is limited, and face coat improves the overall performance of workpiece exactly by the two in conjunction with respective superiority is played.
