Definitions
- the present invention relates to a ski edge profile made of steel and a ski with a ski edge profile.
- a ski has a base body, which mostly consists of plastic and generally has a structure of several layers, which can be glass fiber or carbon fiber reinforced in order to achieve defined elasticity and damping properties.
- the side ski edges of the tread which are subject to particularly high loads, are formed by steel ski edge profiles. This is an essentially L-shaped profile, which with a
- the profile head which is usually ground at right angles, extends along the particularly stressed tread edge.
- ski edge profiles made of steel, preferably hardened
- ski edge is described for example in DE 297 05 070 U 1.
- ski edges which consist of hardenable steel alloys, have outstanding properties, particularly with regard to durability and wear resistance.
- the object of the invention is to provide a ski edge profile which brings a further improvement in the sliding properties of a ski provided with such ski edge profiles, in particular under extreme stresses such as occur in ski racing.
- the ski edge profile consists of a steel alloy with a relatively low thermal conductivity.
- the invention is based on the surprising finding that a further significant improvement in the sliding properties is hardly possible by improving the mechanical material properties of the ski edge, but with regard to the thermal properties, one that has not yet been used
- the approach according to the invention specifically provides that steel alloys are used in particular which, due to their alloy additives, have a lower thermal conductivity than the hardenable carbon steels used hitherto.
- Heat dissipation ensures that a better sliding film is created between the edge of the ski and the ski surface (through local, brief melting), which improves the sliding properties, so that the ski runs faster.
- the hardness, wear resistance, shape accuracy and the edge retention of the ski edge made of steel is not adversely affected.
- a steel alloy with an increased proportion of such alloy elements is used which lower the thermal conductivity.
- This can be an addition of silicon, for example.
- the silicon content can be approximately between 0.3% and 3.0% based on the melt analysis, preferably between 0.5% and 2.5%.
- Silicon-alloyed carbon steels are particularly well suited to realizing the invention, in the range with proportions of 0.5% -0.8% carbon and 1.2% -2.3% silicon (in% by weight).
- the table below shows the chemical analysis and typical values of the chemical analysis, density and thermal conductivity ⁇ , namely for an alloy 1 used in the prior art for producing ski edges and for an alloy 2 according to the invention:
