A process of applying a coating to a substrate is provided. A layer of a ceramic material is applied on the substrate by a thermal spray process. The layer is then subject to plasma electrolytic oxidation (PEO) processing to densify the layer such that a porosity of the layer after PEO processing is lower than a porosity of the layer before PEO processing, or modify the layer by incorporating additional ceramic phases from the electrolyte bath into the densified layer, or improve the adhesion of the thermal spray layer. A base layer may be applied to the substrate with PEO processing before the above referenced layer is applied and/or a ceramic topcoat may be applied to the above referenced layer by a thermal spray process.

The present invention relates to a sports boot (1; 1'), of the type comprising a shell (3; 3') and a cuff (5; 5') both made of a substantially rigid plastic material, and having a tightening system (10) for tightening said shell and said cuff onto the user's foot and ankle, or releasing said shell and said cuff from the user's foot and ankle. According to the invention, said tightening system (10) comprises one or more traction cables (11; 11a, 11b), first guide elements (13) arranged at the shell, second guide elements (15) arranged at the cuff, and a single tensioning mechanism (17) suitable to control the tensioning or releasing of said one or more traction cables. Thanks to the provision of a single tensioning mechanism, the user can advantageously act on a single actuating device to simultaneously tighten or release both the shell and the cuff of the boot according to the invention.

A modular electrical connection system (100) for two/three-dimensional lighting is described, comprising a plurality of two-dimensional modules (10), each module (10) comprising two distinct polarities (11, 12) connectable to an electrical supply, a negative pole (11) and a positive pole (12), each pole (11, 12) being formed by a bar of electrically conductive material connected to a light source (50) by means of an elastic element (40), each pole (11, 12) connected to a structural element (21, 22) formed by a bar of electrically conductive material by means of an elastic element (40).

The present invention relates to a tightening system (9) for a sports footwear comprising one or more traction elements (13, 21) that are guided in succession through a tortuous path by guide elements (15a, 15b, 17a, 17b, 23a,23b, 25a, 25b) fixed to said sports footwear and that can be tensioned or released by corresponding actuating elements (11, 19). According to the invention, said tightening system (9) comprises at least a restraining element (27) suitable to limit two or more adjacent exposed portions of traction element from displacing relative to each other, thereby reducing the risk of said cable portions interfering with other elements of the sports footwear (1) when said traction elements (13, 21) are released.
