摘要： An external part of a timepiece has a substrate that includes a base layer and a surface layer, the surface layer including Ti or stainless steel; and a coating disposed on the substrate. The coating includes an outermost layer formed primarily of TiC defining an external surface, and an interior layer formed primarily of TiC positioned between the substrate and the outermost layer. An elastic modulus of the interior layer is greater than the elasticmodulus of the outermost layer.

摘要： A decorative article has a substrate of which at least part of the surface is configured with Ti or stainless steel; and a coating made of primarily TiC and disposed on the substrate. The coating has at least a first region, and a second region disposed closer to the substrate than the first region. The elastic modulus of the second region is greater than the elastic modulus of the first region.

摘要： A decorative article comprises a substrate being primarily composed of at least any of Ti and stainless steel in at least part of a surface vicinity thereof; a first coat being formed on the substrate and being primarily composed of TiCN; a second coat being formed on a side of the first coat opposite a side facing the substrate and being composed of stainless steel; wherein a combined C content ratio and N content ratio in the first coat is equal to or more than 2.0 wt % and less than or equal to 19 wt %.
