Abstract

Le problème décrit par la présente invention est de réaliser un élément décoratif qui produit un éclat noirâtre dérivé de métal tout en démontrant une résistance supérieure à l'usure et en possédant un poids réduit. La solution selon l'invention consiste à réaliser les deux caractéristiques de résistance à l'usure et poids réduit en appliquant, sur un élément décoratif, un cermet constitué d'une phase dure comprenant au moins deux composés parmi TiCN, TiC, TiN, et MoC2 dans une proportion de 70 à 97 % en masse, le reste étant constitué d'une phase de liant et des impuretés inévitables. Il est également possible de réaliser un élément décoratif simple d'utilisation qui satisfait toutes les caractéristiques de résistance à l'usure, de poids réduit, et d'éclat métallique noirâtre en finissant la rugosité de surface de l'élément décoratif à un état de finition de miroir.
