CA 2504541

A coated article is provided with a coating or layer system that includes at least one layer including zirconium (ZR) and/or zirconium nitride (ZrNx) sandwiched between at least a pair of dielectric layers. In certain example embodiments, the coating or layer system has good corrosion resistance, good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ~.DELTA.E* value (s) upon heat treatment (HT).

L'invention concerne un article revêtu comprenant un revêtement ou un système de couche qui contient au moins une couche contenant du zirconium (ZR) et/ou du nitrure de zirconium (ZrN¿x?) pris en sandwich entre au moins une paire de couches diélectriques. Dans certains modes de réalisation représentatifs, le revêtement ou le système de couche présente une bonne résistance à la corrosion, une bonne performance mécanique telle que la résistance aux rayures, et/ou une bonne stabilité à la couleur (i.e., une/des faible(s) valeur(s) ?E*) lors du traitement thermique (HT).
