CA 2657373
In certain example embodiments, a coated article includes a Zn-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the Zn-doped zirconium based layer to transform into a Zn-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with Zn has been found to improve scratch resistance and/or corrosion resistance.
La présente invention concerne, dans certains modes de réalisation, un article revêtu comprenant une couche à base de zirconium dopé au zinc avant le traitement thermique (HT). L'article revêtu subit un traitement thermique suffisant pour que la couche à base de zirconium dopé au zinc se transforme en une couche à base d'oxyde de zirconium dopé au zinc qui est résistante aux rayures et/ou chimiquement durable. Il a été constaté que le dopage de la couche avec du zinc améliorait la résistance aux rayures et/ou la résistance à la corrosion.
