CA 2564428

A coated article is provided that may be heat treated in certain example embodiments. A grader layer (e.g., contact layer or other suitable layer) is formed by initially sputter-depositing a layer, and thereafter ion beam treating the sputter-deposited layer with at least reactive gas ions in order to form a graded layer. In certain example embodiments, the result is a coated article that has improved visible transmission and/or durability, without sacrificing optional heat treatability.

La présente invention se rapporte à un objet revêtu, qui peut faire l'objet d'un traitement thermique dans certains modes de réalisation exemplaires. Une couche graduée (par ex., une couche de contact ou une autre couche appropriée) est formée par la pulvérisation cathodique initiale d'une couche, puis par traitement ionique de ladite couche à l'aide d'au moins des ions de gaz réactif afin de former une couche graduée. Dans certains modes de réalisation exemplaires, l'on obtient un objet revêtu présentant une transmission de la lumière visible et/ou une durabilité améliorées, et ce sans que l'aptitude au traitement thermique ne soit sacrifiée.
