摘要：A method for forming a chromium nitride coating over a substrate to provide a chromium nitride coated article, and the resulting chromium nitride coated article, each use a bilayer chromium nitride containing material layer. The bilayer chromium nitride containing material layer includes: (1) a first chromium nitride material layer having a first thickness, a first uniform chromium concentration and a first uniform nitrogen concentration located and formed closer to a substrate which provides the article; and (2) a second chromium nitride material layer having a second thickness, a second increasingly graded chromium concentration and a second decreasingly graded nitrogen concentration located and formed upon the first chromium nitride material layer. This particular bilayer chromium nitride containing material layer provides the article with superior reflectivity and crack resistance.
