Abstract
A method of forming a wear-resistant coating on an article includes depositing a chromium coating on a substrate of the article, and subsequently heating the coated article to enhance a plurality of through-cracks within the chromium coating. The method further includes applying a liquid filler material to the coated article such that at least one of the plurality of through-cracks is at least partially occupied by the filler material, and solidifying the liquid filler material
