Microstructure, mechanical and tribological performance of nanostructured TiAlTaN-(TiAlN/TaN)n coatings: Understanding the effect of quaternary/multilayer volume fraction

Four nanostructured TiAlTaN-(TiAlN/TaN)n coatings were deposited, varying the volume fraction of the top quaternary coating (TiAlTaN) and the base multilayer coating (TiAlN/TaN) with percentages of: 84/16, 66/34, 48/52 and 23/77, and evaluating their effect on mechanical and tribological performance...
