A comparative study in the tribological behavior of DLC coatings deposited by HiPIMS technology with positive pulses

During the last few decades, diamond-like carbon (DLC) coatings were widely used for tribological applications, being an effective tool for improving the performance and the useful life of different machining tools. Despite its excellent properties, among which stand out a high hardness, a very low...
