Developing Ti-Al-Ta-N based coatings: Thermal stability, oxidation resistance, machining performance and adaptive behavior under extreme tribological conditions

Application of hard coatings was found to be a promising method in response to industry’s growing demand for improved productivity and avoiding high temperature in cutting zone. This study presents comprehensive investigations on the effect of Ta addition into TiAlN coating on mechanical properties, oxidation resistance, thermal stability, and ultra-high speed machining performance. The thermal stability of the coatings was studied using DSC, …
