Ti 1−x Al x N coatings with NaCl-type structure have been widely used in advanced machining and other high temperature applications due to their excellent mechanical, thermal and tribological properties. Here, we investigated the influence of Cr additions on the structure, mechanical properties and oxidation resistance, including the oxide scale characterization, of multilayered TiAlN/CrAlN coatings deposited by magnetron sputtering. The properties of Cr rich coatings were compared to a TiAlN film deposited as reference. XRD diffraction analysis revealed that all coatings showed an fcc NaCl-type structure.
Traditional design techniques for FPGAs are based on using hardware description languages, with functional and postplace-and-route simulation as a means to check design correctness and remove detected errors. With large complexity of things to be designed it is necessary to introduce new design approaches that will increase the level of abstraction while maintaining the necessary efficiency of a computation performed in hardware that we are used to today. This paper presents one such methodology that builds upon existing research in multithreading, object composability and encapsulation, partial runtime reconfiguration, and self adaptation. The methodology is based on currently available FPGA design tools. The efficiency of the methodology is evaluated on basic vector and matrix operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
