Multilayered carbon films for tribological applications

摘要: Recent work has shown that for nano-layered structures consisting of two materials, an effect may be in which the elastic modulus and fracture toughness depend on period structure. In this paper we create carbon multilayer by methods using cathodic arc deposition with pulsed bias applied to substrate. The multilayers are created one class simply interrupting form relaxed layers. other structures, pulse conditions varied periodically. in-service performance is assessed impact-enhanced pin-on-disc wear testing indentation hardness. examined bright field dark transmission electron microscopy. A 10 nm non-convergent probe was used micro-diffraction studies. model structure interfaces between layers as-deposited material, including evidence preferred orientation presented.
