| Abstract Scope |
Molybdenum Disulfide thin films are the premiere solid lubricant for aerospace and hermetic applications. Their process-structure-property relationships can be seen as somewhat straightforward, with consensus over the years pointing to basal texture and high density being most desirable for reducing friction and wear. Regardless, an understanding of deposition processes resulting in highly dense, crystalline structures is lacking, with even less evidence linking structure to tribological and mechanical performance. Collocation of deposition and tribological testing in a high throughput testing/deposition feedback loop has greatly helped to optimize deposition of MoS2 films based on functional metrics like hardness and wear rate of MoS2 that directly relate to the density and structure of the films. This work also demonstrates how these “functional metrics” can help guide deposition of films and aid in predicting their susceptibility to degradation in accelerated aging environments. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
