Greases are widely used in machinery and automotive components to protect components from frictional and wear losses. As a result, interaction properties like adhesion to the substrate, cohesion or consistency, and tackiness become crucial factors an

In order to characterize the wear and related mechanical behavior of materials from small volumes, a program employing nanoscratch and nanoindentation was performed. Nanoscratch techniques were used to generate square wear patterns with varying degre

The role of substrate plasticity on the tribological behavior of diamond-like nanocomposite coatings
Publikováno v:
Acta Materialia. 56:1956-1966
Finite-element modeling (FEM) was used to predict the contact stress at which the transition from elastic to plastic deformation occurs in a metallic substrate underneath a hard tribological coating. Using model systems of diamond-like nanocomposite

The fracture behavior and toughness of thin tetrahedral amorphous carbon (ta-C) films were examined using acoustic-sensing nanoindentation. Laser annealing was used to induce several levels of film stress ranging from −1.7 GPa (compressive) to +2.4

Understanding the hardening response of small volumes is necessary to completely explain the mechanical properties of thin films and nanostructures. This experimental study deals with the deformation and hardening response in gold and copper films ra

A study of ultra-thin gold films and thin-walled nanoboxes has confirmed that length scales in terms of dislocation spacing can predict flow stress. Initial stages of deformation conform to linear hardening with average dislocation spacing controlled

Length scales are essential to the understanding of small volume deformation and fracture in emerging technologies. Recent analysis by two groups at the atomistic (Horstmeyer and Baskes, 1999) and mesoscopic (Gerberich et al., 2002) levels have shown

Fracture and contact mechanics can synergistically contribute to the fundamental understanding essential to scaling of small volumes. Consider two levels of scale in terms of contact area: (i) light wear of tribological contacts at the nanometre leve
