Contact resistivity and current flow path at metal/graphene contact [PDF]
Applied Physics Letters, 2010 The contact properties between metal and graphene were examined. The electrical measurement on a multiprobe device with different contact areas revealed that the current flow preferentially entered graphene at the edge of the contact metal. The analysis using the cross-bridge Kelvin (CBK) structure suggested that a transition from the edge conduction ...

Analysis of initial crack path in fretting fatigue [PDF]
Fracture and Structural Integrity, 2016 The initial crack path is analysed in a fretting fatigue test with cylindrical contact, where there is a stress gradient and a multiaxial and non-proportional stress state. For this, a cylindrical pad is pressed, with a constant normal load, N, against a

Comparative Rolling Contact Behavior of Two APS Coatings with Different Matrix [PDF]
Archives of Metallurgy and Materials, 2022 In this study we analyzed the rolling contact fatigue behavior of two types of coatings made by thermal coating, by the method of atmospheric plasma spraying (APS) from two commercially available powders: Ni5Al5Mo and Al2O3 – 13 TiO2. The contact fatigue
