Figure 4

(a) Coefficient of friction measured using pico-scratch on the interface of dendrite and matrix material. A sharp rise in the friction value is seen on the interface as the indenter transitions from dendrite (denoted with D) to matrix (denoted with M). (b) SEM image of the sample and pico-indenter after competition of scratch test. The dendritic phase is discontinuous as highlighted with dash-dot line. The cube corner diamond indenter has retracted to the initial position after traversing the set scratch length. There is no material adhering to the indenter, and the displaced material is ejected out of the wear track, and dislodged at the edge.
