ADHESION OF COMPOSITE MATERIALS

The nano-scratching studies the adhesion between the deposition of the composite material and substrate and provides details about the friction coefficient, depth of penetrating etc. The nanoscratching tests involving the movement of an indent, with constant speed, on a composite layer surface, driven by increasing normal force denoted L (load). For metal matrix composite layer of nickel-phosphorous with silicon carbide incorporated particles was obtained, after the nanoscratching test, a friction coefficient which has a nearly constant value of 0.35.
