Abstract

Some mechanical and tribological properties of electroless Ni-P/ diamond composite films are measured, modelled by the finite element method and discussed. Preparation methods are briefly sketched. Hardness, Young's modulus and Milman's plasticity parameter are evaluated by diamond pyramid indentation methods; sliding wear behaviour is tested with the pin-on-disk technique. The application of the correlations for indentation testing is treated statistically in view of a quantitative use. The variations of mechanical properties induced by the dispersion of ceramic particles are quantitatively correlated with structural characteristics of the composite films.
