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.
