The present paper deals with a theoretical and experimental study of the co‐deposition of spheroidal particles in a metal matrix deposited by autocatalytic chemical deposition (ACD). The 3‐D particle size distribution — as measured by image analysis of SEM micrographs of metallographic cross‐sections — is related to the size distribution of the starting powder — as measured by photon autocorrelation spectroscopy — through a simple analytical model. The application of the model to the co‐deposition of diamond particles in an ACD Ni–P (9 wt.% P) amorphous matrix led to a correct prediction of average volume of embedded particles ( V ¯), coverage factor ( C F ) and number of co‐deposited particles per unit volume of deposit ( N V ).
