The wear behaviour between coatings with uncoated particles and sol-gel silica coated ones heat treated at 500 °C and 725 °C have been compared. The sprayed coatings with silica coated particles are more homogenous and less porous due to increase of wettability by molten aluminium that takes place on coated particles. The microstructure of the sprayed coatings, the wear surfaces and the wear debris have been anlysed using optical microscopy, scanning electron microscopy and microanalysis techniques (EDX). The results show a smaller wear rate, a lower friction coefficient and more reduced loss of mass for the coatings sprayed with particles with sol-gel silica coatings than those made with uncoated particles.}, number={5}, journal={Revista de Metalurgia}, author={Campo, M. and Escalera, M.
