    Abstract: In this study we are interested in gear degradation under solid pollution effect. With this intention, An experiment which simulates operation of gears loaded in polluted media was carried out. The study tries to answer questions in relationship with the presence effect of solid particles in lubricants on surfaces contact. We show that the use of a lubricant polluted by very fine sand particles, leads to notable wear at first operations cycles. The pollutant presence in the first hand, increases friction, therefore rises the temperature and on the other hand, leads to a bad quality of surfaces.
