Wear of agricultural machines parts in the soil

Abstract EN

Wear intensity of Agricultural machines functional parts in the Soil is influenced by chemical potential of the soil due to interaction of the metal of these parts with chemical solutions in the soil.

The experiment was conducted to study the wear intensity of the metal CK45 in abrasive medium being moistened by 20% solutions of inorganic compounds, mainly an inorganic fertilizers.

Wear intensity in solutions was decreased significantly as compared with the wear in the medium with H20 .

The most significant decreasing was observed in the medium with the solution of ammonium sulphate - (NH4)2S04.

The results of the experiments showed that the industrial fertilizers have a passivating effect and the surface of the metal exhibited character of passivity in the soil which contains an inorganic solutions by forming secondary structures with higher stability and mechanical properties.

The results show that wear intensity of agricultural machines functional parts in the soil can be decreased by using suitable passivators.
