Popis:	The results on the impact of additives on the ultra-fine composite powder system, obtained by MASVS on the tribotechnical properties of friction material based on tin bronze with 12 % of tin are presented. It is shown that the powder additive in the range of 0.5–2.5 % increased the dynamic friction coefficient from 0.040 to 0.051. The introduction of a 1.5 % composite powder reduced the surface roughness of the counter body from 2.9 to 0.9 μm. The change in the tribotechnical properties is due to the structural changes in tin bronze, the additive particles, the surface layer of the friction material and the counter body.
