Title of the thesis:Tribological properties of friction pairs Si3N4 - stainless steel
Summary:The aim of this work was to analyze tribological behavior of silicon nitride in a friction pair with stainless steel. Part of work was production of ceramic samples Si3N4 containing 5% sintering additives YAG. After metalograhic preparation was measured density, hardness and fracture toughness of samples. Tribological properties were determined by tests in which ceramic samples were in contact with steel discs and hard abrasive material Al2O3. Observed values were evaluated in terms of impact of load, concentration of sintering additives and sintering times on the tribological behavior of silicon nitride.
Key words:wear, friction, stainless steel, silicon nitride
