On the project

Cílem projektu je stanovit vliv molekulární degradace maziv na bázi polymerů na utváření mazacích filmů v kontaktech třecích povrchů velmi zatěžovaných strojních součástí. V rámci projektu bude ukázán možný vliv molekulární degradace na redukci tloušťky mazacího filmu. Bude kvantifikována míra této redukce s ohledem na molekulární hmotnost maziva. Bude ukázán vliv molekulární degradace na úlohu mazivostních přísad na bázi polymerů při utváření mezných mazacích filmů.
