dc.description.abstractIšvystytos pramonės valstybėse atlikti tyrimai parodė, kad dėl dilimo pasaulyje kasmet patinami milžiniški nuostoliai - iki 4 % bendrojo vidaus produkto. Nustatyta, kad investicijos įtribologinius tyrimus valstybei kasmet gali sutaupyti 1,0-1,4 % BVP. Šiame darbe atlikti elektraiankiniu būdu apvirintų Fe-C-Si-Cr-Ti-B sluoksnių, abrazyvinio dilimo į įtvirtintą abrazyvą (A12O?) tyrimai. Nustatyta, kad apvirintų sluoksnių kietumas turi tiesioginę įtaką dilimui - kuo sluoksniai kietesni, tuo atsparumas dilimui didesnis. Paviršius intensyviai dyla pjaunant. Tai rodo didelę abrazyvo ir apvirinto sluoksnio kietumų skirtumų įtaką. Mažiausiai dilo mėginys turintis C - 1,6 %, Cr - 4,4 %, B - 0,56 %, Mn - 0,9 %, Si - 1,44 %, Ti - 0,59 % bei Fe - 90,2 %lt
dc.description.abstractIndustrialized countries studies have shown that because of wear in the world suffered huge losses every year - up to 4 % of the gross national product. It was found that investments in the tribological research annually can save from 1 to 1,4 % of gross national product. In this paper was performed the abrasive wear research of arc welded Fe-C-Si-Cr-Ti-B surfaces into embedded abrasive. The microhardness of arc welded layers has a direct impact on abrasion - the harder layers, the higher resistance to abrasive wear. In SEM picture visible cutting traces of wear, and only small fragments are chipped. This phenomenon demonstrates the high abrasive and metal microhardness differences influence. The highest wear resistance shows sample with C - 1,6 %, Cr - 4,4 %, B -0,56 %, Mn - 0,9 %, Si - 1,44 %, Ti - 0,59 % and Fe - 90,2 %en
