| dc.description.abstract | This study presents the research related with abra-sive erosion wear of electric-arc welded hard layers. It is estimated, that when the abrasive particles affect the hard layers surface at oblique angle the wear by microcutting prevails, when they strike perpendicularly – the wear is caused by microfatigue processes. Under abrasive erosion conditions the wear of electric arc welded hard layers is lower if compared to Hardox 400 up to 31% at the abrasive particles impact angle of 30°, and only up to 4% at the perpendicular particles impact. Under the abrasive particles stream impacting the surface at oblique impact angle the most resistant to wear are the layers alloyed with 1.6-1.9% carbon and 4-8% chromium while under the normal impact the most resistant to wear are the low carbon layers alloyed with 0.15% C and high chromium layers alloyed with 15% Cr. | eng |
| dc.description.abstract | Atliktas elektrolankiniu metodu apvirintų kietųjų sluoksnių abrazyvinio erozinio dilimo tyrimas. Nustatyta, kad kietųjų sluoksnių paviršių veikiant nuožulniam abrazyvo dalelių srautui vyrauja dilimas mikropjovimu, o veikiant statmenam srautui, – dilimas dėl mikronuovargio procesų. Abrazyvinio erozinio dilimo sąlygomis apvirinimas kietaisiais sluoksniais nudilimą gali sumažinti iki 31%, kai abrazyvas krinta į paviršių 30° kampu, ir tik 4%, kai abrazyvas krinta statmenai į paviršių. Esant nuožulniam abrazyvo dalelių srautui, atspariausi abrazyviniam eroziniam dilimui yra anglingi (1.6 - 1.9%), 4 - 8% chromu legiruoti sluoksniai, kai srautas statmenas paviršiui, atsparesni yra mažaangliai (0.15%), gausiai chromu (15%) legiruoti sluoksniai. | lit |
