Abstract
Przedmiotem wynalazku jest sposób modyfikacji laserowej warstwy wierzchniej żeliwa sferoidalnego w którym obrabianą powierzchnię warstwy wierzchniej żeliwa sferoidalnego pokrywa się powłoką stopującą składającą się z substancji stopującej i wiążącej, przy czym substancją stopującą jest amorficzny bór. Następnie obrabianą powierzchnię poddaje się laserowej obróbce cieplnej polegającej na stopowaniu z gęstością mocy wiązki laserowej w zakresie 40 - 160 W/mm2 oraz prędkość posuwu 4 - 16 mm/s, z jednostkowym czasem nagrzewania obrabianej powierzchni równym 0,2 - 1 s.The subject of the invention is a method of modifying a laser surface layer of ductile iron in which the surface of the surface layer of ductile iron is treated with an alloying coating consisting of an alloying and binding substance, the alloying material being amorphous boron. Then the treated surface is subjected to laser heat treatment consisting of alloying with a laser beam power density in the range of 40 - 160 W / mm2 and a feed speed of 4 - 16 mm / s, with a unit heating time of the treated surface of 0.2 - 1 s.
