Abstract

Przedmiotem zgłoszenia jest sposób modyfikacji laserowej warstwy wierzchniej żeliwa szarego, w którym obrabianą powierzchnię warstwy wierzchniej żeliwa szarego pokrywa się powłoką stopującą, składającą się z warstwy stopującej, wykonanej z proszku kobaltu o wielkości cząstki 2 µm i czystości 99,8% oraz substancji wiążącej, którą jest powszechnie stosowane szkło wodne. Następnie obrabianą powierzchnię poddaje się laserowej obróbce cieplnej, polegającej na stopowaniu z mocą wiązki laserowej w zakresie 2,0 - 2,6 KW oraz prędkością jej posuwu 16 - 21 mm/s, z jednostkowym czasem nagrzewania obrabianej powierzchni równym 0,18 - 0,25 s.The subject of the application is a method of modifying the gray surface of the gray iron cast iron, in which the treated surface of the gray iron cast surface is covered with an alloying coating, consisting of an alloying layer, made of cobalt powder with a particle size of 2 μm and a purity of 99.8%, and a binding substance which water glass is widely used. Then the treated surface is subjected to laser heat treatment, consisting of alloying with the laser beam power in the range of 2.0 - 2.6 KW and a feed speed of 16 - 21 mm / s, with a unit heating time of the treated surface of 0.18 - 0, 25 p.
