Title
Behavior of Black Oxide Layer Formation on HSS Roll Material for Hot Finishing Mill
김진수Jin Soo Kim,최진원Jin Won Choi,김동규Dong Gyu Kim
Abstract
The behavior of black oxide layer formation on the high speed steel(HSS) roll materials for hot strip mill has been studied. High temperature oxidation experiments were performed at both dry and wet atmospheres. Surface oxide scale was preferentially formed on the matrix and grew laterally to the top of carbides with oxidation time. Spalling of the oxide scale initiated at the interface between external oxide layer and carbide. Ti-treated specimen showed an increased weight gain during oxidation. This can be attributed to the fact that Ti treatment results in finer crystallized carbides, leading to the increment of interface area between carbides and matrix, thereby promoting break away oxidation. Under the dynamic wet oxidation atmosphere, growth of oxide scale at scale/air interface was restricted physically by the applied force, whereas the growth at scale/metal interface progressed independently.
