- Abstract
- In this article, we study the influence of the cubic boron nitride (CBN) particle size in nano/micro CBN particle-coated tools on the fatigue performance of hard-machined AISI 1053 steel. The effect of the CBN particle size on the crack initiation life and the crack propagation life is reduced significantly with increased loading, whereas the crack propagation life is more influenced by the CBN particle size compared with the crack initiation life. The CBN particle size can influence the crack initiation life by 96 % and the crack propagation life by 130 %. As a result, it can influence the fatigue life by 370 % at the maximum Hertzian stress of 2,724 MPa. The results demonstrate that the CBN particle size influences the fatigue life and that the effect of the CBN particle size on the fatigue life can be lessened significantly if the loading is increased to a certain level that depends on the function of machined surfaces.
