Wear Conditions of Al₂O₃-TiC/Al₂O₃-TiC-CaF₂ Laminated Ceramic Drawing Die Used for 45#Steel Drawing Process

Abstract:

Al₂O₃-TiC/Al₂O₃-TiC-CaF₂ laminated ceramic drawing die used for drawing experiment was prepared by vacuum hot pressing method. The finite element models of 45#-steel and wire drawing die were built by SolidWorks and simulation analysis of drawing process were done by FEM simulation software. The axial stress, strain distribution and drawing force during deformation were got. The microstructure of the worn drawing die was observed by scanning electron microscopy (SEM) and the composition was investigated by energy dispersive X-Ray spectroscopy (EDS). Results show that the wear conditions of Al₂O₃-TiC-CaF₂ material layers were serious than Al₂O₃-TiC. And because of the dragging effect, solid lubricating films formed in Al₂O₃-TiC-CaF₂ material layers covered on Al₂O₃-TiC material layers. The drawing die owes self-lubricating performance. Without considering friction effective on invariable zone of the drawing die, the simulation result of drawing force was smaller than the measurement value.
