논문 초록 (Abstract)
The plasma vapor coatings on two kinds of die steels have been carried out in order to identify the most optimized conditions. When TiN or TiAlN coatings were carried out on the substrates, the coating layer thicknesses were not significantly changed, and the optimized coating thickness was identified as ~ 5 ㎛. When the optimized coating conditions and stress analysis were applied to the primary piston dies for fabrication of aluminum cylinders, an extended life time of the die was observed. The methodology for extending the life time of dies was discussed in terms of microstructures and stress analysis.
