Stress analysis and experiment on a split-type ultra-high-pressure die for synthesizing diamond.

In order to obtain a higher pressure-bearing capacity and a larger sample volume and prolong the life of the high-pressure die, a novel high-pressure die for synthesizing gem-grade diamond is investigated with the finite element method. This device is the split-type die, and the cylinder is a combined type. Furthermore, this paper studies the stress distribution of the split-type cylinder and compares it with that of the traditional belt-type die.

Investigation on Bidirectional Pulse Electrochemical Micromachining of Micro Dimples.

Through-mask electrochemical micromachining (TMEMM) is a promising method to prepare micro dimples on the surface of metallic parts. However, the workpiece is machined one by one in traditional TMEMM. This paper introduced bidirectional pulse to TMEMM to improve the machining efficiency.
