Abstract

The increasing application of micro electro mechanical systems technology on daily life devices increases the need for micro components. Furthermore, it must be supported by reliable fabrication technology to produce micro-sized products. One of these technologies is micro-sheet metal forming, which is a forming technology from sheet metal with 10-300µm thickness. The development of this technology requires a special press machine that is used in the scope of micro-scale work, named micro-press. Micro-press is still rare due to it was used for individual experiment purposes. Thus, it is necessary to develop the micro-press to support research and manufacturing of micro-part. In this study, the design of a micro-press is intended to accommodate the miniaturization problems and to be easy in fabrication and re-fabrication. Then, the micro-press will contribute to fulfill the micro-parts need. By using the VDI 2222 design method, the design of a 5kN micro-press machine with a servo motor drive is obtained, and validation of construction strength was carried out with the help of the appropriate CAE software. The results of the design validation show that the construction of the micro-press machine is quite strong. The selected component has a strength specification that is greater than required, and the maximum stress that occurs in the frame, which is 80.096 N/mm2, is still very lower than the allowable stress on the SPHC material. The magnitude of the resultant displacement shows a fairly small value, i.e. 0.178 mm.

Abstract

Tribocorrosion is a type of material degradation caused by simultaneous wear and corrosion of metal surfaces caused by laminar or turbulent flow. Additive manufacturing technology plays an important role in its application to precision components and complex assemblies. This study developed a 316LX material with Fe, Ni, Cr, and other powder alloys that was processed into an ultra-protective wire as a 3D printing filler. This simulation of tribocorrosion conditions was performed on a triboester machine. This simulation is expected to provide important insights and understanding into the behavior and properties of the 316LX 3D printing material, especially when exposed to abrasion and corrosion conditions in a sulfuric acid solution environment. Corrosion Rate Testing of 316LX Material Additives Using Potentiodynamic Methods in a Modified Rotating 5% Sulfuric Acid Fluid. In addition to corrosion rate, the Vickers hardness, metallography, and shrinkage of the 316LX green part material were also tested at 1000oC after sintering.
