Sepeda motor dengan kapasitas 150 cc sering digunakan untuk balapan di Indonesia. Tekanan tinggi dan berulang yang diterima piston selama kompresi menimbulkan beban fatigue pada connecting rod. Pada beberapa kasus, rod dapat terjadi buckling (bengkok) atau fracture (patah) bagian kritisnya akibat tidak kuat menahan dari piston. Untuk mengantisipasi terjadinya maka diperlukan pemilihan material ...

The aim of this study was to determine the impact additions tungsten carbide and silicon microparticles lubricant used in burnishing process on tribological properties friction pairs. cylinders made AISI 1045 steel constituted a workpiece. Burnishing with SN150 base oil addition microparticles. tested materials were burnished forces 1000 N 1500 N. Before after process, surface roughness hardnes...

The rapid growth in the use of Micro/Nano products in variety of industries such as Micro electromechanical systems (MEMS), microelectronics, Biomedical/Bio-MEMS, automotive (motion sensors), telecommunications etc, has demanded new micro manufacturing methods. The challenge with the manufacturing of Microfluidic devices/biochips is that they often make use of broad range of materials within a ...

The microstructures of chromium and iron borides formed during laser surface alloying of AISI 1045 steel with CrB were examined by transmission electron microscopy combined with selected-area electron diffraction and X-ray-dispersive spectroscopy. It was found that the heavily faulted (Cr, Fe)2B phase contains a microsyntactic existence of several polytypes, including one-dimensionally disorder...

The objective of this research is to compare the cutting parameters of turning operation the work pieces of medium carbon steel (AISI 1045) by finding the longest tool life by Taguchi methods and Response Surface Methodology: RSM. This research is to test the collecting data by Taguchi method. The analyses of the impact among the factors are the depth of cut, cutting speed and feed rate. This r...
