The effect of several Almen intensities of shot peening on the corrosion behavior, surface roughness, micro hardness profiles, and residual stresses of stainless steel AISI 316 L were investigated. Hydroxyapatite coating (HA) were applied to shot peened materials to improve their corrosion resistance. The corrosion behaviour were studied using potentiodynamic polarization. The electrochemical t...

Pengelasan adalah proses penyambungan logam atau non-logam yang dilakukan dengan memanaskan material akan disambung hingga temperatur las, tanpa menggunakan tekanan dan pengisi. Salah satu teknik pengelasan SMAW (Shield Metal Arc Welding) GTAW (Gas Tungsen Welding). Dengan las tersebut kita dapat menyambung seperti: Aluminium, Tembaga, Carbon Steel, Stainless Steel. Penelitian ini untuk mengeta...

: Surface roughness during electrical discharge machining (EDM)was determined, inwhich material is removed by thermo-electric process due to the occurrence of successive dischargebetween workpiece and electrode. Box-Behnken design (BBD) involving four parameters dischargecurrent (I), Pulse ON time (PON), OFF (POFF) andGap voltage, with three levels wasemployed minimize surface roughness. Other ...

The sintering temperature and holding time have a significant impact on the densification of ceramic compact. In this study, alumina inserts were made with varying temperatures times. procedure began compacting powders inside mould trapezium round shapes. These then sintered between 1200 °C 1400 for 5 to 9 h time. samples underwent analysis based shrinkage size, density, microstructure. sample ...

Welding is an activity of joining two or more metals by heating them until they melt, in which the melted workpieces will unite with help additional materials to form a connection whole piece metal. The purpose this study was determine effect welding current, type electrode and pattern movement on strength welds against impact test order produce optimal strength. method used Taguchi Method. Thi...
