Multiple Performance Optimization of Carburized Steel Using Taguchi Based Moora Approach

Abstract

In this research, a multi-response optimization based on Taguchi method-based MOORA (Multi-response optimization based on ratio analysis) is proposed for carburization process of low carbon steel. Experiments were designed using (Taguchi's) method with six input carburization factors (carburization temperature, carburization time, tempering temperature, tempering time, activator wt.%, and quench media). Depth case and wear rate were considered as the most response measures in this study. Results of the analysis shows that the carburization temperature is the most significant variables for the optimum outcome results. The desired response measures and mathematical model were achieved and used as optimum condition tool. The outcome of this study had been explored the possible use of the developed carburized steel in high wear resistance applications.

Mechanical Properties Of Pack Carburized AISI 4340 With Variation Energizer Composition of Barium Carbonate (BaCO3) And Sodium Carbonate (Na2CO3)

“…The effect of the carburizing parameter, such as carburizing temperature, carburizing media, immersion time, carburizing composition, and cooling method, affects the hardness value and the depth of the steel layer. The higher the carbon carburized, the more carbon will be diffused, so the higher the surface hardness of the steel [7], [8]. Based on the description above, in this study, variations in the composition of the energizer on the carburizing pack will be carried out on the mechanical properties (tensile strength, hardness, and impact strength) and the characteristics formed from the results of these tests.…”

Optimasi Parameter Karburisasi Temperatur Rendah Pada Baja Tahan Karat Austenitik Menggunakan Metode Taguchi

“…Dalam bidang perlakuan panas termokimia khususnya proses karburisasi, penerapan metode Taguchi belum banyak diteliti terutama untuk material baja tahan karat tipe austenitik. 2018) menggunakan metode Taguchi untuk mengoptimasi parameter proses karburisasi untuk material baja karbon rendah [22], [23]. Kedua penelitian tersebut menggunakan 9 eksperimen dengan beberapa faktor tertentu yang dilibatkan seperti waktu perlakuan, temperatur perlakuan, waktu perendaman spesimen dalam minyak, persentase aktivator, dan lain-lain.…”
