Company Profile: Gleason Corporation 30 By Stephen Sisk Gleason Corporation celebrates its 150th anniversary with eyes intently set on the future of gear manufacturing. High Temperature Vacuum Carburizing Drives Alloy Development 36 By Bill Gornicki With gear surfaces, a growing demand for greater fatigue resistance can only be achieved by specialized heat treatments. Vacuum carburizing — low pressure carburizing — is a process that can be used to apply hardness, wear resistance, and increased fatigue life in specific parts.

  • The Effects of Austempering and Induction Hardening on the Wear Properties of Camshaft Made of Ductile Cast Iron
    Vol. 131 (2017) ACTA PHYSICA POLONICA A No. 3 Special Issue of the 6th International Congress & Exhibition (APMAS2016), Maslak, Istanbul, Turkey, June 1–3, 2016 The Effects of Austempering and Induction Hardening on the Wear Properties of Camshaft Made of Ductile Cast Iron B. Karacaa;∗ and M. Ş˙ımş˙ırb aESTAŞ Eksantrik San. ve Tic. A.Ş., 58060 Sivas, Turkey bCumhuriyet University, Engineering Faculty, Department of Metallurgy and Materials Eng., 58100 Sivas, Turkey The aim of this study is to investigate the effects of heat austempering and induction hardening on the wear properties of GGG60 ductile cast iron for camshaft production. For this purpose, camshafts have been produced by sand mould casting method. Fe-Si-Mg alloy has been used for inoculation process to achieve iron nodulization. The casting has been done between 1410–1420 ◦C. The casted camshafts have been austenitized at two different temperatures (800 and 900 ◦C) and time intervals (60 and 90 min) under controlled furnace atmosphere. The austenitized camshafts have been quenched into the molten salt bath at 360 ◦C, held there for 90 min and then cooled in air. This way, austempering heat treatment has been applied. After that, surface hardening process was conducted using induction hardening machine with medium frequency. Microstructure of camshafts has been examined by optical methods and mechanical tests have been performed. Results show that austempering heat treatment increases the wear resistance of camshaft, compared to as-cast condition. Wear resistance of the camshaft increases with increasing austenitizing temperature, time and with induction hardening. The lowest weight loss of 0.62 mg has been obtained for the induction hardened camshaft austenitized at 900 ◦C for 90 min.

  • Hardness and Case Depth Analysis Through Optimization Techniques in Surface Hardening Processes K
    38 The Open Materials Science Journal, 2010, 4, 38-63 Open Access Hardness and Case Depth Analysis Through Optimization Techniques in Surface Hardening Processes K. Palaniradja*, N. Alagumurthi and V. Soundararajan Department of Mechanical Engineering, Pondicherry Engineering College, Pondicherry – 605 014, India Abstract: Surface engineering and surface engineered materials find wide applications in engineering industries in recent years. Inconsistency in hardness and case depth has resulted in the further optimization of the process variables involved in surface hardening. In the present study, the following operating parameters viz. preheating, carbon potential, holding position, furnace temperature, carburising time, quenching medium, quenching temperature, quenching time, tempering temperature and tempering time were taken for optimization using the Taguchi and Factorial design of experiment concepts. From the experiments and optimization analysis conducted on EN29 and EN34 materials it was observed that furnace temperature and quenching time had equal influence in obtaining a better surface integrity of the case hardened components using gas carburizing. Preheating before gas carburizing further enhanced the surface hardness and the depth of hardness. In the case of induction hardening process, power potential played a vital role in optimizing the surface hardness and the depth of hardness. Keywords: Pinion, hardness, case depth, taguchi techniques, optimization, process variables. 1. INTRODUCTION In this study, Taguchi’s Design of Experiment concept has been used for the optimization of the process variables of Changing demands of dynamic market place have Gas Carburizing process and Factorial design of Experiment improved and increased the commitment to quality for the optimization of process variables of Induction consciousness.
