Abstract
In this article, research on the process of induction hardening on the Saina vehicle’s Tulip part, which is made of 1055 steel, was investigated. The input parameters discussed in this article include induction power, hardening time and cooling fluid pressure, and in the output parameter, surface hardness and effective case depth were investigated. Using the test design table extracted from the Minitab software and the analyzes performed with the response surface method, the mathematical and statistical equations governing the process were extracted, and using the analysis of variance table, the ineffective parameters of the process were removed and the final regression equation and other required information was extracted. Then the optimization of the process according to the desired values to achieve the desired surface hardness and effective case depth were done by providing a suitable range of induction power settings, induction time and cooling fluid pressure, which helped to reduce destructive tests and increase the quality assurance of parts.
