Research on the optimization of the manufacturing technology of the metal parts heat treated in liquid and solid phase
Journal Title: Proceedings in Manufacturing Systems - Year 2018, Vol 13, Issue 3
Abstract
This paper analyzes the quality of pinion type parts manufactured through the technological procedure of hardening in liquid and solid state phase. The investigations are made by electronic microscopy and optical microscopy, highlighting the structure and composition of the superficial layer and the micro-hardness determinations. Depending on the results obtained, the paper suggests measures for optimization, aiming especially at the values of the most important technological parameters for the technological phase of microalloying in liquid state and induction heat treatment in solid state phase. The hardening of the superficial layer of the pinion type parts is revealed by the high values of the micro-hardness determinations. The hardening and structure of the superficial layer are supporting the implementation of the technological procedure at industrial level.
