Significance Of Thermal Barrier Coating In Din 2714

Abstract

A significant issue with the hot forging process is the intense stress and high temperatures involved, which can
cause the die to fail. This research examines how to prevent die failure by applying a glass coating to the die's
surface. The focus is on a die made of Din 2714, a type of German standard steel, during the hot forging of
waspaloy. Forging was attempted using the traditional method, which is challenging due to the heat escaping
from the die's surface and the limited temperature range of waspaloy. To address this, a thermal barrier coating,
Delta Glaze FB412, was applied to the die's surface. Thermal analysis was performed using Ansys software,
revealing that the coating effectively reduced heat loss from the die's surface. To confirm these findings, two
halves of the die's surface were coated with Delta Glaze FB412. After the die underwent adequate heat treatment,
it was installed on a forging machine, and the forging process was conducted according to the product's
production procedures. Upon completion of the forging, it was observed that the product was defect-free.
Further examination after the process showed no signs of die failure or plastic deformation.
