Elevated Temperature Stress Analysis of Cobalt-Based Composite Cladding by Microwave Process on Gas Turbine Rotor Blade Using FEA

An electromagnetic field provides energy to the material directly during microwave processing. As a result, there are less thermal gradients and a quick heating of the entire material thickness. Additionally, volumetric heating can conserve energy and shorten production times. In the current study, a 900-W power level and 2.45-GHz microwave furnace were used to generate a cobalt-based coating on titanium substrate. The processing time is approximately 20 min. This report presents a review on microwave heating and describes the procedure for the development of clad. The latter part of this report deals with a thermal analysis using ANSYS software to determine the temperature gradient being created by the cobalt-based coating on two models: a regular square-shaped body and a gas turbine rotor blade.
