In the nitriding process, materials are toughened at temperatures between 400 °C and 900 °C. The goal of this study is to create a gas nitriding furnace that is portable, automated, suited for all industrial conditions, and equipped with a modular instrumentation system for furnace automation. To improve furnace efficiency and operating time nano coatings are suggested for insulating material or fins, in the previous work quartz and glass structure, particle sized nano coatings are used for furnace to improve thermal resistivity and operate at low cost. The automated gas nitriding furnace is being designed and studied using the principle of heat transfer. It was created for diverse experimental reasons. a furnace with efficient operating conditions that can produce nitrogen at a specific temperature in a confined chamber. The refractory bricks are formed between sheets of low carbon steel with nano coated material that make up the furnace’s outer face. In the Creo 3D modeling software, the components of the gas nitriding furnace are modelled with all of the furnace’s dimensions, and the modeled components are built in the same 3D modeling program. The software ANSYS Workbench 2022 R2 analyzes the total deformation and thermal stresses using static structural analysis and steady state thermal analysis. The main objective of this paper is to design portable gas nitriding furnace for diverse applications which can be operated from remote places with constant monitoring. The instrumentation for the furnace is controlled and automated in this project using Arduino and IoT (Internet of Things) technology. In the gas nitriding furnace, the temperature, voltage, gas mixture ratio, and pressure are all automatically controlled. This furnace is operated by the Node MCU ESP8266 Microcontroller from remote places also.
