Abstract

Accurate and stable temperature control is essential in laboratory-scale thermal processing, as it directly influences process stability, operational safety, and experimental reproducibility. However, many laboratory thermal systems still rely on manual regulation or simple heating mechanisms without adequate feedback control, resulting in temperature fluctuations and inconsistent performance. This study presents the design and implementation of an embedded temperature control system for laboratory-scale thermal processing, using pyrolysis as an application case study. The proposed system is based on a closed-loop control architecture that integrates a K-type thermocouple, a microcontroller-based control unit, and an electrical heating actuator. A hysteresis-based on–off control strategy is implemented to regulate the heating process and maintain the desired temperature setpoints. The system performance is experimentally evaluated at operating temperatures of 300 °C, 400 °C, and 500 °C under different processing durations. Experimental results demonstrate that the developed system provides stable and reliable temperature regulation across all tested conditions. The system exhibits a rapid heating response, minimal overshoot, and acceptable steady-state temperature deviations, even at elevated operating temperatures. Long-duration operation confirms the robustness and reliability of the control strategy. These results indicate that the proposed embedded temperature control system offers a practical and cost-effective solution for laboratory-scale thermal processing applications requiring stable and repeatable temperature control.

Abstract

This study investigates a bio-based pack carburizing treatment for AISI 316L austenitic stainless steel using an environmentally friendly carburizing mixture composed of 70% Alaban wood charcoal and 30% eggshell powder. The treatment was conducted to improve the surface properties of AISI 316L for potential use in non-implant metallic components of electromedical devices. Solid-state pack carburizing was performed at 600 °C, 700 °C, and 800 °C for 3 h. The treated specimens were evaluated in terms of surface carbon content, microstructural changes, diffusion layer thickness, surface hardness, and hardness distribution. The results showed that increasing carburizing temperature enhanced carbon absorption and surface modification. The highest surface carbon content of 0.80% was obtained at 800 °C. At the same temperature, the surface hardness increased to 346 HV, and the maximum diffusion layer thickness reached 16.7 µm. Microstructural observations revealed the gradual formation of a darker and more continuous carbon-enriched modified layer as the carburizing temperature increased. These improvements indicate that the treated surface became more resistant to localized deformation, repeated contact, and light friction, which are important factors for maintaining the durability and functional reliability of metallic parts in electromedical devices. These findings indicate that the Alaban wood charcoal–eggshell powder mixture can act as an effective bio-based carburizing medium for improving the surface durability of AISI 316L stainless steel. Therefore, the proposed treatment not only enhances the surface performance of AISI 316L but also offers a sustainable and low-cost surface engineering approach for non-implant electromedical components exposed to repeated handling, cleaning, and maintenance activities.
