“…Higher thermal conductivity of the quench medium would increase the cooling rate of the steel during the quenching process. Therefore, the hardness value of the steel will be higher due to the increasing number of the bainite and martensite phases in the microstructure [36,37].…”

Particle dispersion in the quench medium can alter its properties, particularly its thermal conductivity. Modulating the quench medium’s thermal conductivity can impact the steel’s hardness after heat treatment. In this study, micron-sized particles of carbon biomass derived from coconuts were obtained by milling the biomass via wet and dry methods. The milling duration for both methods was 10, 15, and 20 h, while the speeds were 250, 500, and 750 rpm for each duration. Particle size analysis revealed that dry milling could decrease the particle size by up to 60% from its initial size, whereas wet milling could only decrease it by up to 43%. A thermal conductivity test was conducted on the water-based quench medium supplemented with milled particles, demonstrating an increase in thermal conductivity up to 0.68 W/mK and 0.83 W/mK for dry and wet milling, respectively. All steel quenched with particle-added quench medium showed a hardness up to 21% higher than steel quenched with distilled water. The increase in hardness suggests that the cooling rate during quenching was faster because of the additional dispersed particle, determined by the quench medium’s thermal conductivity.

“…Smaller particles will have a wider surface area to transfer the heat from the surrounding fluid than larger particles. Planetary ball mills are commonly used to reduce the size of solid particles [19,20] . During milling, the shear and impact force between the particle-particle and the particle-jar will break the large particle into smaller ones [21,22] .…”

Solid particles have a higher thermal conductivity compared to a fluid. Therefore, it is a common practice to disperse solid particles inside a base fluid to increase its thermal conductivity. The particle-dispersed fluid is called a thermal fluid. Thermal fluid, such as a coolant, is widely used as a heat transfer fluid. Several types of particles can be used to increase the thermal conductivity of the fluid, i.e., metallic particles, metal-oxide particles, or even carbon-based particles. In this research, a carbon-based particle was used as the dispersed particle. The particle was obtained by processing electronic waste, specifically Printed Circuit Board (PCB). The PCB was pyrolyzed for variable duration at 15, 30, and 45 minutes to increase the carbon content. After pyrolyzing, the particle was milled to reduce its size. Subsequently, the PCB particle was added to distilled water. Sodium Dodecylbenzene Sulfonate (SDBS) was added as a surfactant to increase fluid stability and prevent particle agglomeration. Thermal conductivity was improved by up to a 13% increase at the 15-minute pyrolysis. Adding SDBS surfactant also improves the thermal fluid's stability to -29,1 mV. The fluid's viscosity was slightly increased up to a maximum of 0.984 mPa.S.
