STUDY OF THE USE OF NANOFLUIDS WITH PERCENTAGE OF CARBON NANOTUBE CONCENTRATION FOR OPTIMIZATION OF THE TEMPERING PROCESS

Abstract

Tempering is one of the most widely used metallurgical processes since its discovery, with the aim of achieving improved hardness and mechanical strength properties. It consists of two stages: heating and rapid cooling. The article below presents the results of a final course project in the form of a scientific article on the application of carbon nanotubes with different concentrations. These were diluted in water at concentrations of 0.05%, 0.1%, and 0.2%. Afterward, the submerged pieces were cut in half using a cut-off method and analyzed through an optical microscope. Additionally, hardness was assessed using the Rockwell C test. Based on the methodology and equipment used for the measurements, it was found that there was no significant change in the results of the heat treatment when using carbon nanotubes.
