摘要

Powder technology is considered one of the promising technologies that industrial companies have resorted to in the manufacture of mechanical parts in recent years instead of casting processes and traditional manufacturing methods that lead to a large loss of materials and high energy consumption. In this research, the effect of adding nano titanium oxide and nano zinc oxide will be studied separately and in different weight ratios (2%, 4%, 6%, 8% and 10%) on the mechanical properties of mild steel powder. A pressure of 450 MPa is applied to the powder inside the mold and then it is placed in the tube furnace with argon inert gas for annealing at a temperature of 850 °C for four hours were used. Ultimate tensile, compression and Micro Rockwell hardness tests were conducted. Morphological properties of samples were investigated by using a scanning electron microscope and X-ray diffraction spectra were studied for all samples. The results showed that increasing the weight fractions of nanomaterials to the maximum increases the tensile strength, compressive strength and Micro Rockwell hardness by 25%, 18% and 13%, respectively. The scanning electron microscope images (SEM) also showed the presence of cohesion and homogeneity in the crystal structure for all weight ratios of nanomaterials gradually. The X-ray diffraction results also confirmed the presence of new phases formed after the process of mixing mild steel powder with nanomaterials. As a human-friendly material, stainless steel is used in many medical applications to join broken bone fragments in humans and other animals, especially when non-toxic materials such as zinc oxide and nano-titanium oxide are added in appropriate weight ratios.
