Brass, a copper-zinc (Cu-Zn) alloy has gained extensive attention in industries due to its high corrosion resistance, machinability and strength to weight ratio. The aim of present study was to evaluate the effect of biofield treatment on structural and physical properties of brass powder. The brass powder sample was divided into two parts: control and treated. The treated part was subjected to Mr.Trivedis biofield treatment. Control and treated brass powder were characterized using particle size analyser, X-ray diffraction (XRD), scanning electron microscope (SEM), and Fourier transform infrared (FT-IR) spectroscopy. The result showed that the average particle size, d50and d99 (size below which 99% particles were present) were reduced up to 44.3% and 56.4%, respectively as compared to control. XRD result revealed that the unit cell volume in treated brass powder was increased up to 0.19% as compared to control. Besides, the crystallite size of brass powder was significantly increased up to 100.5% as compared to control, after biofield treatment. Furthermore, SEM microscopy showed welded particles in control powder, however fractured surfaces were observed in treated sample. In FT-IR spectra, new peak at 685 cm-1 was observed after biofield treatment as compared to control that might be due to alteration in bonding properties in treated brass sample. These findings suggest that the biofield treatment has significantly altered the physical and structural properties of brass powder.
Herein, study reports the influence of biofield treatment on brass powders at its structural and physical properties. A significant decrease in particles size up to 44.3% was found in treated brass as compared to control that may be due to fracturing of powder particles through high energy milling induced by biofield treatment. In addition, XRD data revealed that the biofield has substantially increased the crystallite size in treated brass powder up to 100.5% as compared to control. This increase in crystallite size in treated brass powder may result into higher ductility and machinability. Thus, it is postulated that biofield treatment could be applied to improve the mechanical properties of brass powder for automobile and transport equipment applications.
