Abstract
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.Trivedi’s 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, d50 and 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.
Highlights
Brass, an alloy mainly consist of copper (Cu) and zinc (Zn), is widely used in various industries because of their good formability, high corrosion resistance, strength to weight ratio, and ductility
The significant reduction of particle size found in d50 and d99 suggest that percent of coarser particles in brass powder were reduced after biofield treatment
Study reports the influence of biofield treatment on brass powders at its structural and physical properties
Summary
An alloy mainly consist of copper (Cu) and zinc (Zn), is widely used in various industries because of their good formability, high corrosion resistance, strength to weight ratio, and ductility. The control and treated samples were characterized by using particle size analyzer, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy. Vc and Vt are the unit cell volume of control and treated powder samples respectively Lc and Lt are crystallite size of control and treated powder samples respectively.
