Study on the effect of 1.4-butynediol on the performance of electroplated diamond wire saw

Abstract

In response to the problems of low production efficiency and short service life of electroplated diamond wire saws used in the photovoltaic industry, in order to improve the performance of electroplated diamond wire saws, electroplating solutions with different mass fractions of 1.4-butynediol (0.1 g/L, 0.3 g/L, 0.5 g/L) were prepared by using electroplating methods. Nickel coatings were obtained through customized electroplating tanks, and electroplated diamond wire saws were prepared through electroplating processes. The effect of 1.4-butynediol content (mass fraction) in electroplating solution on the performance of diamond wire saws was studied. A scanning electron microscope was used to observe the microstructure of the coating surface and wire saw section, and the hardness, tensile strength, and wear of the coating with different concentrations of 1.4-butynediol were measured. The results show that among the three ratios, when the mass fraction of 1.4-butynediol is 0.3 g/L, the nickel coating has the best bonding with the metal matrix, the wire saw performance is the best, the coating hardness is the highest (427 MPa), and the wire saw has the least wear (0.092 g).
