Investigation on Machinability and Damping Properties of Nickel–Phosphorus Coated Boring bar

Abstract: Chatter or self-excited vibration during machining process is always a serious problem which reduces intended dimensional accuracy. This investigation is mainly about reducing induced vibration through the electroless coating of nickel-phosphorus (Ni-P) on high carbon steel (EN 31) boring bar. The high carbon steel (EN31) substrate has been electroless coated with nickel-phosphorus at varying pH values (4, 5 and 6), and the damping effect of pH values on material deposition has been investigated. The coated su… Show more

“…The samples are classified as base metal, coated, and heat treated in a muffle furnace at 400 degrees Celsius for one hour. The heat treatment temperature is chosen based on the literature survey [5,6]. At 400 °C, the hardness of the sample gets peak value due to the transition of amorphous phase into crystalline phase of the Ni-P coating and the formation of Ni 3 P precipitate which further improves the corrosion resistance.…”

“…The increased compliance of cantilever boring bars leads to the need for a constructive increase in their rigidity in manufacturing a hard alloy body and damping rods. It provides the possibility of boring deep holes [1]. However, manufacturing a boring bar from a hard alloy significantly increases its cost.…”
