Tribological Properties of Electroless Nanocomposite Deposits with Influence of Aliquat 336 on 6061 Aluminium Alloy

摘要

The process of electroless nanocomposite deposit on 6061 aluminium alloy was significantly enhanced with influence of Aliquat 336. The present investigation dealt with the analysis for the influence of Aliquat 336 surfactant on tribological properties of ENi-P-ZnO nanocomposite deposit on 6061 aluminium alloy sample. Wear resistance was calculated by pin-on-disc tribometer wear testing machine for the coated substrate by varying the surfactant concentration. Addition of surfactant has shown significant enhancement in the wear resistance of the coated surface. Surfactant was distinctively added in the chemical bath which resulted in decline of the surface tension, helped to bind the particles of nickel to the bubbles of hydrogen gas produced throughout the process of deposition. However, the impact of surfactant reached to its maximum value (critical micelle concentration) and got stabilized. The surface morphology and phosphorus content were characterized by field emission of scanning electron microscopy and energy dispersive X-ray analysis respectively. The worn surface morphology also revealed the abrasive wear mechanism. The complete experimental details, results obtained and their analyses have been presented in this paper.
