Abstract: Influences of thiourea on electroless nickel deposition rate, hydrogen evolution, polarization curves and stationary potential wore determined. Together with the X-ray photoelectron spectroscopy (XPS) analysis of the deposit. the mechanism for acceleration and stabilization of electroless nickel deposition by thio-urea has been discussed.

Key words: thiourea, eleotroless nickel deposition, acceleration, stabilization, mechanism
