Physical properties of electroless nickel-tungsten coating on mild steels obtained from acetic bath

Electroless deposition of nickel tungsten on mild steel was conducted using acetic bath, containing nickel sulphate and sodium tungstate in the alkaline medium. The influence of sodium acetate and sodium tungstate on deposits was investigated and characterized using scanning electron microscope (...
