Optimization of process parameters to improve the wear resistance of the mild steel using electroless Ni-P coating process

The electroless coating has several advantages over other
coating techniques available in the market. They are the
formation of a uniform deposit on irregular surfaces,
direct deposition on conductors and surface activated non
– conductors, formation of less porous in the deposits,
very good wear resistance and corrosion resistance. In
addition, it has few drawbacks of EN coating are the cost
of chemicals used are high, poor nickel recovery from the
bath, electroless nickel bath decomposition. Due to these
reasons, the EN coating process efficiency is reported to
be poor and is of the order of only 50%. Hence it is felt that
a detailed investigation on the possibility of improving the
coating efficiency and wear behaviour of electroless
coatings by optimization techniques. The main objective
of this work is to investigate the process parameters
influencing the wear behaviour of the electroless Ni-P
coating process. The result showed that after optimization
of process parameters, the confirmat
