In this work the effect of titanium particles on wear of electro less Ni–P–TiO2 composite coatings deposited on mild steel substrates at different annealing temperatures. Electro less process is an autocatalytic reduction method in which metallic ions are reduced in the solution. Micro composite coatings of Ni-P-TiO2 on mild steel are deposited by varying volume of TiO2 nano-powder by electro-less method from Ni-P plating bath containing Nickel chloride as a source of nickel ions, sodium hypophosphite as the reducing agent, ammonium hydroxide as a complexing agents and TiO2 micro powder. Electroless Ni-P-TiO2 coating have been widely used in the chemical process industries, mechanical industries, and electronic industries due to their excellent mechanical properties. In the present work, deposition of Ni-P alloy coating and Ni-P-TiO2 micro composited coatings were done on the mild steel and hardness properties were studied.
