: Composite coatings constitute a new class of materials, which are mostly used for mechanical and tribological applications. Among these materials, Ni-P deposition with incorporation of solid-lubricant particles such as polytetrafluoroethylene (PTFE), combine anti-corrosion and wear resistance properties (due to the presence of nickel), with mechanical and tribological performance (due to the presence of particles of PTFE). In this research, PTFE was coated on the specimen surface using spray method or PTFE brushing method, and then, for producing EN/PTFE composite, the specimen will be hold in commercial Ni-P electroless bath. Techniques such as SEM, EDAX, optical microscopy and micro-hardness testing were employed to investigate the effects of some factors such as thickness, deposition rate and coating method of PTFE on the surface. Tribological properties were assessed using pin-on-disk test (wear and coefficient of friction).Results show that, although it is not possible to provide a composite coating with a uniform distribution of PTFE, some properties of EN/PTFE composite coatings produced by suspension method can be expected from these coatings. Also, it was seen that, the friction coefficient of the electroless Ni-P-PTFE composite brush coated steels were decreased in comparing with the Ni-P coated steel up significant value.
