Fineness Grade Effect on The Tribological Behavior of Low Carbon Steel Coated by Ni-P-Ptfe Electroless Plating

The paniculate matter co-deposition within the rising film drove to a new obstetrics of electroless composite coating, many of which own stellar corrosion and wear resistance. Thus, it can be used not only for electrically conductive materials such as graphite but also rubber, fabrics, and insulators like plastics. The rate of low coating process can provide better reflectivity of many applications such as plated surface. The aims of this paper are studding the effect of adding the polytetraflouroethylene (PTFE) and the finesse of the low carbon steel samples, which are coated with electroless Ni-P, on the tribiological behavior of the sample’s surfaces. Various concentrations of (PTFE) range, 1g/L, 3g/L and 5g/L in Ni-p composite were examined. The samples, with various surface fineness, were electroless coated by following the procedure of Ni-p plating. After a heat treatment for the plating samples, in 400 ℃ for one hour, was done, the tribological behaviors were tested. The micro hardness was increased by 258 % and the wear rate, which was valued by pin on disk technique, was decreased specific wear rate to 0.2×10−4 mm3⁄N. m.
