In this research, surface properties of different types of single layer and hybrid Ni-P/Ni-B coatings prepared by electroless plating were investigated with the aim of optimizing their tribological properties. Martensitic stainless steel type 410 which has received a lot of interest in petroleum and power applications was used as substrate material. Acidic bath was used in order to deposit single layer Ni-P coatings including low, medium and high phosphorous coatings; By varying the pH of the bath in the range of 4.3-6.7, aforementioned coatings were formed with a thickness of 30 ?m. To obtain a single layer Ni-B coating, basic bath with a pH of 13 was used and a 30 ?m thick coating was deposited on the substrate. In order to obtain hybrid coatings, surface preparation was done on substrates. First, substrates were immersed in electroless Ni-P bath and remained until formation of a 20 ?m thick coating. Then they were plunged in nickel strike bath in order to improve the adhesion of Ni-B coating to the intermediate layer. Finally, samples were put in an electroless Ni-B bath and kept until the deposited coating reached a thickness of 10 ?m. In order to investigate and compare the tribological properties of coatings in as-deposited and heat treated conditions, heat treatment was done on each coating for 1 hour at 400 °C. Evaluated surface properties include morphology, roughness, hardness, wear and friction coefficient which were studied using scanning electron microscope, X-ray diffraction analysis, optical microscope, vickers microharness testing machine, surface profilometry and pin on disc wear test machine. The results of evaluating the morphology of Ni-P coatings indicated that higher phosphorous content in coating results in finer morphology and lower roughness. Also, obtained results showed the similarity between Ni-B and Ni-P morphologies; However, Ni-B coating had relatively higher porosity content and roughness due to high deposition rate. Heat treatment on electroless Ni-P and Ni-B coatings lead to an increase in hardness and wear resistance and also a decrease in friction coefficient. Therefore, heat treated high phosphorus coating had the highest hardness value (about 1010 HV) and wear resistance and the lowest friction coefficient (about 0.44) among all heat treated and as-deposited single layer Ni-P coatings. For single layer Ni-B coatings, heat treated coating showed the highest hardness value (about 1130 HV) and wear reasistance and the lowest friction coefficient (0.44) among as-deposited and heat treated single layer Ni-B coatings. Evaluation of the morphology of hybrid coatings showed that Ni-High P/Ni-B hybrid coating has finer morphology and lower roughness compared to Ni-medium P/Ni-B and Ni-low P/Ni-B. Also, Ni-low P/Ni-B coating despite of the lower hardness gradient, has lower hardness and wear resistance. Among as-deposited and heat treated electroless hybrid coatings, Ni-high P/Ni-B coating had the highest hardness value (about 1320 HV) and wear resistance and the lowest friction coefficient (0.37). Weight loss results of heat treated Ni-high P/Ni-B electroless coating, as the best hybrid coating, indicated an 85% improvement in wear resistance compared to heat treated Ni-B electroless coating as the best single layer coating. So, Ni-high P/Ni-B electroless coating showed the best tribological properties among different single layer and hybrid coatings.
