“…135 Studies of mechanical properties included measuring the hardness of the electroless Ni-P coatings; 136 studying the effects of heat treatment on the properties of EN deposits; 137,138 studying the electroless Ni-P-W deposits' wear resistance; 139 investigating the tensile strength and ductility of electroless Ni-P and Ni-B deposits; 140 studying the strength evaluation and effect of graphite on strength of electroless nickel plating on cast iron; 141 and studying the influence of electroless Ni-P deposits on the fatigue and corrosion fatigue properties of plain carbon steels. [142][143][144][145][146] Many researchers studied the tribology and wear 147-154 of Ni-P electroless deposits during this period. Duncan and Arney 140 and Baudrand 155 also studied the superior wear resistance of electroless Ni-B coatings.…”

“…10 On the other hand, when the PHT is carried out around 600°C, it is observed an increase in the corrosion resistance because of the improvement of Ni-P bonding to the steel substrate as well as the integrity of the coating. 1,11 The PHT treatment, however, can also have a significant effect on the steel mechanical properties, as pointed out by Puchi et al [12][13] The PHT produces a softening of steel substrate, due to the exposure of the steel to high temperature, usually higher than the steel tempering temperature. In this work, an introduction of a nitrided layer, 14,15 prior to Ni-P deposition, was tested as a way to avoid the softening of the steel substrate that occurs during the interdiffusion PHT.…”

In this work, electroless nickel has been deposited onto steel substrates by a selfcatalytic process, which involves temperature and time to create a Ni-P layer with a uniform thickness. The major drawback of electroless nickel is the interdiffusion post heat treatment (PHT) that is necessary to create a metallurgical bond between the steel substrate and the Ni-P deposit. The PHT results in softening of the steel. The aim of this ongoing research is to investigate the effect of introducing a nitrided layer prior to deposition of Ni-P layer, as an attempt to lessen the softening of the steel. To this end, Ni-P coatings were obtained over nitrided and non-nitrided steel substrates. The PHT was done at 400°C or 610°C. The nitrided layer, indeed, avoided the softening of the steel substrate. In addition, the nitrided layer improves the adhesion of the Ni-P coating even when the PHT was done at 400°C.

“…On the contrary, if these deposits contain higher P contents will induce compressive residual stresses. Some studies [13][14][15] have reported that there is an increase in the fatigue life of steels coated with EN deposits of 12% P without post-heat treatment (PHT). PHT commonly applied to EN deposits produces significant increases in hardness, which contributes to improve the wear resistance of the coated parts and components.…”

Fatigue tests under reversed flexure have been conducted on samples of 7075-T6 Al-alloy with the application of electroless Ni-P deposits of thickness ranging from 5 to 50 mm after salt spray corrosion (100, 500 and 1000 hours). The corrosion damage of the coated and uncoated samples was determined through the measurement of the mass loss and surface corroded morphology. The mean microhardness of the high phosphorous (Hi-P) deposits in 5, 25 and 50 mm thickness were found to be 334, 457 and 606 Hv 50 , and the mean surface roughness (Ra) were measured at 0.197, 0.217 and 0.223 mm for 5, 25 and 50 mm thickness, respectively. The salt spray tests revealed that the corrosion damage increases as the exposure time increases for the 5 mm coating. The corrosion damage literally stopped when the coating thickness was increased to 25 mm. The fatigue strength of the coated samples was found decrease slightly as the deposit thickness increases to 25 mm, whereas the reduction on the fatigue strength for the 50 mm deposit is significant. It has been observed that the reduction in the fatigue strength is less or to none for the thicker coating system. For the 5 mm Hi-P deposit sample, the fatigue crack initiation started at the surface corrosion pitting then extending to the substrate and onto failure, this phenomenon reduced the fatigue strength as compared to the uncoated samples. The fatigue strength is decreased slightly as the thickness increases to 25 mm and 50 mm. With or without corrosion damage, the fatigue crack initiation all started from the coating and extended to the substrate through the bonding between the coating and the substrate. Balancing between the need for the corrosion resistance and the fact on the fatigue strength reduction, the optimum coating thickness seems to be greater than 5 mm but less than 25 mm for the aerospace alloy 7075-T6 Al-alloy.
