“…Moreover, the measurements of the hardness of the substrate and the coating showed more than twice the hardness value of the nickel coating (1057 ± 13 HV) than the Nimax (426 ± 3) HV steel. The coating hardness is higher than the hardness of Ni–P coating (845 ± 7.6 HV) obtained Samanta et al [ 39 ], although the same electroless method was used. In addition, the hardness of the produced electroless coating is much higher than that of Ni-electroplated coating (560 ± 12.8 HV) obtained by Samanta et al [ 39 ].…”

“…The high hardness of the Ni-P coating also has a protective effect against cavitation erosion [12,16]. A much higher hardness than that obtained by Samanta et al [39] may be due to a lower density of voids and pores, and/or lower grain size. Nevertheless, the differences in the corrosion resistance of the coating and the substrate, as well as the decrease in hardness and modulus of elasticity under cyclic loading conditions, affect the development of damage.…”

In addition, the hardness of the produced electroless coating is much higher than that of Nielectroplated coating (560 ± 12.8 HV) obtained by Samanta et al [39]. Such a high hardness in comparison to the hardness of the Ni-based coatings produced by other methods [30][31][32] may prove the rightness of the selection of the coating application method to obtain high hardness.…”

Damage Development on the Surface of Nickel Coating in the Initial Period of Erosion

The common occurrence of the phenomenon of cavitation in many industries and the multitude of factors affecting the resistance to cavitation erosion of used materials contribute to the search for methods and appropriate parameters of coating application that are able to minimize the effects of erosion. To determine the validity of the developed application parameters and the method used, cavitation studies and microscopic observations of the development of erosion during the cavitation test were carried out. There was a clear lack of incubation time and a linear increase in losses after 60 min of the test. Moreover, the damage observed during the test overlapped, widening the area of erosion and thus leading to damage to the integrity of the coating.

“…One involves the design of steel microstructures with H-traps (carbides and carbonitrides) and the other one involves the application of suitable H-barrier coatings over the steel substrate to prevent H-absorption during service [1,2]. The application of the second group of such H-barrier coatings developed recently [3,4] will be discussed in the present work.…”

The present work discusses very good resistance to hydrogen embrittlement as well as wear resistance of NiP coated API (American Petroleum Institute) X70 steel as compared to the bare steel and electrolytic crystalline Ni coated steel. The NiP coatings with three compositions (hypo, hyper and near-eutectic compositions), prepared by an electroless technique, were predominantly amorphous. The relative wear behavior of the coatings was studied using ball-on disc tests in air. The hydrogen embrittlement susceptibility (HES) was assessed using slow strain rate tensile (SSRT) tests after cathodic hydrogen charging of the coated as well as bare steel. The superior wear resistance of the NiP coated steels showed abrasive wear, whereas the Ni-coated steel showed adhesive wear. Hyper and hypo-eutectic NiP coated steels showed a comparatively lower H-induced embrittlement than the uncoated and Ni-electroplated steels and these could be attributed to the excellent hydrogen barrier property of the NiP coatings.
