“…It is exemplified that to facilitate the micro hardness of all heated depositions, it depends mainly on features such as intensity of assimilation of nanoparticles, heating temperature, and steady allocation by way of a smaller quantity of agglomeration of nanoparticles. [6,11,13,[35][36][37][38][39][40][41]. NiP-ZrO2 nanocomposite coating composition is examined using XRD, EDAX, and SEM techniques.…”

“…Further, the triobological properties of tetragonal zirconium (Y-TZP), Al2O3 with MgO, ZrO2 dispersed in Al2O3 (ZTA) and alumina dispersed in Y-TZP (ADZ) revealed that Y-TZP (ADZ) had better wear resistance among all tested materials [34]. The enhanced wear and friction resistance behaviour was found for the conventional and in-situ methods prepared of EL Ni-P-ZrO2-Al2O3 (NiPZA) taking place on aluminum substrates after heating [35]. The similar group investigated the triobological behaviour of electroless Ni-P-ZrO2-Al2O3-Al3Zr depositions scheduled on low-carbon steel, aluminum, and carbon fabric substrates [36].…”

Electroless Synthesis of Nicle phosphate zirconium dioxide (EL NiP/-ZrO2) has been carried out with ZrO2 nanocomposite (50 to 160 nm and concentration 4 gpl) and randomly dispersed into an alkaline Ni-P electroless bath (pH 8.0). The deposited thickness of NiP/-ZrO2 nanocoatings resting on mild steels (MS) substrate (AISI 1040 grade) is carried out to evaluate the surface morphology and elemental composition. The SEM, EDAX and XRD methods elucidated clear difference between Ni-P along with NiP/-ZrO2 nanocomposite coatings. Moreover NiP/-ZrO2 nanocoatings contain uniform burly of ZrO2 nanoparticles like whitish globules. Further the as-coated Ni-P/-ZrO2 nanocoatings revealed mostly amorphous structures, while in heated coatings (temperatures 150, 350, and 550 °C with pure Ar) as temperature rises, the amorphous structure transformed leisurely to crystalline structure. The microhardness values in Vickers-unit of the developed nanocomposite coatings are determined and it is found that for a particular load with increase of temperature microhardness as well as corrosion resistancealso increases.

“…But too long pulse on-time will increase the ratio of deposited metal to adsorb Cu substrate. As a result, the effective inhibition effect is reduced and thus the effect of interfering with grain growth is reduced, which reduces the formation speed of crystal nucleation, causing the grains to become larger; on the other hand, it will lead to interface ion consumption and concentration polarization [43]. Table 4 and figure 5 show the effect of different pulse on-times on the roughness and 3D morphology of the silver coatings, and its further confirmed that the best morphology is achieved at a pulse on-time of 1.2 ms, with relatively smaller roughness.…”

Pulse electroplating technology has the characteristics of fine grain and good corrosion resistance. In order to ensure the good application of electroplated silver cone cavity in solar radiation detector. The effects of three process parameters, including average current density (0.4-1 A/dm2), pulse on-time (0.2-1.8 ms) and pulse off-time (0.8-4.8 ms), on the deposition rate, appearance and corrosion resistance of silver coating were studied by control variates. The surface morphology and composition of silver coatings were studied by scanning electron microscope (SEM), laser confocal microscopy and energy dispersive X-ray spectrometer (EDX). The corrosion resistance of silver coating in 3.5 wt.% NaCl solution was studied by polarisation curves and electrochemical impedance spectroscopy. The results show that pulse electroplating takes advantage of the dynamic change of current to influence the size of deposited particles and the degree of densification of the coating by precisely adjusting the pulse plating parameters, and ultimately obtains the coating with excellent morphology. The optimal parameters are: average current density 0.6 A/dm2, pulse on-time 1.2 ms, pulse off-time 1.8 ms. The silver coating prepared under process conditions has excellent corrosion resistance (7059 Ω/cm2). The surface crystal grain is dense, without obvious defects.

“…[5][6][7][8] So far, various researchers have investigated the role of different factors on erosion wear, including the most recognized and critical erosion influences: particle velocity and impact angle. 9,10 In general, the velocity shows a power-law relationship with the erosion rate, with power exponents ranging from 1.7 to 2.6. 11 For impact angles, ductile materials reach their highest erosion rates at lower angles (15°-30°), while brittle materials reach their highest at 90°normal angles.…”

When studying the erosion behavior of fracturing pipelines, it is inevitable to consider the exacerbating effect of fluctuating internal pressure on pipeline erosion damage. Therefore, an erosion experimental apparatus capable of applying fluctuating tensile loads to specimens was developed to investigate the erosion rate of 35CrMo steel at different average tensile stresses (0–500 MPa), impact angles (15–90°), flow velocity (7.5–20 m/s), and experimental times (10–60 min), and to analyze the erosion damage mechanism under fluctuating loads by observing the microstructure within the erosion scars using scanning electron microscope. The results indicated that erosion rate increased up to 36.84% compared to that without loading under the same erosion condition. Erosion rate increased up to 822.00% when velocity increased from minimum to maximum. Under fluctuating loads, the deepest part of the erosion scar cracked first and the specimen eventually fractured completely along with its entire width, demonstrating that the newly established experimental conditions can well reproduce the sudden bursting phenomenon common to high-pressure pipelines that erode under harsh conditions. The fracture of the specimen shows laminar structure, which is a typical damage feature resulting from the combined effect of a great number of tensile stress cycles and erosion wear.
