“…[1][2][3][4][5] Generally, thermal spraying techniques frequently used for depositing nickel based alloy coatings include arc spraying, high velocity oxygen fuel (HVOF) spraying, plasma spraying and flame spraying. [5][6][7][8][9] However, the HVOF spraying is capable of preparing coatings with lower porosity, less decarburisation, lower oxide content, higher hardness and superior bond strength than many other thermal spraying methods due to the lower operating temperature and higher velocity. [10][11][12] A large number of researches have reported on HVOF sprayed nickel based alloy coatings.…”

“…Carrasquero et al found excellent fretting wear resistance in an HVOF Ni-Cr based alloy deposited on SAE 1045 steel in comparison to the uncoated substrate. 6 Guilemany et al demonstrated the superior erosion-corrosion properties of nickel based HVOF sprayed coating for protecting steel exchanger pipes against the erosion produced by the impact of the ashes in flue gas. 7 Sidhu et al showed that the HVOF sprayed NiCrBSi coating has better hot corrosion resistance than that of Fe based superalloys in a molten salt (Na 2 SO 4 -60V 2 O 5 ) environment at 900uC.…”

In this work, the cavitation silt erosion behaviour and the mechanisms of high velocity oxygen fuel sprayed nickel based alloy coatings under different sediment concentration conditions were studied. The coating with low porosity of 0?88¡0?06% consists of c-Ni, Ni 3 B, Cr 23 C 6 , Cr 7 C 3 and WC phases. The mass loss and mass loss rate of the coatings are found to increase with sediment concentration increasing as a result of more interaction between sand particles and specimen. For the coating in 0 kg m 23 solution, crater and lip are observed on the eroded surface. For the coating in 20 kg m 23 solution, signatures of crater and microcutting are observed. When the sediment concentration rises up to 40 kg m 23 , a process of crater and microcutting first, followed by ploughing and microcutting, is observed. The results suggested that the cavitation silt erosion mechanism for the coating is a ductile erosion mode.

“…Furthermore, the Al2O3 layer becomes thicker with the increase in corrosion time, and Ecorr increases from −0.6~−0.4 V. In reported literature, the Ecorr occurs at −0.6~−0.7 V. However, the Ecorr decreases to −0.7 V as the corrosion increases. The jcorr increases towards a higher current density with corrosion time increasing, as shown in Figure 8 [26][27][28][29]. The Inconel 625 thermal spray coating for the Tafel analysis shows the most positive E corr and j corr among the three coatings.…”

Thermal Spray Coatings of Al, ZnAl and Inconel 625 Alloys on SS304L for Anti-Saline Corrosion

Stainless steel 304L (SS304L) has been selected as the material for canisters for spent fuel storage from three nuclear power plants in Taiwan. A crucial issue is extending the spent fuel storage safety standards of the canisters. The anti-saline corrosion abilities of three thermal spray coatings (i.e., Al, ZnAl, and 625 Inconel alloys) on the SS304L were evaluated by immersion in 3.5 wt % aqueous NaCl and with 0.025 g/cm2 NaCl deposition at 80 °C and 80% relative humidity (RH) for 1000 h. The pristine thermal spray coatings were examined using the pull-off adhesion test to understand the adhesion strength, and Vickers hardness was measured for the mechanical properties of the three coatings. Confocal laser scanning microscopy (CLSM) was used to identify the porosities of the coatings. Furthermore, the surfaces of the specimens before and after corrosion were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS). The composition and distribution of the oxide layers formed on the coating surfaces during corrosion were evaluated. Electrochemical measurement was also performed with the polarization method to quantify the corrosion property of the three thermal spray coatings. The results showed that the corrosion rate of Al coating was lowest from the Tafel analysis after the 1000 h corrosion test in 3.5% aqueous NaCl. In contrast, the corrosion rate of Inconel 625 was lowest after 1000 h of the NaCl deposition corrosion test in a controlled environment. Therefore, the ZnAl thermal spray coating is a potential protection layer, keeping in mind economic considerations, of SS304L for anti-corrosion in saline environments.

HVOF thermal spray process produces coatings with low porosity and low oxide content, as well as high substrate adhesion. Small variations on the parameters of the HVOF process can generate coatings with different characteristics and properties, which also is chemical composition depended of the alloy. FeMnCrSi alloy is a cavitation resistant class of material with a great potential for HVOF deposition use. The main goal of this article is to study the influence of some HVOF parameters deposition, as standoff distance, powder feed rate and carrier gas pressure on three different alloys. FeMnCrSi experimental alloys with some variations in nickel and boron content were studied. Taguchi experimental design with L9 orthogonal array was used in this work. Porosity, oxide content, tensile adhesion strength and microhardness of the coatings were evaluated. The results indicated that all factors have significant influence on these properties. Chemical composition of the alloys was the most important factor, followed by the carrier gas pressure, standoff distance and powder feed rate. The addition of Ni, produces coatings with lower levels of oxide content and porosity. An experiment with improved parameters was conducted, and a great improvement on the coating properties was observed.
