“…The substrate coated with Cr3C2-25%NiCr showed highest volumetric erosion at 90°angle of impingement, with reduction at 60°and became minimum 45°in agreement with findings of Vicenzi [35] and Hawthorne et al [36]. Likewise, Al2O3-13%TiO2 coated substrate showed the similar behaviour of brittle materials in accordance with the results reported by Wang et al [37] and Matikainen et al [38]. Therefore, at impingement angles of 45°.…”

WC-12%Co, Cr 3 C 2 -25%NiCr, 80%Ni-20%Cr, 87%Al 2 O 3 -13%TiO 2 coatings were deposited by Air Plasma Spray (APS) technique on ASTM A36 steel. Erosion behaviour of sprayed coated samples were investigated at three different impact angles (45°, 60°and 90°). The mechanism of erosion was investigated on uncoated and coated samples. The rate of erosion of the substrate first increased with increasing angle of impact and then gradually decreased. But the erosion rate of the coated samples increased steadily. Substrate shows the higher metal removal whereas coating shows the higher erosion resistance. WC-12%Co coated samples performed well in erosion testing and offered best erosion resistance as compared to the substrate and all other coatings. Ductile fracture takes place on substrate material at higher impact angle. Overall, all the coated samples have shown less erosion propensity when compare to the bare one.

“…Due to the combination of wear-, oxidationand aggressive environments-resistance, the application of such coatings could protect parts working under severe conditions [11,[20][21][22][23][24]. Although papers report promising results regarding application of APS titaniaalumina based coatings for improvement of cavitation erosion resistance (CER) [18,25], it seems that influence of spray parameters has not been completely investigated. In the industrial applications, the selection of basic APS process parameters (i.e.…”

In this paper the results of cavitation erosion test of ceramic coatings are presented. The Al2O3-13% TiO2 coatings were manufactured by powder atmospheric plasma spraying. The plasma spray experimental parameters included two variables: (i) spray distance varying from 80 to 100 mm and (ii) torch linear speed varying from 300 to 500 mm/s.The as sprayed surface roughness was measured. The coatings structure was investigated using SEM. Porosity was investigated according to the ASTM E2109-01 Standard procedure. Additional microhardness measurements were conducted. The cavitation tests were carried out on vibratory test rig according to the ASTM G-32 standard regarding to the stainless steel (grade 304) reference sample. The cavitational worn areas were examined using SEM microscopy and roughness measurements. The influence of coatings microstructure and microhardness on the cavitation erosion resistance was investigated. The coatings microstructure was strongly dependent on spray distance as well as torch linear velocity. Decrease of the hardness was a result of less compact structure and lower degree of well molten particle. On the contrary, the best cavitation erosion resistance was characteristic for coatings which have quite good and compact structure but on the other hand the heat flux was lower. Higher heat flux caused thermal stresses, which were visible as cracks in the structure. Moreover, the type of the structure was important because from the point of view of the cavitation erosion resistance, lamellar architecture is more preferred than the columnar one. Finally, the structure type was linked to the process parameters.

“…Thermally sprayed coatings are often used to increase the resistance of the parent material against corrosion and wear [3][4][5][6][7][8][9][10][11][12][13][14][15]. The desired properties of coatings applied by the high-velocity oxygen fuel (HVOF) method also include high density and good adhesion, which are characterized by the ability to form coatings with a small portion of oxides and phase transformations [16][17][18][19].…”

The paper is focused on investigating the quality of two grades of thermally sprayed coatings deposited by high-velocity oxygen fuel (HVOF) technology. One grade contains WC hard particles in an environmentally progressive Ni-and Co-free FeCrAl matrix, while the second coating contains WC and WB hard particles in a cobalt matrix. The aim of the experimental work was to determine the effect of thermal cyclic loading on the coatings' resistance to adhesive, abrasive and erosive wear. Abrasive wear was evaluated using abrasive cloth of two grit sizes, and erosive wear was evaluated by a dry-pot wear test in a pin mill at two sample angles. Adhesion wear resistance of the coatings was determined by a sliding wear test under dry friction conditions and in a 1 mol water solution of NaCl. Corrosion resistance of the coatings was evaluated using potentiodynamic polarization tests. Metallographic cross-sections were used for measurement of the microhardness and thickness and for line energy-dispersive X-ray (EDX) analysis. The tests proved the excellent resistance of both coatings against adhesive, abrasive, and erosive wear, as well as the ability of the WC-WB-Co coating to withstand alternating temperatures of up to 600 • C. The "green carbide" coating (WC-FeCrAl) can be recommended as an environmentally friendly replacement for Ni-and Co-containing coatings, but its operating temperature is strictly limited to 500 • C in air.
