“…The similar results were also reported in those previous studies [18,19]. Mohanty et al [20] observed the transformation of Cr 3 C 2 phase to Cr 23 C 6 phase while spraying Cr 3 C 2 -NiCr powder by Jet Kote technique. However, this transformation was not found in this study.…”

“…Due to the characteristics of thermally sprayed coatings, the cracks parallel to the coating-substrate interface are easier to be formed in comparison with those in the perpendicular direction [26]. It results from the elongated nature of the splats and the residual stress fields presented [20]. The length of crack c, from the center to the indent, was used for determining the fracture toughness of the coatings.…”

Abstract:In this work, the Cr 3 C 2 -25% NiCr powder was deposited on stainless steel with different combustion pressures and powder feed rates using HVOF technique. The microstructure, porosity, micro-hardness, indentation fracture toughness, adhesion strength, and wear resistance at 500 • C of the coatings were investigated. The results showed that HVOF sprayed Cr 3 C 2 -25% NiCr coatings possessed low porosity, high micro-hardness, and enough adhesion strength. The powder feed rate had obvious effect on porosity, micro-hardness and indention fracture toughness of the coatings, and the coating sprayed under the powder feed rate of 33.5 g/min possessed the optimal performance. The wear tests illustrated that the HVOF sprayed Cr 3 C 2 -25NiCr coating possessed good wear resistance at the temperature of 500 • C, in which the coating sprayed at the powder feed rate of 33.5 g/min had the best wear resistance due to its dense structure and enough fracture toughness.

“…Plasma sprayed coatings have been widely applied in industrial components in several industries [2,3] in a wide range of functionalities and engineering designs such as in free standing or near net shape parts [4,5], environmental clean alternative [6], protection of nuclear equipment [7], and medical purposes [8,9]. One of the most important and widely used applications of plasma spray coatings is their use as wear resistant coatings [10][11][12][13][14].…”

Solid particle erosion (SPE) tests are carried out to evaluate the performance of plasma sprayed coatings of borosilicate glass microspheres (BGM) premixed with Al 2 O 3 particles on metallic substrates. For this purpose, an Air Jet Erosion test rig confirming to ASTM G 76 test standards is used. Relative influence of different operating parameters on erosion rate is assessed by statistical analysis of the experimental findings that are based on Taguchi's L 16 orthogonal array. This analysis helps to identify the most significant factor affecting the erosion wear rate of the coating. The study reveals that the impact velocity, impingement angle, erodent size, and Al 2 O 3 content in the feed stock, in the declining sequence, are the significant factors influencing the wear rate of these coatings. An Artificial Neural Network (ANN) approach is then implemented taking into account training and test procedure to predict the triboperformance of these coatings under wear conditions beyond the experimental range. Further, the microstructural features of the eroded samples are studied from SEM images to identify possible wear mechanisms.

“…In most high temperature coating processes, complex chemical transformations take place during the coating and cooling stages. Transformations such as, interactions between the carbide reinforcement and the matrix [16][17][18] ; decarburization of WC followed by formation of undesirable W 2 C (due to the high flame temperature and oxidizing atmosphere) and transformation of Cr 3 C 2 , as shown, due to the reactive atmosphere within the flame 19 .…”

Erosion-oxidation behavior of thermal sprayed Ni20Cr alloy and WC and Cr3C2 cermet coatings

2005

View full text Add to dashboard Cite

An apparatus to conduct high temperature erosion-oxidation studies up to 850 °C and with particle impact velocities up to 15 m.s -1 was designed and constructed in the Corrosion Laboratories of IPEN. The erosion-oxidation behavior of high velocity oxy fuel (HVOF) sprayed alloy and cermet coatings of Ni20Cr, WC 20Cr7Ni and Cr 3 C 2 Ni20Cr on a steel substrate has been studied. Details of this apparatus and the erosion-oxidation behavior of these coatings are presented and discussed.The erosion-oxidation behavior of HVOF coated Cr 3 C 2 25(Ni20Cr) was better than that of WC 20Cr7Ni, and the erosion-oxidation regimes have been identified for these coatings at particle impact velocity of 3.5 m.s -1 , impact angle of 90° and temperatures in the range 500 to 850 °C.
