“…Then, the powder is sprayed to the surface of the substrate by compressed air to form a protective layer. 39 Cano, et al, 40 sprayed mullite/ZrO 2 coatings on metal and ceramic substrates for the first time, and discussed the heat-treatment methods to promote crystallization and improve the mechanical properties of the flame spraying coatings without cracks. Habib, et al, 41 prepared three Al 2 O 3 /TiO 2 ceramic coatings with different aluminum-titanium ratios by flame spraying, and studied the porosity, phase, mechanical properties, and wear resistance of the ceramic layers.…”

Ceramic coatings have attracted significant attention for anticorrosion application, given the chemical stability. Although many satisfactory results have been achieved, there is no review on the latest research progress of ceramic anticorrosion coatings. For the first time, this paper systematically reviews the lastest advances of ceramic anticorrosion coatings. First, the preparation technologies of ceramic coatings are described in detail. Toughening, as the key to the anticorrosion of ceramic coatings is also highlighted. Besides, the corrosion mechanisms of ceramic coatings are illustrated. The paper is ended with concluding some doubts of ceramic coatings and outlining the trend for future research.

“…Because of factors like easiness of operation as well as being able to build a variety of materials on substrate, one of the most commonly used techniques to modify the surface properties of metal-based materials is thermal spraying. However, there are various limitations associated with the thermal spray technique including porosity and poor mechanical bonding between the splats [5][6][7][8]. The TIG cladding results in metallurgical bonding of the coatings over the substrate but it causes significant geometric dilution due to the high heat input to the substrate [9].…”

In this present study, the Inconel-625 powder was used for the surface modification of SS-304 alloy by utilizing the concept of a hybrid microwave heating technique. The XRD analysis shows the presence of various carbide and Laves phases in addition to a Ni-Cr-Fe-based face-centred-cubic matrix in the modified clad layer. The microstructural analysis revealed that the developed clad was metallurgically bonded with the substrate and free from any interfacial cracks. The modified layer mainly consists of two regions: cellular (matrix) regions and grain boundaries (GBs) regions. The average porosity in the modified clad layer was evaluated to be about 1.65%. The average microhardness (440±45 HV) of the modified clad layer was observed to be about 2.1 times the base metal microhardness (210±10 HV). The clad specimens exhibited a considerably lower wear rate (about 2.8 times less weight loss) than the substrate SS-304 during the dry sliding wear test. The shallow grooves, craters, and material debonding were the typical fracture features associated with the clad surfaces during rubbing when examined under a scanning electron machine apparatus.

“…Thermal spraying is a process in which particles are deposited on a substrate [1][2][3][4][5]. Consequently, the spraying technique is a way of generating a 'stream' of such particles.…”

Thermally sprayed of X30Cr13 martensitic stainless steel coatings are widely used to reduce degradation of components and structures due to mechanical wear. In this paper, the microstructure and mechanical properties of X30Cr13 coated onto on 35CrMo4 using Wire Arc Spray Process (WASP) are investigated. These coatings were made with to different system bond-coat layer which is constituted by Ni-Al. The microstructure characteristics of the coatings are studied using the combined techniques of X-ray diffraction (XRD), scanning electron microscopy (SEM). Measurements of Vickers hardness was carried out on top of the surface of stainless steel. The scanning electron microscopy presents a dense microstructure of this stainless steel, which had a homogeneous compact lamellae shape with the presence of pores and unmelted particles. The wear resistance of the two systems composite Sub/Bond-Coat/X30Cr13 and Sub/X30Cr13 is affected by sliding velocities under different applied loads. The system composite Sub/X30Cr13exhibits low wear resistance than Sub/Bond-Coat/X30Cr13 coating.
