“…This composite coating showed higher oxidation resistance in comparison with steel at 700 and 900uC. 4. The formed oxide scale on the surface of the steel consisted of a thick three oxide layer with a porous structure and large cracking, while the formed oxide layer on the surface of the composite coating was a multiphase oxide layer with lower thickness and no delamination or sizeable cracking.…”

In this study, B 4 C-TiB 2 -TiC-Ni coating was thermally sprayed on the surface of 4130 steel substrate by high velocity oxyfuel (HVOF) torch. Before the HVOF process, the B 4 C-TiB 2 -TiC-Ni powder was prepared by mechanical alloying (MA). In order to study the oxidation behaviour of the coating and 4130 steel, thermogravimetric analysis (TGA) was done. The structural evolution of the samples was investigated by X-ray diffractometry (XRD). The microstructure and elemental analysis of the samples were studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The coating showed higher oxidation resistance in comparison with the 4130 steel at high temperatures. It was also found that the dissolution of oxygen in the coating was the rate determining process of the coating oxidation, creating the quasi-cubic kinetic rate.

“…HVAS is widely used to improve the surface properties of steel components. In China, alloy materials are utilized in over 85% of coatings, with Fe-Ni stainless steel and Fe-Cr stainless steel being particularly prevalent coating materials [12][13][14]. Considering that nickel holds an expensive and strategic status as a metal, there is a critical need to develop novel iron-based alloy coatings, aimed at reducing the use of nickel.…”

This study explores the deposition of an Fe-MnCrSi/TiC coating on 45 steel surfaces using high-velocity arc spraying technology, examining the microstructure and hot corrosion behavior of the resultant layer. The microstructure of the FeMnCrSi/TiC coating primarily consists of an α-Fe (BCC) solid solution, composed of Fe, Mn, Cr, Si, C, and other elements, with a minor presence of β-Fe (FCC) solid-solution phase and unmelted TiC particles. Following 100 h of cyclic 900 °C hot corrosion, Mn on the coating surface preferentially oxidizes, forming a manganese-rich oxide layer. This process reduces the oxygen partial pressure (O2) within the coating, prompting the formation of a dense Cr2O3 layer on the inner side of the oxide layer. Concurrently, the rapid diffusion of Mn and Cr elements triggers the generation of Mn- and Cr-deficient regions at the metal/oxide layer interface, inducing the transformation of the coated metal primary matrix from an FCC + BCC dual phase to an α-Fe (BCC) single phase. After the reaction, the hot corrosion weight gain of the coating reached 12.43 mg/cm2, approximately one-fourteenth of the weight gain of the 45 steel substrates. This weight gain adheres to the parabolic law, suggesting that the FeMnCrSi/TiC coating exhibits excellent corrosion resistance under the given conditions.
