“…Meanwhile, with the development of thermal spray technology, Fe-based amorphous materials are quickly introduced into the field of surface engineering [1,2]. For improvement on Fe-based amorphous coatings performance, different kinds of methods were developed such as technology improvement [3], parameter optimization [4], hard phase reinforcement [5], and pre/post-treatment [6,7]. Most methods pay attention to the microstructures of Fe-based amorphous coatings such as density and hard phase composition.…”

“…Another method for synchronization of spraying and peening is to mix hard particles into sprayed particles, where hard particles have effects on shot peening. Liang et al [5] mixed Al 2 O 3 particles into Fe-based amorphous powders and prepared an amorphous coating by HVOF. In the research, Al 2 O 3 particles were used as shot peening to induce compressive residual stress.…”

Shot peening was used synchronously to improve Fe-based amorphous coating performance by delivering ZrO2 ceramic particles into a low-temperature region of a flame during the high velocity oxygen flame (HVOF) spray process. The coating became denser, and its hardness became higher via the new process. Moreover, the compressive residual stress was induced by shot peening. The results from the dry friction test indicated that the coating’s wear resistance was enhanced obviously. The wear mechanism of coatings with and without shot peening is an abrasive wear combined with an oxidation wear at wear test conditions of a low load and a low frequency. The coating with the best wear resistance did not have the strongest microhardness but had the highest compressive residual stress. The compressive residual stress had a significant positive influence on the wear resistance at a low frequency, while its effect is weakened at a high frequency.

“…The nanomaterial has a large interface, therefore the atomic arrangement of the interface is quite chaotic, and the atoms are easy to migrate under the condition of external force deformation. Therefore, it exhibits excellent toughness and certain ductility, which makes the ceramic material have novel mechanical properties [85,86].…”

Nano-coating has been a hot issue in recent years. It has good volume effect and surface effect, and can effectively improve the mechanical properties, corrosion resistance and wear resistance of the coatings. It is important to improve the wear resistance of the material surface. The successful preparation of nano-coatings directly affects the application of nano-coatings. Firstly, the preparation methods of conventional surface coatings such as chemical vapor deposition and physical vapor deposition, as well as the newly developed surface coating preparation methods such as sol-gel method, laser cladding and thermal spraying are reviewed in detail. The preparation principle, advantages and disadvantages and the application of each preparation method in nano-coating are analyzed and summarized. Secondly, the types of nano-coating materials are summarized and analyzed by inorganic/inorganic nanomaterial coatings and organic/inorganic nanomaterial coatings, and their research progress is summarized. Finally, the wear-resistant mechanism of nano-coatings is revealed from three aspects: grain refinement, phase transformation toughening mechanism and nano-effects. The application prospects of nano-coatings and the development potential combined with 3D technology are prospected.

“…The short spray distance ensures that the particles collide in the molten state, resulting in a compact structure, 42 while long spraying distance will thicken the coating, reducing the cohesion and residual stress of the coatings. [43][44] For general flame spraying, the spraying speed is limited, and the prepared coatings usually have large grain size as well as cracks. Therefore, scientists have proposed a high velocity oxy-fuel spraying (HVOF) technology.…”

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.
