Advanced ceramic coatings have been largely used in several industrial fields such as aerospace, automotive, power generation, medical or petrochemical, in order to protect or functionalise the surface of different materials. In modern industries, thermal spray processes are the most used ones to manufacture advanced ceramic coatings due to their cost advantages, flexibility and efficiency in processing ceramic materials, especially those with high melting temperature. This chapter provides a brief overview of the progress and current state of different thermal sprayed ceramics and summarises the future trend in this field. Therefore, various advanced ceramics, such as yttria-stabilised zirconia, alumina, hydroxyapatite and bioactive glasses, have been selected for analysis and discussion.

“…Researchers have made significant efforts to enhance the properties of solid lubrication coatings. Specifically, graphite [10,11], molybdenum disulphide [12,13], and metal oxide [14–17] have been studied as wear-resistant materials to improve the coating's friction and wear resistance. In their study, Da et al infiltrated polytetrafluoroethylene (PTFE) into CBC by vacuum impregnation by vacuum impregnation as a reinforcing material.…”

Solid lubricating coatings were applied onto Carbon Fibre Reinforced Polymer (CFRP) substrates, using epoxy resin as the adhesive agent, graphite (C) and molybdenum disulphide (MoS2) as lubricating components, and alumina (Al 2 O 3 ) as the functional filler. The test parts were prepared by spraying technology and co-curing process. The mechanical properties of the coating were evaluated using Bar hardness and wear rate tests, while the microstructure of the coating was analysed using EDS elemental analysis technology. The test results revealed that the filler content had a significant impact on the mechanical properties. The performance of the coating was determined by the formation of a lubricating film, which resulted from the accumulation of lubricant and reinforcing material during external friction. Scheme T7 yielded the best coating performance with a ratio of epoxy resin to molybdenum disulphide to graphite to alumina of 20:8:3:2.

“…The essence of air-plasma spraying is [24][25][26] that powder particles pass through a zone of ionized gas (plasma) formed by an electric gas discharge, are melted, and deposited on the substrate surface heated in the contact zone in the course of coating formation. The main element of technological equipment is a plasmatron that combines the functions of a plasma source and atomizer of disperse material.…”

The operation modes of a plasmatron for powder coating spraying have been studied. The plasmatron has a node of annular input and a gasdynamic focusing of the powder, and the outlet holes of the nozzle-anode are made in the form of rectangular narrowing-expanding channels (No.34334 RK: IPC H05H 1/42). The dynamics and trajectories of the powder particles in the plasmatron were investigated. The paper analyzes the influence of plasmatron arc current and working gas flow rate on the structure and properties of the obtained coatings. It is established that the phase composition of the sprayed coatings and the initial powder is the same: the main phase is the compound TiN, in addition, the structure contains the phase TiO2. The results of tribological tests of the coatings under dry friction conditions according to the ball-on-disk scheme are presented. Within the framework of this study, it can be said, from the point of view of obtaining denser coatings with high performance characteristics, that the optimal modes of plasma spraying of TiN powder are a current of 250 A and the working gas flow rate of argon 34 L/min.
