High-performance Cr2AlC MAX phase coatings: Oxidation mechanisms in the 900–1100°C temperature range

Cyclic oxidation behavior and oxide scale adhesion of Al/NiCrAlY coating on pure titanium alloy

Mo-Si-B/Al2O3 composite coating was applied to Nb-Si based alloys by plasma spray-physical vapor deposition (PS-PVD) followed by spark plasma sintering (SPS). Interdiffusion behavior of the coating at 1200, 1250 and 1300 °C in dry air was investigated. The results indicate that the thickness of the interdiffusion zone (IDZ) in the composite coating is smaller than that in the Al2O3-free coating. The Al2O3 diffusion barrier effectively restrains coating-substrate interdiffusion. The activation energy for IDZ growth is increased to 367 kJ/mol correspondingly, and the interdiffusion coefficient of Si is decreased by one order of magnitude.

Interdiffusion behavior of Mo-Si-B/Al2O3 composite coating on Nb-Si based alloy

A Ni-Re film was electroplated as a diffusion barrier between the Ni-Al coating and the iron alloy substrate. The interdiffusion between the coating and the substrate was investigated by micro-structure analysis, and the interdiffusion coefficient was calculated using Boltzmann-Matano method. The results indicated that the Ni-Re interlayer played a superior barrier effect, almost fully blocking interdiffusion and retarding the formation of diffusion zone (DZ). The Ni-Al coating without a diffusion barrier showed severe carburization corrosion in the diffusion zone during carburization process, while the Ni-Al coating with the Ni-Re diffusion barrier effectively protected the steel substrate from carbon attack.

Thermal stability and mechanical properties of cold-sprayed Nickel-Yttria coating

This work deals with a double-layer coating for the corrosion protection of stainless steel (SS) structures used in molten fluoride salt reactors for energy production. It aims to mitigate the dissolution of chromium from stainless steel structures into the molten salts. On 304SS substrates, three coating layers consisting of NiCoCrAlY, Ni(O), and the nickel layer on the top were deposited by cold spraying. The Ni(O) coating was made by using a powder containing active oxygen and prepared by mechanical-alloyed pure Ni powders in ambient atmosphere. The Al 2 O 3 diffusion barrier was evolved by annealing the cold-sprayed coating system in argon at temperatures ranging from 800 to 1000 °C at the interface between NiCoCrAlY and Ni(O) layers. During the annealing, the Al 2 O 3 layer formed with a growth following a parabolic law, resulting from the reaction of the oxygen in the Ni (O) layer with the aluminium in the NiCoCrAlY layer. The coating test conducted at 900 °C for 100 h in argon showed that the Al 2 O 3 layer changed little during annealing and could effectively prevent the diffusion of Fe and Cr from the SS substrate to the upper Ni layer.
