Oxidation of Stainless Steel in the High Velocity Oxy-Fuel Process

Isothermal Oxidation Behavior of Plasma Sprayed MCrAlY Coatings

“…A typical example is the improvment of wear resistance (Neiser et al, 1998). The deposited oxides increase also the hardness of the coating (Dobler et al, 2000). Therefore, it is important to understand the oxidizing behavior of spray materials at spraying.…”

“…The oxide content in the as-sprayed coating depends on the spraying technique, spraying parameters and starting material compositions (Dobler et al, 2000). Espie et al reported that the oxygen content in plasma sprayed low carbon steel particles increased with spray distance (Espie et al, 2001).…”

Oxidation behaviour of ferritic stainless steel grade Crofer 22 APU at 700 °C in flowing Ar−75%CO2−12%H2O

“…The formed inner oxide layer dissolved in the water as ferrous ions with higher concentration of H 2 O and dissolved ferrous ions precipitated as Fe 3 O 4 particles at the surface of the inner oxide layer because of the oxidation of ferrous ions. Part of the precipitated Fe 3 O 4 particles oxidized into Fe 2 O 3 and as a result, the hematite particles and magnetite particles became mixed with high concentration of H 2 O [19].…”

Development of Sustainable Cold Spray Coatings and 3D Additive Manufacturing Components for Repair/Manufacturing Applications: A Critical Review

“…Table 1. Applications and properties of cold spray coating materials [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

“…For many materials, however, the use of high process temperature causes coatings to be internally-fractured due to decarburization, dissolution, and delamination at least [14]. For oxygen-sensitive materials for instance it is often required to produce coatings in an expensive vacuum chamber, thus limiting broader penetration of thermal spray into many commercial applications [15][16][17][18]. Traditional thermal spray processes are often found inadequate to use for temperature-sensitive materials and applications where coatings are required for repair/manufacturing with thickness of a few millimeters.…”
