High-Temperature Oxidation Behavior of NiCoCrAlY Coatings Deposited by Laser Cladding on 304 Stainless Steel

Mechanical, morphological, and corrosion features of Ni–Cr oxide nanocomposite coating deposited on SS304 by EPD

“…2,12,13 Green particles of Cr 2 O 3 with antibacterial features, chemical stability, thermal stability, and high hardness are used in medical fields, improving the corrosion properties of metals at high temperatures and forming wear-resistant coatings in dry and wet environments. [13][14][15][16][17] Moreover, due to its low-friction coefficient, Cr oxide is used in the formation of self-lubricating coatings in order to reduce the wear rate. [18][19][20] Ni and Cr oxide nanoparticles interact with bacteria by releasing Ni 2+ and Cr 3+ ions to interrupt or hinder the growth of bacteria.…”

“…9,[27][28][29][30] However, their vulnerability in intense oxidizing environments and lack of tailored performance in the hospital environment due to the growth of all kinds of bacteria are considered serious problems. 17,[31][32][33] Therefore, surfaceengineering researchers have tried coatings with different chemical compositions and structures on the steel surface and shared their results. For example, Movassagh-Alanagh et al developed Ti/TiN/TiSiN multilayer coating on SS304, which increased wear and corrosion resistance.…”

“…Moreover, the chemical stability of NiO particles has caused it to be a suitable inhibitor to prevent the substrate reaction with the surrounding environment in coating applications 2,12,13 . Green particles of Cr 2 O 3 with antibacterial features, chemical stability, thermal stability, and high hardness are used in medical fields, improving the corrosion properties of metals at high temperatures and forming wear‐resistant coatings in dry and wet environments 13–17 . Moreover, due to its low‐friction coefficient, Cr oxide is used in the formation of self‐lubricating coatings in order to reduce the wear rate 18–20 .…”

“…The appropriate corrosion and wear resistance of 304 stainless steel (SS304), along with other excellent functional properties and its reasonable price, are the primary reasons for its widespread use in industries 9,27–30 . However, their vulnerability in intense oxidizing environments and lack of tailored performance in the hospital environment due to the growth of all kinds of bacteria are considered serious problems 17,31–33 . Therefore, surface‐engineering researchers have tried coatings with different chemical compositions and structures on the steel surface and shared their results.…”
