摘要: Abstract A study on the effect of SUS316L stainless steel surface conditions wetting behavior molten multi-component oxides ceramic was performed and aimed to contribute further understanding application in penetration treatment coatings deposition cermet coatings. The results show that at 1273 K, different pre-treatments (polishing heating) had an important behavior. showed good wettability both substrates, however, process polished substrate significantly slower than heated substrates. mechanism interfacial reactions discussed based microscopic thermodynamic analysis, substrates reacted with oxygen generated from decomposition contained argon atmosphere, oxide film caused spread surfaces. For substrate, more time required for oxidation reach composition Heated-S, which resulted relatively slow spreading rates. Moreover, variance roughness drove final contact angles slightly values following sequence Polished-S > Heated-S.
