Plasma-jet coating of preoxidized XC38 steel: influence of the nature of the oxide layer

Development of conversion coating on mild steel prior to sol gel nanostructured Al2O3 coating for enhancement of corrosion resistance

“…Formation of iron oxides (Fe 2 O 3 /F 3 O 4 /FeO) on steel surface, during thermal and plasma sprayed coatings [14,28], had adversely affected the adhesion of the coating. However, in present conversion coating The electrochemical parameters derived from potentiodynamic polarization curves (Fig.…”

C40E steel oxidation under CO2: Kinetics and reactional mechanism

“…In fact, the origin of the present work was a new process of coating of steel pieces by the way of thermal plasma deposition. It was found that initial sandblasting of the samples (for increasing roughness of the substrates surface before deposit in order to obtain a better coating adhesion) could be replaced favorably by a preoxidation of the substrates, provided that iron monoxide was formed [1]. For obtaining this oxide, one of the classical route is oxidation under CO/CO 2 mixtures [2,3],…”

Modelling of Alumina Splat Solidification on Preheated Steel Substrate Using the Network Simulation Method

“…The interface, which is usually defined by the inverse of the heat transfer coefficient in the interface, called contact thermal resistance, R th , also depends on the absorbates and condensates in the substrate surface and also has an influence on the CR [26][27][28][29][30][31][32][33]. These products can disappear if preheating is applied on the substrate surface before the coating process.…”
