摘要
In this study, Fe-W2B-based composite coating on the inner surface of a steel pipe was produced by centrifugal-Self-propagating high-temperature synthesis (SHS) process. There were FeWO4, B2O3, and Al powders as the major reactants. The effects of coupled additives X(Fe2O3-Al) of X = 1, 3, and 5 molar ratio on morphology, composition and micro-hardness of the obtained composite coatings were investigated. The results showed that the system of X = 1 mole was the optimum condition due to its reasonable smoothness (6.5 mu m) and hardest (727.90 and 1170.71HV on alloy and ceramic layers, respectively).
