动态过程钢坯高温防氧化涂层及其作用机理探索的中期报告摘要：本报告介绍了钢坯高温防氧化涂层的研究进展，重点探讨了静态涂层与动态涂层在高温环境下的防氧化效果。通过对热处理试件进行SEM、XRD等分析，在不同温度下和不同涂层条件下的表面形貌、相组成和防氧化性能进行了研究。结果表明，动态涂层在高温下具有优异的防氧化性能，这与涂层能够快速生成氧化物薄膜并形成稳定的氧化界面有关。本文还对动态涂层的作用机理进行了初步探讨，并提出了进一步深入研究的思路和方向。关键词：钢坯；高温防氧化涂层；动态涂层；作用机理Abstract:Thisreportintroducestheresearchprogressofhightemperatureanti-oxidationcoatingsforsteelbillets,focusingontheanti-oxidationeffectofstaticcoatingsanddynamiccoatingsinhightemperatureenvironment.Thesurfacemorphology,phasecompositionandanti-oxidationpropertiesoftheheat-treatedspecimensunderdifferenttemperaturesandcoatingconditionswerestudiedbySEM,XRDandotheranalysismethods.Theresultsshowthatthedynamiccoatinghasexcellentanti-oxidationperformanceathightemperature,whichisrelatedtotheabilityofthecoatingtoquicklygenerateoxidefilmandformastableoxidationinterface.Thispaperalsopreliminarilydiscussestheactionmechanismofdynamiccoating,andputsforwardtheideasanddirectionsforfurtherresearch.Keywords:steelbillet;hightemperatureanti-oxidationcoating;dynamiccoating;actionmechanism.
