【摘要】：將Al粉、Sn粉、SiO_2粉、苯丙乳液、聚乙烯醇和羧甲基纖維素等原料,按照一定配比制備鋁基高溫抗氧化涂層,探討不同熱處理溫度和保溫時(shí)間對(duì)涂層高溫抗氧化性的影響。采用光學(xué)顯微鏡、場(chǎng)發(fā)射掃描電鏡、能譜分析儀和X射線衍射儀研究噴涂和未噴涂表面的微觀形貌、元素?cái)U(kuò)散和相組成。結(jié)果表明,鋁基高溫抗氧化涂層能夠阻止鈦坯在熱加工過(guò)程中產(chǎn)生表面氧化,在過(guò)渡層中形成了具有良好防護(hù)作用的Al2O3-Ti Al相和Ti Al3-Ti相,且較適宜的處理溫度為1050℃保溫時(shí)間為8 h。
[Abstract]:Aluminum based high temperature oxidation resistant coatings were prepared by Al powder Sn powder SiOW powder, styrene-acrylic emulsion, polyvinyl alcohol and carboxymethyl cellulose. The effects of different heat treatment temperature and holding time on the oxidation resistance of the coatings at high temperature were investigated. The microstructure of sprayed and unsprayed surfaces was studied by optical microscope, field emission scanning electron microscope, energy spectrum analyzer and X-ray diffractometer. The results show that Al based high temperature oxidation resistant coating can prevent the surface oxidation of titanium billet during hot working, and the Al2O3-Ti Al and Ti Al3-Ti phases have been formed in the transition layer. The suitable treatment temperature is 1050 鈩，
