| Abstract: | The modification of the Si-Cr-Ti slucy refused coating used as the high-tempera-ture oxidation-resistance coatings on 103 niobium alloys is studied,adding reactive elements Zr and inert oxide Y_2O_3 to Si-Cr-Ti Slurry. The proeess parameters of modified method are defined by the experiment.The modified coating has higher oxidation-resistance performances.The microstructure,distribution of elements and the distribution of phases in modified coatings are analysed with modern measuring teehnique. In the endThe oxidation-resistanee meehanisms of various kinds of modified coatings are discussed. |
