英文摘要:

      The advantages and disadvantages of polymer precursor-derived ceramics (PDC) are analyzed. The research progress of high-yield ceramic formation on metallic surfaces via pyrolysis of polymer precursors (such as polysiloxanes, polycarbosilanes and polysilazanes) is reviewed and the problems of this technique are summarized. The paper also describes the future research directions which include exploring new controllable routes for high quality ceramic coating, developing high-ceramic-yield material, concentrating on compound development of pyrolysis material system, and promoting theoretical research on pyrolytic ceramization.
