Alumina ceramic strengthening process

- May 30, 2019-

In order to strengthen alumina ceramics and significantly increase their mechanical strength, a new type of alumina ceramic strengthening process has been introduced abroad. The process is novel and simple. The technical method adopted is to apply a layer of silicon compound film on the surface of alumina ceramics by electron beam vacuum coating, sputtering vacuum coating or chemical vapor deposition, and heat at 1200 ° C to 1580 ° C Treatment to toughen alumina ceramics.
