英文摘要：

The techniques of making internal ceramic coating by static self-propagating high-temperature synthesis （SHS） method on the thin wall pipe, straight pipe, elbow pipe, tee pipe and double layer pipe were developed. A technology of static-centrifugal SHS was proposed. The possibility of using the ceramic coating as thermal insulation layer in the cylinder or exhaust channels or vent-pipe on engine has been researched. A new semi-solid working mould was developed using SHS coating technique. Details of the coating tests including coating process optimization, hot shock test, the flaw detecting by X- ray and the application experiments on liquid forging of steel and aluminum alloy were carried out. The results show that the ceramic coating on semi-solid forging mould can improve the service life of the mould remarkably.
