Press to deposit the first TiN layer 5~7 minutes in Ti layer on surface of metal under -75~-95V, then passing to nitrogen makes pressure rise to 4Pa,
The second TiN layer, sedimentation time 3.2~4.6 minutes, so as to be prepared into cushion are deposited in the first TiN layer；
（4）It is prepared by enhancement layer：TiAl alloy target, TiCo alloys targets are separately turned on, electrical current is 4~6A, bias -90~-
120V, depositing Ti AlN individual layers when circular saw blade substrate turns to TiAl alloy target, circular saw blade substrate deposit when turning to TiCo alloys targets
TiCoN individual layers, so that TiAlN individual layers form enhancement layer with TiCoN individual layers alternating deposit, sedimentation time is 14~18 minutes；
（5）It is prepared by wearing layer：TiAlCo alloys targets are opened, electrical current is 7~9A, -124~-136V is biased, in annular saw chip base
Depositing Ti AlCoN layers on body, sedimentation time are 14~16 minutes；
（6）By step（5）Saw blade after processing is placed in soaking and washing in above-mentioned nonionic surfactant solution and divulged information dry
It is dry.
6. the preparation method of the multi-layer composite coatings according to claim 5 for improving saw blade cutting speed, its feature exist
