The　sintering　densification　process　of　(Ti,W,Mo,Ta,Nb,Zr)(C,N)-(Co,Ni)　based　cermet　was　studied.　The　effects　of　sintering　process　on　composition,　microstructure　and　properties　were　discussed.　The　results　show　that　during　the　densification　process　of　(Ti,W,Mo,Ta,Nb,Zr)(C,N)-(Co,Ni)　based　cermets,　the　mass　loss　caused　by　sintering　basically　ends　at　the　solid　phase　sintering　stage.　When　the　sintering　temperature　is　above　1340　degrees　C,　the　volume　shrinkage　and　density　of　the　alloy　increase　sharply　due　to　the　appearance　of　liquid　phase.　The　change　of　nitrogen　content　in　cermet　during　the　sintering　process　is　consistent　with　the　change　of　magnetic　properties　of　the　alloy,　and　the　nitrogen　content　has　a　significant　effect　on　the　formation　of　solid　solution.　When　the　sintering　temperature　is　1490　degrees　C,　the　comprehensive　mechanical　properties　of　(Ti,W,Mo,Ta,Nb,Zr)(C,N)-(Co,Ni)　based　cermets　are　the　best,　and　the　strength　and　toughness　of　the　cermets　can　be　further　improved　by　the　appropriate　control　of　N-2　partial　pressure　at　sintering　temperature.
