Cemented　carbides　have　enjoyed　widespread　applications　as　a　function　of　their　outstanding　properties　during　the　past　100　years.　Despite　the　advantages,　however,　recently　there　have　been　concerns　about　the　challenges　associated　with　traditional　cemented　carbides,　i.e.　the　conflict　of　properties　(hardness　and　toughness,　strength　and　wear　resistance)　as　well　as　the　instability　of　reliability　in　service,　necessitating　the　development　of　functional　gradient　cemented　carbides　(FGCCs).　Although　recent　decades,　investigations　have　seen　explosive　growth　in　FGCCs,　there　is　still　a　lack　of　comprehensive　review　on　FGCCs.　Herein,　the　current　study　applies　towards　summarize　the　progress　of　FGCCs　during　the　past　60　years,　emphasizing　the　demand　in　FGCCs　with　tailored　properties　and　customized　requirements　for　specific　applications.　We　initially　introduce　basic　cognition　of　FGCCs,　subsequently,　comprehensively　elucidate　the　gradient　formation　mechanisms　of　carburization,　decarburization,　nitridation,　denitrification,　infiltration　process,　and　construction　methods　(solid　-phase　sintering,　graphene　doping　and　additive　manufacturing　etc.),　then　summary　processing　techniques　and　mechanical　properties　of　FGCCs.　In　addition,　the　impart　of　additive　on　further　improving　the　properties　of　FGCCs　is　discussed.　Afterward,　the　possible　applications　of　FGCCs　at　different　areas　are　proposed.　At　the　end　of　this　paper,　a　summary　of　concluding　remarks　and　potential　developed　direction　of　state-of-the-art　FGCCs　is　provided.
