Rudzi urwu rwealloy inonzi YG type alloy.The normal structure yeWC-Co alloy white is two-phase alloy inoumbwa nepolygonal WC phase uye bonding phase Co. Dzimwe nguva isingasviki 2% yezvimwe (tantalum, niobium, chromium, vanadium)carbideszvinowedzerwa sezvinowedzera kune blade yekucheka kana kudhirowa kufa kuti uwedzere hupenyu hwesevhisi yechishandiso.Nekudaro, izvi hazvichinje kuita kwekutanga kweiyo alloy, uye ichiri yeWC-Co mhando yecemented carbide.Kuenzaniswa nemamwe simende carbides ane yakafanana cobalt zvirimo, iyi mhando yealloy ine yakanyanya kuchinjika simba, kudzvanya simba, kukanganisa kuoma uye elastic modulus, pamwe nediki mutsara wekuwedzera coefficient.
Maererano netungsten carbidezviyo, rudzi urwu rwecemented carbide rinowanzopatsanurwa muzvikamu zvitatu: coarse grain, medium grain and fine grain.Nekugadzirwa kwezvinhu zvakagadzirwa uyesimende carbidemaitiro ekugadzira, iwo WC tsanga dzeWC-Co alloys dzakakura zvakanyanya kune yekupedzisira-yakaomarara uye yekupedzisira-yakanaka magumo.
