Tungsten carbide saizi ya tirigu

Mtundu uwu wa alloy umatchedwa YG mtundu wa alloy.Kapangidwe kabwino ka WC-Co aloyi yoyera ndi aloyi yamitundu iwiri yopangidwa ndi polygonal WC gawo ndi gawo lolumikizana Co. Nthawi zina zosakwana 2% za ena (tantalum, niobium, chromium, vanadium)carbidesamawonjezeredwa ngati zowonjezera pamasamba odulira kapena kujambula kufa kuti awonjezere moyo wautumiki wa chida.Komabe, izi sizisintha magwiridwe antchito a aloyi, ndipo akadali amtundu wa WC-Co wa carbide yopangidwa ndi simenti.Poyerekeza ndi ma carbides ena opangidwa ndi cobalt omwe ali ndi cobalt, mtundu uwu wa aloyi umakhala ndi mphamvu zosunthika kwambiri, mphamvu zopondereza, kulimba kwamphamvu ndi zotanuka modulus, komanso kagawo kakang'ono kamene kamakulitsa.

Malinga nditungsten carbidembewu, mtundu uwu wa simenti carbide zambiri amagawidwa m'magulu atatu: coarse njere, sing'anga tirigu ndi mbewu zabwino.Ndi chitukuko cha kukonzedwa zipangizo ndisimenti carbidenjira zopangira, njere za WC za ma aloyi a WC-Co zakula kwambiri mpaka kumalekezero owopsa komanso abwino kwambiri.
