Zvakanakira, zvazvakaipira, uye mutsauko pakati pesimbi inomhanya-mhanya uye simende carbide.
1. Simbi inomhanya-mhanya:
Simbi inomhanya yakakwira-kabhoni uye yakakwira-alloy simbi. Zvinoenderana nemakemikari ekuumbwa, anogona kukamurwa kuita tungsten akateedzana uye molybdenum akateedzana simbi, uye zvinoenderana nekucheka mashandiro, inogona kupatsanurwa kuita yakajairwa-yepamusoro simbi uye yakakwirira-inoshanda simbi inomhanya. Simbi yepamusoro-soro inofanira kusimbiswa nekurapa kwekupisa. Mumamiriro ekudzimwa, iyo simbi, chromium, chikamu che tungsten, uye kabhoni mune yakakwirira-kumhanya simbi fomu yakanyanya kuoma carbides, iyo inogona kuvandudza kupfeka kuramba kwesimbi (kuoma kunogona kusvika HRC64-68).
Chimwe chikamu che tungsten chinonyungudutswa mumatrix uye chinowedzera kuoma kwakatsvuka kwesimbi. Kuoma kwakatsvuka kwesimbi yepamusoro-soro kunogona kusvika 650 degrees. Simbi yepamusoro-soro ine simba rakanaka uye kuoma. Mushure mekurodza, kuchekwa kunopinza uye hutano hwakagadzikana. Inowanzo shandiswa kugadzira midziyo midiki, yakaoma-yakaumbwa.
2. Cemented carbide:
Cemented carbide inonzi micron-order refractory high-hardness metal carbide powder, iyo inogadzirwa nekupfurwa nekushisa kwepamusoro uye high pressure ine cobalt, molybdenum, nickel, nezvimwewo sebhainda. Izvo zviri mukati-yepamusoro-tembiricha carbides mune simende carbide inodarika iyo ye-high-speed simbi, ine yakanyanya kuoma (HRC75-94) uye yakanaka kupfeka kuramba.
Hard alloy red kuoma kunogona kusvika 800-1000 madhigirii. Iyo yekucheka kumhanya kwesimende carbide ndeye 4-7 nguva yakakwirira kupfuura iyo yesimbi inomhanya. Kunyatsocheka kwepamusoro.
Cemented carbide ine kuomarara kwakanyanya, simba, kupfeka-kusamira, uye corrosion resistance, uye inozivikanwa se "meno eindasitiri". Inoshandiswa kugadzira maturusi ekucheka, mapanga, maturusi ecobalt, uye zvikamu zvinopfekwa, uye inoshandiswa zvakanyanya mumauto, aerospace uye ndege, Mechanical processing, metallurgy, kuchera mafuta, maturusi emigodhi, kutaurirana kwemagetsi, kuvaka, uye mamwe minda. nekuvandudzwa kwemaindasitiri epasi, kudiwa kwemusika wecemented carbide kuri kuramba kuchiwedzera. Uye mune ramangwana, kugadzirwa kwezvombo zvemhando yepamusoro-soro nemidziyo, kufambira mberi kwesainzi uye tekinoroji, uye kukurumidza kukura kwesimba renyukireya kuchawedzera zvakanyanya kudiwa kwemhando yepamusoro-soro, uye yakagadzika simende zvigadzirwa zvecarbide. .
