Cemented carbide ke phofo ea metallurgy sehlahisoa se entsoeng ka carbide (WC, TiC) micron-level powder ea high hardness refractory metale e le karolo ea mantlha, e nang le cobalt (Co) kapa nickel (Ni), molybdenum (Mo) e le binder, e thahasellang sebopi sa vacuum kapa sebopi sa ho fokotsa haedrojene.
Classification le Kereiti
①Tungsten le Cobalt Cemented Carbide
Karolo e ka sehloohong ke tungsten carbide (WC) le binder cobalt (Co).
Sehlopha se entsoe ka "YG" ("hard, cobalt" ka Hanyu Pinyin) le peresente ea kakaretso ea cobalt.
Mohlala, YG8, e bolela kakaretso ea WCo = 8%, 'me e setseng ke tungsten carbide carbide.
②Tungsten, titanium le cobalt e entsoeng ka samente carbide
Likarolo tse ka sehloohong ke tungsten carbide, titanium carbide (TiC) le cobalt.
Sehlopha se entsoe ka "YT" ("hard, titanium" ka Hanyu Pinyin) le kakaretso ea litaba tsa titanium carbide.
Mohlala, YT15, e bolela kakaretso ea WTi = 15%, e setseng ke tungsten carbide le cobalt content ea tungsten titanium cobalt carbide.
③Tungsten-titanium-tantalum (niobium) mofuta oa carbide
Likarolo tse ka sehloohong ke tungsten carbide, titanium carbide, tantalum carbide (kapa niobium carbide) le cobalt.Mofuta ona oa carbide o boetse o bitsoa carbide-purpose-purpose kapa universal carbide.
