Nhazi nke carbide cimented

1. Tungsten-cobalt carbide

Ihe ndị bụ isi bụ tungsten carbide (WC) na binder cobalt (Co). Aha ika ya bụ "YG" (pinyin China izizi nke "hard, cobalt") na pasent nke ọdịnaya cobalt dị nkenke. Dịka ọmụmaatụ, YG8 pụtara na nkezi WCo = 8% na ndị ọzọ bụ tungsten carbide tungsten cobalt carbide. N'ozuzu, a na-ejikarị tungsten-cobalt alloys eme ihe na ngwá ọrụ ndị na-egbutu carbide, ebu, na ngwaahịa ala na ịnweta.

2. Tungsten titanium cobalt carbide

Ihe ndị bụ isi bụ tungsten carbide, titanium carbide (TiC), na cobalt. Akara ya nwere "YT" (nhụgharị nke pinyin Chinese nke "hard na titanium") na nkezi ọdịnaya nke titanium carbide. Dịka ọmụmaatụ, YT15 pụtara nkezi TiC = 15%, nke ọzọ bụ tungsten titanium cobalt cemented carbide nwere tungsten carbide na ọdịnaya cobalt.

3. Tungsten titanium tantalum (niobium) carbide

Ihe ndị bụ isi bụ tungsten carbide, titanium carbide, tantalum carbide (ma ọ bụ niobium carbide), na cobalt. A na-akpọkwa ụdị carbide cemented a na-akpọ carbide cemented eluigwe na ala ma ọ bụ carbide cemented eluigwe na ala. Aha ika ya nwere "YW" (nha mbido pinyin nke China nke "hard" na "wan") gbakwunyere nọmba serial, dị ka YW1.
