Isọri ti simenti carbide
1. Tungsten-koluboti carbide
Awọn paati akọkọ jẹ tungsten carbide (WC) ati cobalt binder (Co). Orukọ ami iyasọtọ rẹ ni “YG” (pinyin Kannada akọkọ ti “lile, cobalt”) ati ipin ogorun akoonu koluboti apapọ. Fun apẹẹrẹ, YG8 tumọ si pe apapọ WCo = 8% ati iyokù jẹ tungsten carbide tungsten kobalt carbide. Ni gbogbogbo, awọn ohun elo tungsten-cobalt ni a lo ni akọkọ ninu awọn irinṣẹ gige-carbide, awọn apẹrẹ, ati awọn ọja ti ẹkọ-aye ati nkan ti o wa ni erupe ile.
2. Tungsten titanium koluboti carbide
Awọn paati akọkọ jẹ tungsten carbide, titanium carbide (TiC), ati koluboti. Aami rẹ ni “YT” (iṣaaju ti pinyin Kannada ti “lile ati titanium”) ati akoonu apapọ ti carbide titanium. Fun apẹẹrẹ, YT15 tumọ si apapọ TiC = 15%, ati pe iyokù jẹ tungsten titanium cobalt cemented carbide pẹlu tungsten carbide ati akoonu koluboti.
3. Tungsten titanium tantalum (niobium) carbide
Awọn paati akọkọ jẹ tungsten carbide, titanium carbide, tantalum carbide (tabi niobium carbide), ati koluboti. Iru iru carbide cemented ni a tun pe ni carbide cemented agbaye tabi carbide cemented agbaye. Orukọ ami iyasọtọ rẹ ni “YW” (ipejumọ pinyin Kannada ti “lile” ati “wan”) pẹlu nọmba ni tẹlentẹle, bii YW1.
