Yintoni umahluko phakathi kwe-YT-type cemented carbide kunye ne-YG-type cemented carbide?

1. Izithako ezahlukeneyo

Izinto eziphambili ze-carbide eqinisiweyo yohlobo lwe-YT yi-tungsten carbide, i-titanium carbide (TiC) kunye ne-cobalt. Uhlobo lwayo lwenziwe ngoonobumba ababini abathi “YT” (“hard, titanium” kwi-Chinese Pinyin prefix) kunye nomxholo ophakathi we-titanium carbide. Umzekelo, i-YT15 ithetha ukuba umyinge we-TiC=15%, kwaye okuseleyo yi-tungsten-titanium-cobalt carbide enomxholo we-tungsten carbide kunye nomxholo we-cobalt.

Izinto eziphambili ze-YG cemented carbide yi-tungsten carbide (WC) kunye ne-cobalt (Co) njenge-binder. Uhlobo lwayo lwenziwe yi-“YG” (“hard and cobalt” kwi-Chinese Pinyin) kunye nepesenti yomxholo ophakathi we-cobalt. Umzekelo, i-YG8 ithetha i-WCo=8%, kwaye enye yi-tungsten-cobalt carbide ye-tungsten carbide.
2. Ukusebenza okwahlukileyo

I-carbide eqinisiweyo yohlobo lwe-YT inokumelana nokuguguleka okuhle, amandla okugoba aphantsi, ukusebenza kokugaywa, kunye nokuqhuba kobushushu, ngelixa i-carbide eqinisiweyo yohlobo lwe-YG inokuqina okuhle, ukusebenza kakuhle kokugaywa, kunye nokuqhuba kobushushu okuhle, kodwa ukumelana kwayo nokuguguleka kuphezulu kune-carbide eqinisiweyo yohlobo lwe-YT.

3. Iindlela ezahlukeneyo zokusetyenziswa

I-carbide efakwe isamente yohlobo lwe-YT ifanelekile ekusikweni kwentsimbi ngokubanzi ngesantya esiphezulu ngenxa yokuba ibuthathaka kakhulu kubushushu bayo obuphantsi, ngelixa i-carbide efakwe isamente yohlobo lwe-YG isetyenziselwa ukucubungula izinto ezibuthathaka (ezifana nesinyithi esityhidiweyo), iintsimbi ezingezizo iintsimbi kunye neentsimbi ze-alloy.
