I-carbide ene-cemented ihlulwe ibe yi-tungsten-cobalt, i-tungsten-titanium, i-tungsten-titanium-tantalum-cobalt. I-Tungsten, i-cobalt, kunye ne-titanium zi-brittle hard alloys.

1. Izixhobo zokusika i-tungsten-cobalt carbide ziquka i-YG6, i-YG8, i-YG8N, njl. Ezi ntlobo zezixhobo zokusika i-carbide zifanelekile ukucutshungulwa kweentsimbi ezingenayo i-ferrous, i-stainless steel, i-cast iron, kunye nezinye izinto;

2. Izixhobo zokusika i-tungsten kunye ne-titanium carbide ziquka i-YT5, i-YT15, njl. Olu hlobo lwesixhobo sokusika i-carbide lufanelekile ukucubungula izinto ezinzima ezifana nentsimbi;

3. I-tungsten-titanium-tantalum-cobalt izixhobo zokusika i-carbide ziquka: i-YW1, i-YW2, i-YS25, i-WS30, njl. Olu hlobo lwesixhobo sokusika i-carbide lufanelekile ukucubungula izinto ezinzima kumatshini ezifana nentsimbi ekwazi ukumelana nobushushu, i-manganese ephezulu. intsimbi, intsimbi engatyiwa, njl.

Iimpawu zokusebenza ze-carbide enesamente

1. Ubunzima obuphezulu (86 ~ 93HRA, elilingana ne-69 ~ 81HRC);

2. Ubunzima obuhle be-thermal (bunokufikelela kwi-900 ~ 1000 ℃, gcina i-60HRC);

3. Ukumelana nokunxiba kakuhle.

Izixhobo zokusika i-Carbide zinesantya sokusika i-4 ukuya kumaxesha angama-7 aphezulu ngaphezu kwensimbi ephezulu kunye nobomi besixhobo esi-5 ukuya kumaxesha angama-80 ubude. Ukwenziwa kwesikhunta kunye nezixhobo zokulinganisa, ubomi benkonzo bubude be-20 ukuya ku-150 ixesha elide kunolo lwensimbi yensimbi ye-alloy. Inokusika izinto eziqinileyo malunga ne-50HRC. Nangona kunjalo, i-carbide enesamente i-brittle kakhulu kwaye ayikwazi ukuqhutyelwa phambili. Kunzima ukwenza isixhobo esidityanisiweyo esinemilo entsonkothileyo. Ke ngoko, iiblade zeemilo ezahlukeneyo zihlala zenziwe kwaye zifakwe kumzimba wesixhobo okanye umzimba wokubumba usebenzisa i-welding, i-bonding, i-clamping yomatshini, njl.

Ukuhlelwa kwekhabhide enesamente

1. I-Tungsten-cobalt carbide

Amacandelo aphambili yi-tungsten carbide (WC) kunye ne-binder cobalt (Co). Igama layo lebrand liqulunqwe ngu "YG" (i-pinyin yokuqala yaseTshayina ye "hard, cobalt") kunye nepesenti yomxholo we-cobalt ophakathi. Umzekelo, i-YG8 ithetha ukuba i-avareji ye-WCo=8% kwaye enye yi-tungsten carbide tungsten cobalt carbide. Ngokubanzi, ii-alloys ze-tungsten-cobalt zisetyenziswa ikakhulu kwizixhobo zokusika i-carbide, ukubumba, kunye neemveliso zejoloji kunye nezimbiwa.

2. I-tungsten titanium cobalt carbide

Amacandelo aphambili yi-tungsten carbide, titanium carbide (TiC), kunye ne-cobalt. Uphawu lwayo luqukethe "YT" (isiqalo se-pinyin yaseTshayina "enzima kunye ne-titanium") kunye nomxholo ophakathi we-titanium carbide. Umzekelo, i-YT15 ithetha i-avareji ye-TiC=15%, kwaye enye yi-tungsten titanium cobalt cemented carbide ene-tungsten carbide kunye nomxholo we-cobalt.

3. I-tungsten titanium tantalum (niobium) carbide

Amacandelo aphambili yi-tungsten carbide, i-titanium carbide, i-tantalum carbide (okanye i-niobium carbide), kunye ne-cobalt. Olu hlobo lwe-cemented carbide lukwabizwa ngokuba yi-universal cemented carbide okanye i-universal cemented carbide. Igama layo lebrand liqulathe "YW" (i-Chinese pinyin prefix ethi "hard" kunye no "wan") kunye nenombolo yesiriyali, efana noYW1.
