carbide sima ua vaevaeina i tungsten-cobalt, tungsten-titanium, tungsten-titanium-tantalum-cobalt. Tungsten, cobalt, ma titanium o uʻamea malo malō.

1. Tungsten-cobalt carbide tipi meafaigaluega e aofia ai YG6, YG8, YG8N, ma isi mea. O nei ituaiga o carbide-cutting meafaigaluega e talafeagai mo le gaosiga o uʻamea e le o ferrous, uʻamea uʻamea, uʻamea lafo, ma isi mea;

2. Tungsten ma titanium carbide tipi meafaigaluega e aofia ai le YT5, YT15, ma isi. O lenei ituaiga o carbide-cutting meafaigaluega e talafeagai mo le gaosia o mea faigata e pei o le sila;

3. Tungsten-titanium-tantalum-cobalt carbide cutting tools e aofia ai: YW1, YW2, YS25, WS30, ma isi. O lenei ituaiga o carbide-cutting meafaigaluega e talafeagai mo le gaosia o mea faigata-i-masini e pei o le vevela vevela, manganese maualuga uamea, uamea uamea, ma isi.

Uiga fa'atinoga o carbide sima

1. Malosi maualuga (86 ~ 93HRA, tutusa ma 69 ~ 81HRC);

2. Malosi vevela lelei (e mafai ona oʻo i le 900 ~ 1000 ℃, tausia le 60HRC);

3. Lelei le ofuina o laei.

Mea faigaluega tipi Carbide o loʻo i ai le saoasaoa o le tipiina o le 4 i le 7 taimi e sili atu nai lo le uʻamea maualuga ma le ola meafaigaluega e 5 i le 80 taimi le umi. Mo le gaosiga o masini ma fuaina o meafaigaluega, o le ola tautua e 20 i le 150 taimi umi atu nai lo le uamea meafaigaluega. E mafai ona tipiina mea faigata ma le 50HRC. Ae ui i lea, o le carbide sima e matua maʻaleʻale ma e le mafai ona gaosia. E faigata ona fai se meafaigaluega tu'ufa'atasi foliga lavelave. O le mea lea, o lau o foliga eseese e masani ona faia ma faʻapipiʻi i luga o le tino meafaigaluega poʻo le tino faʻapipiʻi e faʻaaoga ai le uelo, faʻapipiʻi, faʻapipiʻi masini, ma isi.

Faavasegaina o carbide sima

1. Tungsten-cobalt carbide

O vaega autu o le tungsten carbide (WC) ma le binder cobalt (Co). O lona igoa fa'ailoga e aofia ai le "YG" (le pinyin Saina muamua o le "malosi, cobalt") ma le pasene o le averesi o le cobalt content. Mo se faʻataʻitaʻiga, YG8 o lona uiga o le averesi WCo = 8% ma le isi o le tungsten carbide tungsten cobalt carbide. E masani lava, tungsten-cobalt alloys e masani ona faʻaaogaina i meafaigaluega tipi carbide, faʻailoga, ma oloa faʻafanua ma minerale.

2. Tungsten titanium cobalt carbide

O vaega autu o tungsten carbide, titanium carbide (TiC), ma cobalt. O lona faʻailoga e aofia ai le "YT" (o le prefix o le pinyin Saina o le "malosi ma le titanium") ma le averesi o mea o le titanium carbide. Mo se faʻataʻitaʻiga, YT15 o lona uiga averesi TiC = 15%, ma le isi o le tungsten titanium cobalt sima carbide ma tungsten carbide ma cobalt anotusi.

3. Tungsten titanium tantalum (niobium) carbide

O vaega autu o le tungsten carbide, titanium carbide, tantalum carbide (poʻo le niobium carbide), ma le cobalt. O lenei ituaiga o carbide sima e taʻua foi o le universal sima carbide poʻo le universal cimented carbide. O lona igoa fa'ailoga e aofia ai le "YW" (le Chinese pinyin prefix o le "hard" ma le "wan") fa'atasi ai ma se numera fa'asologa, pei ole YW1.
