Umahluko phakathi kweTungsten kunye neTungsten Carbide

Kwishishini lanamhlanje, iimveliso ze-tungsten carbide ziye zaba sisixhobo esidumileyo. Kwaye i-tungsten ayisetyenziselwa ibhalbhu kuphela. Kweli nqaku, siza kuthetha ngomahluko phakathi kwe-tungsten kunye ne-tungsten carbide. Eli nqaku liza kubonisa ngolu hlobo lulandelayo:

1. Yintoni i-tungsten?

2. Yintoni i-tungsten carbide?

3. Umahluko phakathi kwe-tungsten kunye ne-tungsten carbide.

Yintoni tungsten?

I-Tungsten yafunyanwa okokuqala ngo-1779, kwaye yaziwa ngokuba "ilitye elinzima" ngesiSwedish. I-Tungsten inezona ndawo ziphezulu zokunyibilika, elona nqanaba lisezantsi lokwandiswa kwe-coefficient, kunye noxinzelelo lomphunga oluphantsi phakathi kwesinyithi. I-Tungsten ikwane-elasticity entle kunye ne-conductivity.

Yintoni tungsten carbide?

I-tungsten carbide yi-alloy ye-tungsten kunye nekhabhoni. I-Tungsten carbide yaziwa njengeyesibini eyona nto inzima emhlabeni, emva kwedayimane. Ngaphandle kokuqina, i-tungsten carbide ikwanazo ukumelana nokunxiba kakuhle, ukuxhathisa ukubola, ukumelana nokothuka, kunye nokuqina.

Umahluko phakathi kwetungsten kunye netungsten carbide

Siza kuthetha ngomahluko phakathi kwe-tungsten kunye ne-tungsten carbide kule miba ilandelayo:

1. Imodyuli yeelastiki

I-Tungsten inemodyuli enkulu ye-elastic ye-400GPa. Nangona kunjalo, i-tungsten carbide inomnye omkhulu ojikeleze i-690GPa. Amaxesha amaninzi, ukuqina kwezixhobo kunxulumene nemodyuli elastiki. Imodyuli ephezulu yokuqina kwe-tungsten carbide ibonisa ukuqina okuphezulu kunye nokuchasana okuphezulu kwi-deformation.

2. Cheba imodyuli

Imodyuli yeShear ngumlinganiselo woxinzelelo lokucheba kuxinzelelo lokucheba, olukwabizwa ngokuba yimodyuli yobungqongqo. Ngokubanzi, iintsimbi ezininzi zinemodyuli yokucheba ejikeleze i-80GPa, i-tungsten ine-tungsten kabini, kunye ne-tungsten carbide kathathu.

3. Ukuqina kwesivuno esinamandla

Nangona i-tungsten kunye ne-tungsten carbide inobulukhuni obuhle kunye nokuqina, azinawo amandla aphezulu okuvelisa. Ngokubanzi, amandla emveliso ye-tungsten ajikeleze i-350MPa, kwaye i-tungsten carbide ijikeleze i-140MPa.

4. I-Thermal conductivity

I-Thermal conductivity iyimilinganiselo ebalulekileyo xa izinto zisetyenziswa kwindawo ephezulu yokushisa. I-Tungsten ine-conductivity ephezulu ye-thermal kune-tungsten carbide. I-Tungsten inozinzo lwendalo yobushushu, ngoko ke ilungele ukusetyenziswa kwe-thermal, njengemicu, iityhubhu, kunye neekhoyili zokufudumeza.

5. Ukuqina

I-Tungsten inobunzima be-66, ngelixa i-tungsten carbide inobunzima be-90. I-tungsten carbide iqukethe i-tungsten kunye nekhabhoni, ngoko ayinayo kuphela iimpawu ezintle ze-tungsten, kodwa iphinde ibe nobunzima kunye nokuzinza kweekhemikhali zekhabhoni.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
