Umehluko phakathi kweTungsten neTungsten Carbide

Embonini yesimanje, imikhiqizo ye-tungsten carbide isiphenduke ithuluzi elidumile. Futhi i-tungsten ayisetshenziselwa isibani kuphela. Kulesi sihloko, sizokhuluma ngomehluko phakathi kwe-tungsten ne-tungsten carbide. Lesi sihloko sizobonisa kanje:

1. Iyini i-tungsten?

2. Iyini i-tungsten carbide?

3. Umehluko phakathi kwe-tungsten ne-tungsten carbide.

Yini i-tungsten?

I-Tungsten yaqala ukutholakala ngo-1779, futhi yaziwa ngokuthi "itshe elisindayo" ngesiSwidi. I-Tungsten inamaphuzu aphezulu kakhulu okuncibilika, i-coefficient enwetshiwe ephansi kakhulu, kanye nomfutho womhwamuko ophansi kakhulu phakathi kwezinsimbi. I-Tungsten nayo inokunwebeka okuhle nokuhamba kahle.

Iyini i-tungsten carbide?

I-Tungsten carbide iyingxube ye-tungsten ne-carbon. I-Tungsten carbide yaziwa njengento yesibili enzima kakhulu emhlabeni, ngemuva kwedayimane. Ngaphandle kokuqina, i-tungsten carbide nayo inokumelana okuhle nokugqokwa, ukumelana nokugqwala, ukumelana nokushaqeka, nokuqina.

Umehluko phakathi kwe-tungsten ne-tungsten carbide

Sizokhuluma ngomehluko phakathi kwe-tungsten ne-tungsten carbide kulezi zici ezilandelayo:

1. Imoduli ye-elastic

I-Tungsten ine-modulus enkulu yokunwebeka ye-400GPa. Kodwa-ke, i-tungsten carbide inenkulu kunama-690GPa. Isikhathi esiningi, ukuqina kwempahla kuhlobene ne-elastic modulus. I-modulus ephakeme yokunwebeka kwe-tungsten carbide ikhombisa ukuqina okuphezulu kanye nokumelana okuphezulu nokuguqulwa.

2. Shear modulus

I-Shear modulus isilinganiso sengcindezi ye-shear kuya ku-shear strain, ebizwa nangokuthi i-modulus of rigidity. Ngokuvamile, izinsimbi eziningi zine-shear modulus ezungeze i-80GPa, i-tungsten ine-tungsten kabili, ne-tungsten carbide kathathu.

3. Amandla esivuno esiqinile

Nakuba i-tungsten ne-tungsten carbide inobulukhuni obuhle nokuqina, azinawo amandla aphezulu okukhiqiza. Ngokuvamile, amandla okukhiqiza e-tungsten aqinile angaba ngu-350MPa, kanti awe-tungsten carbide acishe abe ngu-140MPa.

4. I-thermal conductivity

I-Thermal conductivity iyisilinganiso esibalulekile lapho impahla isetshenziswa endaweni yokushisa ephezulu. I-Tungsten ine-thermal conductivity ephakeme kune-tungsten carbide. I-Tungsten inokuzinza kwemvelo kwezinga lokushisa, ngakho-ke ilungele ukusetshenziswa kwezinye izinto ezishisayo, njengemicu, amashubhu, namakhoyili okushisa.

5. Ubulukhuni

I-Tungsten inobunzima obungu-66, kuyilapho i-tungsten carbide inobunzima obungama-90. I-tungsten carbide iqukethe i-tungsten ne-carbon, ngakho ayinayo kuphela izici ezinhle ze-tungsten, kodwa futhi inobulukhuni nokuzinza kwamakhemikhali ekhabhoni.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
