Kalmomi Game da Tungsten Carbide

Tare da haɓaka fasahar fasaha, mutane suna bin ingantattun kayan aiki, da kayan aikin gini da kasuwancin su. A karkashin wannan yanayi, tungsten carbide yana taka muhimmiyar rawa a masana'antar zamani. Kuma a cikin wannan labarin, za a gabatar da wasu kalmomi game da tungsten carbide.

1. Siminti na siminti

Carbide da aka yi da siminti yana nufin haɗaɗɗen haɗaɗɗen haɗaɗɗun carbides na ƙarfe masu jujjuyawar da kuma masu ɗaure ƙarfe. Daga cikin abubuwan da ake amfani da su na karfe, tungsten carbide, titanium carbide, tantalum carbide, da sauransu sune carbides da aka saba amfani dasu a halin yanzu. Kuma abin daurin karfe da aka fi amfani da shi shine foda na cobalt, da sauran abubuwan daurin karfe kamar nickel, da iron, suma za a yi amfani da su a wasu lokuta.

2. Tungsten carbide

Tungsten carbide wani nau'i ne na siminti mai siminti, wanda ya ƙunshi foda na tungsten carbide da masu ɗaure ƙarfe. Tare da babban wurin narkewa, samfuran carbide tungsten ba za a iya kera su azaman sauran kayan ba. Karfe foda hanya ce ta gama gari don kera samfuran carbide tungsten. Tare da atom tungsten da carbon carbon, samfuran tungsten carbide suna da kyawawan kaddarorin da yawa, suna mai da su mashahurin kayan aiki a masana'antar zamani.

3. Yawan yawa

Maɗaukaki yana nufin rabon taro zuwa ƙarar kayan. Har ila yau, ƙarar sa yana ƙunshe da ƙarar pores a cikin kayan.

A cikin samfuran carbide tungsten, cobalt ko wasu barbashi na ƙarfe sun wanzu. YG8 na yau da kullun na tungsten carbide, wanda ke cikin 8% cobalt, yana da yawa na 14.8g/cm3. Sabili da haka, yayin da abun ciki na cobalt a cikin tungsten-cobalt gami ya karu, gabaɗayan yawa zai ragu.

4. Tauri

Taurin yana nufin iyawar abu don tsayayya da nakasar filastik. Ana amfani da taurin Vickers da taurin Rockwell don auna taurin samfuran carbide tungsten.

Vickers hardness ana amfani da ko'ina a duniya. Wannan hanyar auna taurin tana nufin ƙimar taurin da aka samu ta hanyar auna girman shigar ta hanyar amfani da lu'u-lu'u don shiga saman samfurin ƙarƙashin wani yanayi na kaya.

Rockwell hardness wata hanya ce ta auna taurin da ake amfani da ita. Yana auna taurin ta amfani da zurfin shigar mazugi na lu'u-lu'u.

Dukansu hanyar auna taurin Vickers da hanyar auna taurin Rockwell ana iya amfani da su don auna taurin simintin carbide, kuma ana iya jujjuya su biyu tare.

Tauri na tungsten carbide jeri daga 85 HRA zuwa 90 HRA. Matsayi na gama gari na tungsten carbide, YG8, yana da taurin 89.5 HRA. Samfurin carbide tungsten tare da babban taurin zai iya jure tasiri kuma ya sa mafi kyau, don haka yana iya yin aiki tsawon lokaci. A matsayin haɗin gwiwa, ƙarancin cobalt yana haifar da mafi kyawu. Kuma ƙananan carbon iya sa tungsten carbide wuya. Amma decarbonization na iya sa tungsten carbide sauƙi lalacewa. Gabaɗaya, ingantaccen carbide tungsten zai ƙara taurin sa.

5. Karfin lankwasa

Ana ninka samfurin azaman katako mai goyan baya kawai akan fulcrums biyu, kuma ana amfani da kaya a tsakiyar layin fulcrums biyu har sai samfurin ya karye. Ana amfani da ƙimar da aka ƙididdige ta hanyar dabarar iska bisa ga nauyin da ake buƙata don raguwa da yanki na yanki na samfurin. Hakanan aka sani da ƙarfin karyewar juriya ko juriya.

A cikin WC-Co tungsten carbide, ƙarfin sassauƙa yana ƙaruwa tare da haɓaka abun ciki na cobalt na tungsten-cobalt gami, amma lokacin da abun ciki na cobalt ya kai kusan 15%, ƙarfin flexural ya kai matsakaicin ƙimar, sannan ya fara saukowa.

Ƙarfin lanƙwasawa ana auna shi ta matsakaicin ma'auni da yawa da aka auna. Wannan ƙimar kuma za ta canza azaman lissafi na samfurin, yanayin saman, damuwa na ciki, da lahani na ciki na canjin kayan. Sabili da haka, ƙarfin juzu'i shine ma'auni na ƙarfin kawai, kuma ba za a iya amfani da ƙimar ƙarfin ƙarfi baa matsayin tushen zaɓin kayan abu.

6. Ƙarfin fashewar juyawa

Ƙarfin fashewar juzu'i shine ikon tungsten carbide don tsayayya da lankwasawa. Tungsten carbide tare da ingantacciyar ƙarfin fashewar juzu'i ya fi wahalar lalacewa ƙarƙashin tasiri. Kyakkyawan carbide tungsten yana da mafi kyawun karyewar ƙarfi. Kuma a lokacin da barbashi na tungsten carbide rarraba a ko'ina, transverse ne mafi alhẽri, kuma tungsten carbide ba sauki a lalace. Ƙarfin fashewar juzu'i na samfuran YG8 tungsten carbide yana kusa da 2200 MPa.

7. Karfin tilastawa

Ƙarfin tilastawa shine ragowar ƙarfin maganadisu da aka auna ta hanyar yin maganadisu a cikin siminti mai siminti zuwa cikakkiyar yanayi sannan kuma ya lalata shi.

Akwai dangantaka kai tsaye tsakanin matsakaicin girman barbashi na simintin carbide lokaci da ƙarfin tilastawa. Mafi kyawun matsakaicin girman barbashi na lokacin magnetized, mafi girman ƙimar ƙarfin tilastawa. A cikin dakin gwaje-gwaje, ana gwada karfin tilastawa ta mai gwada karfi.

Waɗannan su ne kalmomin tungsten carbide da kaddarorin sa. Za a kuma gabatar da ƙarin wasu kalmomi a cikin labarai masu zuwa.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
