Yadda ake Samar da Tungsten Carbide

Dukanmu mun san cewa ana yin alluran carbide daga tungsten carbide, amma kun san sirrin yadda ake samar da shi? Wannan nassi zai iya ba ku amsa. Samar da siminti na siminti shine a haɗa foda na carbide da foda mai haɗin gwiwa a cikin wani ƙayyadaddun ƙayyadaddun, matsawa cikin siffofi daban-daban, sa'an nan kuma ya zama Semi-sintered. Matsakaicin zafin jiki shine 1300-1500 ° C.

Lokacin kera siminti carbide, foda da aka zaɓa yana da girman barbashi tsakanin 1 da microns 2, kuma tsarkin yana da girma sosai. Ana haɗe foda na albarkatun ƙasa bisa ga ƙayyadaddun rabo na abun da ke ciki, yana iya kaiwa maki daban-daban bisa ga nau'ikan WC daban-daban da foda. Daga nan sai a zuba matsakaicin a cikin injin da ake jika don niƙa su don yin su gabaɗaya a niƙa. Bayan bushewa da sieve, ana ƙara abin da aka samar da shi, kuma ana shanya cakuda kuma a daskare. Bayan haka, lokacin da cakuda ya zama granulated da dannawa, kuma ya yi zafi kusa da wurin narkewa na karfe (1300-1500 ° C), lokacin taurara da ƙarfe mai ɗaure zai samar da eutectic gami. Bayan sanyaya, an kafa cikakken cikakke. Tauri na siminti carbide ya dogara da abun ciki na WC da girman hatsi, wato, yawan adadin WC da mafi kyawun hatsi, mafi girman taurin. An ƙayyade taurin kayan aikin carbide ta hanyar haɗin gwiwa. Mafi girman abun ciki na ƙarfe na haɗin gwiwa, mafi girma ƙarfin lanƙwasawa.

Kuna tsammanin bayan sanyaya samfurin ya cika?

Amsar ita ce a'a! Bayan haka, za a aika don gwaje-gwaje masu yawa. Samfuran carbide na Tungsten na iya nuna bambanci a cikin kayan aikin injiniya a cikin abubuwan sinadaran, tsarin nama, da tsarin kula da zafi. Sabili da haka, ana amfani da gwajin tauri sosai a cikin bincikar kaddarorin carbide, wanda zai iya kula da daidaitaccen tsarin maganin zafi da bincike na sabbin kayan. Gano taurin tungsten carbide galibi yana amfani da na'urar gwajin taurin Rockwell don gwada ƙimar taurin HRA. Gwajin yana da siffa mai ƙarfi da daidaita girman girman yanki na gwaji tare da babban inganci.

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.
