carbide simahe hua whakarewa paura i hangaia mai i te carbide (wc, tic) te paura micron-rahi o nga konganuku whakamaroke pakeke nui me te cobalt (co) ranei te nickel (ni) me te molybdenum (mo) hei here, he mea para ki roto i te oumu korehau, te oumu whakaheke hauwai ranei. .
I te wa hangahangacarbid simae, ko te rahi o te paura rauemi mata kua whiriwhiria kei waenga i te 1 me te 2 microns, a he tino tiketike te ma.Ko nga rauemi mata kua tohua kia rite ki te rahinga kua whakaritea, ka tapirihia ki te waipiro, ki etahi atu papaaho ranei i roto i te mira poro makuku, kia tino konatunatua, kuru, whakamaroke, tatari me te taapiri atu ki te ware pi, kapia ranei me etahi atu momo miihini whakakikorua, ka maroke. ka tatari kia hanga he ranunga.Na, ko te ranunga ka kohia, ka pehia, ka whakamahana kia tata ki te rewa o te whakarewa here (1300 ~ 1500 ℃), te wahanga whakapakeke me te whakarewa here ka hanga he koranu eutectic.
Whai muri i te whakamatao, ka tohatohahia nga wahanga whakapakeke ki roto i te matiti i titoa mai i nga konganuku herea, e hono tata ana ki a raua ano kia hangai he katoa.Ko te pakeke o te carbide cimented e whakawhirinaki ana ki te kiko o te wahanga whakapakeke me te rahi o te witi, ara, ki te teitei ake o te waahanga whakapakeke me te pai ake o te witi, ka nui ake te pakeke.Te pakari ocarbide simaka whakatauhia e te whakarewa hononga, me te teitei ake o te ihirangi whakarewa, ka nui ake te kaha o te piko.
