Whakaahuatanga Hua

Ko te Tantalum carbide (TaC) he mea tino uaua (Mohs hardess 9-10) he rawa uku whakaahuru. He taimana anake te pakeke. He paura taumaha, parauri i te nuinga o te wa ka tukatukahia ma te whakahiato, me tetahi taonga cermet nui. I etahi wa ka whakamahia hei taapiri kirikiri-pai ki nga tungsten carbide alloys. Ko te Tantalum carbide te mea motuhake ko te puhui-rua stoichiometric me te ira whakarewa teitei e mohiotia ana, i te 4150 K (3880°C). Ko te pūhui substoichiometric TaC0.89 he teitei ake te ira whakarewa, tata ki te 4270 K (4000°C)

Taupānga

1) Ko te tantalum carbide he maha nga wa ka taapirihia ki te tungsten carbide / kobalt (WC / Co) paura paura ki te whakarei ake i nga ahuatanga o te tinana o te hanganga sintered. Ka mahi ano ia hei aukati i te tipu o te witi hei aukati i te hanga o nga karepe nui, na reira ka puta mai he rauemi tino uaua.

2) Ka whakamahia ano hoki hei whakakikorua mo nga raima rino i roto i te werohanga o te konumohe konumohe. Ahakoa e whakarato ana i te mata pakeke, mau i te atete, ka whakarato hoki i te mata pokepokea waku iti.

3) Ka whakamahia ano te Tantalum carbide i roto i te hanga o nga taputapu koi me te kaha o te aukati miihini me te pakeke.

4) Ka whakamahia ano i roto i nga moka taputapu mo te tapahi taputapu.
