Otu esi ezere mgbawa na ngwaahịa mpụ nke carbide cimented

A na-ejikarị teknụzụ extrusion ntụ ntụ mepụta ngwaahịa tungsten carbide na mkpanaka carbide na mmepụta nke ngwaahịa carbide tungsten. Ọkpụkpụ carbide siri ike bụ teknụzụ nwere ike imepụta na mmepụta carbide cimented ọgbara ọhụrụ. Otú ọ dị, ngwaahịa extrusion ka nwere ike ịpụta mgbawa n'oge usoro mmepụta. Isiokwu a ga-ekwu maka otu esi ezere mgbawa na ịkpụzi carbide extrusion cimented.

Ụzọ extrusion nwere ihe pụrụ iche ma e jiri ya tụnyere nkà na ụzụ ịkpụzi omenala na nkà na ụzụ ịpị nke isotactic. Usoro mmepụta nke cemented carbide extrusion molding gụnyere usoro ndị a: ngwakọta nke ntụ ntụ na onye na-emepụta ihe → extrusion molding → nkwadebe ọkụ → vacuum sintering → okokụre ngwaahịa nkwakọ ngwaahịa → okokụre ngwaahịa. Usoro mmepụta yiri ka ọ dị mfe n'ezie, ma ọ dị nnọọ mfe ịmepụta ngwaahịa mkpofu gbawara agbawa ma ọ bụrụ na enwere nleghara anya n'oge mmepụta.

Enwere ọtụtụ ihe kpatara mgbawa, dị ka ntọala nhazi na-enweghị ezi uche nke extrusion anwụ, onye na-emepụta ihe na-adịghị mma, arụ ọrụ ịkpụzi adịghị mma nke ngwakọta, usoro mkpochapụ na-ekwesịghị ekwesị, usoro ntinye nke mbụ, na sintering usoro, wdg.
