Usoro mmepụta nke cemented carbide agụba adịghị ka nkedo ma ọ bụ nchara, nke a na-etolite site na-agbaze ore wee na-agbanye n'ime ihe ndị a na-emepụta, ma ọ bụ na-emepụta site na-emepụta, ma carbide ntụ ntụ (tungsten carbide ntụ ntụ, titanium carbide ntụ ntụ, tantalum carbide ntụ ntụ) ga-abụ naanị. agbaze mgbe ọ ruru 3000 Celsius C ma ọ bụ karịa. ntụ ntụ, wdg) na-ekpo ọkụ karịa 1,000 degrees Celsius iji mee ka ọ gbanye. Iji mee ka njikọ carbide a sie ike, a na-eji ntụ ntụ cobalt mee ihe dị ka onye na-ejikọta ọnụ. N'okpuru omume nke okpomọkụ dị elu na nrụgide dị elu, mmekọrịta dị n'etiti carbide na cobalt ntụ ntụ ga-eme ka ọ dịkwuo mma, nke mere na ọ ga-eji nwayọọ nwayọọ na-etolite. A na-akpọ ihe omume a sintering. N'ihi na a na-eji ntụ ntụ eme ihe, usoro a ka a na-akpọ metallurgy powdery.

Dị ka usoro mmepụta ihe dị iche iche nke cemented Carbide Inserts si dị, ọnụ ọgụgụ dị ukwuu nke akụkụ nke ọ bụla nke ntinye carbide cemented dị iche, na arụmọrụ nke ntinye carbide simented arụpụtara dịkwa iche.

Manufacturing process of carbide inserts

Sintering na-eme mgbe akpụ. Ihe na-esonụ bụ usoro dum nke usoro ịme ihe:

1) Pịa tungsten carbide ntụ ntụ na ntụ ntụ cobalt dị ka achọrọ. N'oge a, a na-ejikọta ihe ndị ahụ ígwè na ibe ha, ma nchikota adịghị ike nke ukwuu, a ga-eji obere ike gwepịa ha.

2) Ka okpomọkụ nke ihe mgbochi ntụ ntụ kpụrụ na-abawanye, ogo njikọ na-eji nwayọọ nwayọọ na-ewusi ike. Na 700-800 Celsius C, nchikota nke irighiri ihe ka na-adighi ike, ma a ka nwere otutu oghere n'etiti ihe ndi ozo, nke a na-ahu ebe nile. A na-akpọ oghere ndị a voids.

3) Mgbe okpomọkụ okpomọkụ na-ebili na 900 ~ 1000 ° C, oghere dị n'etiti ihe ndị ahụ na-ebelata, akụkụ ojii nke linear fọrọ nke nta ka ọ ghara ịla n'iyi, na naanị nnukwu akụkụ ojii na-anọgide.

4) Mgbe okpomọkụ ji nwayọọ nwayọọ na-erute 1100 ~ 1300 ° C (ya bụ, nkịtị sintering okpomọkụ), ndị voids na-n'ihu belata, na bonding n'etiti ahụ na-esiwanye ike.

5) Mgbe emechara usoro ihe nkedo ahụ, ihe ndị dị na tungsten carbide dị na agụba bụ obere polygons, a pụkwara ịhụ ihe na-acha ọcha gburugburu ha, nke bụ cobalt. Nhazi agụba a gbadoro ụkwụ na-adabere na cobalt ma kpuchie ya na akụkụ carbide tungsten. Ogo na ọdịdị nke ihe ndị ahụ na ọkpụrụkpụ nke oyi akwa cobalt dịgasị iche iche na njirimara nke ntinye carbide.
