Ọdịiche dị n'etiti PCD na PDC

PDC na PCD bụ ihe ọhụrụ siri ike. Kedu ihe dị iche n'etiti ha?

PCD (Polycrystalline Diamond) bụ nke ejiri diamond grit mee ya. Ejikọtala grit diamond n'okpuru nrụgide dị elu, ọnọdụ okpomọkụ dị elu na ọnụnọ nke ígwè catalytic. PCD nwere ike siri ike, na-eyi nkwụsi ike, yana nrụpụta ọkụ na diamond, nke na-eme PCD bụrụ ihe dị mma maka ịkpụ ngwaọrụ. Ngwa PCD (dị ka ntinye PCD na agụba PCD) nwere ike igwe ihe niile na-abụghị igwe dị ka nke a na-eji na ụlọ ọrụ osisi, chipboards, HDF, na bọọdụ laminated. A na-eji PCD na ụlọ ọrụ ụgbọ ala na-emepụta ihe ndị aluminom na ihe niile dị fechaa dị ka carbon fiber mebere plastics (CFRP), metal matrix composites (MMC), na nchịkọta maka ịrụ ụgbọ elu.

PDC (Polycrystalline Diamond Compact) na-ezo aka na polycrystalline diamond composite ma ọ bụ kọmpat, nke bụ ngwa ọrụ kachasị sie ike n'etiti ihe ngwaọrụ diamond niile. A na-eme ya site na ijikọta ụfọdụ n'ígwé nke polycrystalline diamonds (PCD) na oyi akwa nke cemented carbide substrate na elu okpomọkụ na elu nrụgide. Ọnọdụ okpomọkụ dị gburugburu 1400 ~ 1700 ℃, na nrụgide dị gburugburu 6-7 GPA. Otu cobalt alloy dịkwa ugbu a ma na-arụ ọrụ dị ka ihe na-akpali akpali maka usoro ịme ihe. Cobalt na-enyere aka jikọta carbide na diamond. PDC nwere uru nke nguzogide akwa diamond na ịdị mma nke carbide.

Ndụ ọrụ nke ndị na-egbutu PDC na-abawanye karịa 6 ~ 10 ugboro

Belata ugboro nke nnọchi nke mkpọpu ihe na ike ọrụ nke ndị ọrụ.

N'ihi arụmọrụ ha dị elu, a na-eji ndị na-egbutu PDC eme ihe n'akụkụ ndị a:

Mmanụ na gas PDC ibe n'ibe dị ka ihu, nlele, na ndabere cutters

Mpekere PDC maka mkpọpu ala geothermal

PDC ibe n'ibe maka igwu olulu mmiri

PDC ibe n'ibe maka ntụziaka mkpọpu

N'ebe a na zzbetter, Anyị na-enye ụdị dị iche iche na nha nha nke ndị na-egbutu PDC.

Ọdịdị nke zzbetter PDC Cutter

1. Flat PDC cutter

2. Spherical PDC bọtịnụ

3. Parabolic PDC bọtịnụ, n'ihu bọtịnụ

4. Conical PDC bọtịnụ

5. Square PDC cutters

6. Ndị na-egbutu PDC na-adịghị mma

Ọ bụrụ na ị nwere mmasị na ndị cutters PDC ma chọọ ozi ndị ọzọ na nkọwapụta, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe ahụ.
