Mmetụta nke ọgwụgwọ mkpuchi elu diamond

1. Echiche nke mkpuchi elu diamond

Ihe mkpuchi elu diamond, na-ezo aka iji teknụzụ ọgwụgwọ elu n'elu diamond nke ejiri ihe nkiri ihe ndị ọzọ kpuchie ya. Dị ka ihe mkpuchi, na-abụkarị ígwè (gụnyere alloy), dị ka ọla kọpa, nickel, titanium, molybdenum, ọla kọpa tin titanium alloy, nickel cobalt alloy, nickel cobalt phosphorus alloy, wdg; mkpuchi ihe nwekwara ụfọdụ na-abụghị ọla ihe, dị ka ceramik, titanium carbide, titanium amonia na ndị ọzọ ogige refractory ike ihe. Mgbe ihe mkpuchi bụ ígwè, a pụkwara ịkpọ ya metalation surface metal.

Ebumnuche nke mkpuchi elu bụ inye ụmụ irighiri diamond nwere ihe pụrụ iche nke anụ ahụ na kemịkalụ, iji meziwanye mmetụta ha. Dị ka ihe atụ, ojiji nke elu-ntekwasa diamond abrasive n'ichepụta resin egweri wheel, ya ọrụ ndụ na-ukwuu gbatịa.

2. Nhazi nke usoro mkpuchi elu

Industrial n'elu ọgwụgwọ usoro nhazi ọkwa na-ahụ na ọnụ ọgụgụ dị n'okpuru ebe a, nke e tinye n'ezie na ibu siri ike abrasive elu mkpuchi usoro, ọzọ ewu ewu bụ tumadi mmiri chemical plating (enweghị electrolysis plating) na plating, akọrọ plating (nke a makwaara dị ka agụụ plating) na chemical vapor deposition (CVD) na anụ ahụ vepor deposition (PVD), gụnyere agụụ ntụ ntụ metallurgy ngwa, mmiri mmiri mmehie usoro bara uru.

 

3. Plating ọkpụrụkpụ na-anọchi anya usoro

N'ihi na ọkpụrụkpụ mkpuchi nke elu nke ihe abrasive diamond siri ike ikpebi kpọmkwem, a na-egosipụtakarị ya dị ka ibu ibu (%). Enwere ụzọ abụọ iji gosipụta oke ibu:

Ebe A bụ oke ibu (%); G1 bụ ibu egweri tupu etinye ya; G2 bụ ibu mkpuchi; G bụ mkpokọta arọ (G=G1 + G2)

4. Mmetụta nke mkpuchi elu diamond na arụmọrụ ngwá ọrụ diamond

N'ime ngwa diamond ejiri Fe, Cu, Co na Ni mee, enwere ike itinye irighiri diamond na igwe na-ejikọta ya na matriks nke na-ejikọta ya n'ihi enweghị njikọ kemịkalụ nke onye na-ejikọta ihe dị n'elu yana enweghị ntinye interface. N'okpuru omume nke ichikota ike, mgbe diamond na-egweri urughuru na-ekpughere na kacha nke ngalaba, taya taya ga-efunahụ ahụ diamond ahụ na-ada pụọ n'onwe ya, nke na-ebelata ọrụ ndụ na nhazi arụmọrụ nke diamond ngwaọrụ, na egweri mmetụta nke diamond enweghị ike zuru ezu egwuri. Ya mere, elu diamond nwere njirimara metallization, nke nwere ike imeziwanye ndụ ọrụ na nhazi nhazi nke ngwaọrụ diamond. Ihe kachasị ya mkpa bụ ime ka ihe ndị ahụ jikọtara ọnụ dị ka Ti ma ọ bụ alloy ya kpuchie ya ozugbo n'elu diamond, site na ikpo ọkụ na ọgwụgwọ kpo oku, nke mere na elu diamond na-etolite akwa mkpuchi kemịkalụ edo.
Site n'ikpuchi ihe ndị na-egweri diamond, mmeghachi omume nke mkpuchi na diamond iji mee ka elu diamond dị mma. N'aka nke ọzọ, na metallized diamond n'elu na metal ahụ adịgide adịgide gị n'etiti metal metallurgical Nchikota, Ya mere, mkpuchi ọgwụgwọ nke diamond n'ihi na oyi na-atụ mmiri mmiri sintering na-ekpo ọkụ siri ike na-adọ sintering nwere wide applicability, otú taya ahụ alloy maka diamond egweri ọka consolidation mụbara, belata diamond ngwá ọrụ na ojiji nke egweri, iji melite ọrụ ndụ na arụmọrụ nke diamond ngwaọrụ.

5. Kedu ọrụ bụ isi nke ọgwụgwọ mkpuchi diamond?

1. Melite ikike inlay nke ahụ nwa ebu n'afọ iji tinye diamond.
N'ihi mgbasawanye okpomọkụ na mkpirisi oyi, a na-ebute nnukwu nrụgide okpomọkụ na mpaghara kọntaktị dị n'etiti diamond na ahụ taya, nke ga-eme ka diamond na eriri ahụ nwa ebu n'afọ mepụta obere ahịrị, si otú a na-ebelata ikike nke taya taya na diamond. Of diamond n'elu mkpuchi nwere ike imeziwanye anụ ahụ na chemical Njirimara nke diamond na ahu interface, site ume ụdịdị dị iche iche analysis, kwadoro na metal carbide mejupụtara na fim si n'ime na n'èzí na-eji nwayọọ nwayọọ mgbanwe metal ọcha, a na-akpọ MeC-Me film, diamond elu na film bụ a chemical nkekọ, naanị nke a Nchikota nwere ike melite nkekọ ike nke diamond, ma ọ bụ melite ike nke taya ahu nke diamond. Nke ahụ bụ, mkpuchi ahụ na-arụ ọrụ dị ka àkwà mmiri na-ejikọta n'etiti abụọ ahụ.
2. Meziwanye ike nke diamond.
N'ihi na kristal diamond na-enwekarị ntụpọ dị n'ime, dị ka microcracks, obere oghere, wdg, a na-akwụ ụgwọ ntụpọ ndị a dị n'ime kristal site na ijuputa akpụkpọ anụ MeC-Me. Ịkwasa akwa na-arụ ọrụ nke ịgba ume na ime ka ike sie ike. Kemịkalụ plating na plating nwere ike imeziwanye ike nke ngwaahịa dị ala, ọkara na elu.
3. Jiri nwayọọ na-ekpo ọkụ ọkụ.
Ihe mkpuchi ígwè dị nwayọọ karịa nke abrasive diamond. The egweri okpomọkụ na-agafere resin adịgide adịgide gị n'ụlọnga na kọntaktị na-egweri urughuru, nke mere na ọ na-ọkụ si ozugbo elu okpomọkụ mmetụta, ka ịnọgide na-ejigide ike na diamond abrasive.
4. Mwepu na mmetụta nchebe.
N'oge oke okpomọkụ sintering na egweri na elu okpomọkụ, mkpuchi oyi akwa kewapụrụ na-echebe diamond iji gbochie graphitization, oxidation ma ọ bụ ndị ọzọ chemical mgbanwe.
