Ngwá ọrụ diamond electroplated na-agụnye ọtụtụ usoro na usoro mmepụta ihe, usoro ọ bụla ezughị ezu, ga-eme ka mkpuchi ahụ daa.
Mmetụta nke ọgwụgwọ a na-ebute ụzọ
A na-akpọ usoro ọgwụgwọ nke matrix ígwè tupu ịbanye na tankị nke a na-akpọ ọgwụgwọ tupu ịmalite. Ọgwụgwọ tupu ịtinye ihe na-agụnye: nchacha igwe, iwepụ mmanụ, mbuze na usoro ịgbalite. Ebumnobi nke ọgwụgwọ tupu plating bụ iji wepụ burr, mmanụ, oxide film, nchara na oxidation akpụkpọ n'elu nke matriks, ka ikpughe na matrix metal na-eto eto lattice metal na-emekarị na-etolite intermolecular njikọ ike.
Ọ bụrụ na ọgwụgwọ tupu plating adịghị mma, elu nke matriks ahụ nwere ihe nkiri mmanụ dị ezigbo mkpa na ihe nkiri oxide, àgwà metal nke metal matrix enweghị ike ikpughe n'ụzọ zuru ezu, nke ga-egbochi nhazi nke mkpuchi mkpuchi na metal matrix, nke bụ naanị ihe ntinye n'ibu, ike na-ejikọta ya adịghị mma. Ya mere, pretreatment na-adịghị mma tupu plating bụ isi ihe na-akpata mkpuchi mkpuchi.
Mmetụta nke plating
Usoro nke plating ngwọta na-emetụta kpọmkwem ụdị, ike ike na eyi iguzogide metal mkpuchi. Na usoro usoro dị iche iche, a pụkwara ịchịkwa ọkpụrụkpụ, njupụta na nrụgide nke mkpuchi metal crystallization.
Maka mmepụta nke ngwaọrụ electroplating diamond, ọtụtụ ndị na-eji nickel ma ọ bụ nickel-cobalt alloy. Na-enweghị mmetụta nke ịkwanye adịghị ọcha, ihe ndị na-emetụta mkpuchi mkpuchi bụ:
(1) Mmetụta nke nrụgide dị n'ime A na-emepụta nrụgide dị n'ime nke mkpuchi na usoro nke electrodeposition, na ihe mgbakwunye na ebili mmiri na-agbaze na ngwaahịa ha na-emebi emebi na hydroxide ga-eme ka nrụgide dị n'ime ahụ dịkwuo elu.
Nchegbu macroscopic nwere ike ime ka afụ, mgbawa na ịdaba na mkpuchi na usoro nchekwa na ojiji.
Maka nickel plating ma ọ bụ nickel-cobalt alloy, nrụgide dị n'ime ahụ dị nnọọ iche, ka ọdịnaya chloride dị elu, ka nrụgide dị n'ime ahụ dịkwuo ukwuu. Maka isi nnu nke ngwọta mkpuchi nickel sulfate, nrụgide dị n'ime nke ngwọta mkpuchi watt dị obere karịa nke ngwọta mkpuchi ndị ọzọ. Site n'ịgbakwunye organic luminent ma ọ bụ nrụgide na-ewepụ onye na-ahụ maka ya, enwere ike ibelata nrụgide dị n'ime macro nke mkpuchi ma nwee ike ịbawanye nrụgide n'ime microscopic.
(2) Mmetụta nke evolushọn hydrogen na ngwọta ọ bụla nke plating, n'agbanyeghị uru PH ya, a na-enwekarị ion hydrogen n'ihi nkwụsị nke mkpụrụ ndụ mmiri. Ya mere, n'okpuru ọnọdụ kwesịrị ekwesị, n'agbanyeghị agbanye na acidic, neutral, ma ọ bụ alkaline electrolyte, a na-enwekarị mmiri ozuzo hydrogen na cathode yana mmiri ozuzo ígwè. Mgbe ion hydrogen belatara na cathode, akụkụ nke hydrogen na-agbanarị, akụkụ ya na-abanyekwa na metal matrix na mkpuchi na steeti hydrogen atomiki. Ọ na-agbagọ lattice, na-akpata nnukwu nrụgide dị n'ime, ma na-emekwa ka mkpuchi ahụ gbanwee nke ọma.
Mmetụta nke plating usoro
Ọ bụrụ na a na-ewepụ ihe mejupụtara nke ngwọta electroplating na mmetụta ndị ọzọ na-achịkwa usoro, ọdịda ike na usoro electroplating bụ ihe dị mkpa na-akpata ọnwụ mkpuchi. Usoro mmepụta nke electroplating nke ngwaọrụ diamond electroplating dị nnọọ iche na ụdị electroplating ndị ọzọ. Usoro plating nke electroplating diamond ngwaọrụ gụnyere ihe efu plating (isi), ájá mkpuchi na ndim usoro. Na usoro nke ọ bụla, enwere ike ịnweta matriks na-ahapụ ihe ngwọta plating, ya bụ, nkwụsị ọkụ ogologo ma ọ bụ mkpụmkpụ. Ya mere, iji usoro ndị ọzọ ezi uche dị na ya, usoro nwekwara ike ibelata mpụta nke mkpuchi ịwụfu onu.
