Electroplated diamond maturusi anosanganisira akawanda maitiro mukugadzira maitiro, chero maitiro haana kukwana, achaita kuti iyo coating iwire pasi.
Mhedzisiro ye pre-plating kurapwa
Maitiro ekurapa esimbi matrix asati apinda muplating tank anonzi pre-plating kurapwa. Pre-plating kurapwa kunosanganisira: mechanical polishing, kubvisa mafuta, kukukurwa uye activation matanho. Chinangwa chepre-plating kurapwa ndechekubvisa burr, mafuta, oxide firimu, ngura uye oxidation ganda pamusoro pematrix, kuitira kuburitsa matrix simbi kuti ikure simbi lattice zvakajairika uye kugadzira iyo intermolecular inosunga simba.
Kana iyo pre-plating kurapwa isina kunaka, pamusoro pematrix ine firimu yakaonda kwazvo yemafuta uye oxide firimu, simbi yesimbi yematrix simbi haigone kuburitswa zvizere, izvo zvinotadzisa kuumbwa kwesimbi yekuputira uye matrix simbi, iyo inongori mechanical inlay, simba rinosunga rakashata. Naizvozvo, kushambidzika kwakashata kusati kwaputirwa ndicho chikonzero chikuru chekuputira.
Mhedzisiro yeplating
Iyo formula yeplating solution inobata zvakananga mhando, kuomarara uye kupfeka kuramba kwesimbi yekuputira. Iine akasiyana maitiro paramita, ukobvu, density uye kushushikana kweiyo yekuputira simbi crystallization inogona zvakare kudzorwa.
Pakugadzirwa kwedhaimondi electroplating zvishandiso, vanhu vazhinji vanoshandisa nickel kana nickel-cobalt alloy. Pasina pesvedzero yekuputira tsvina, izvo zvinokonzeresa kudonha kwekuvhara ndezvi:
(1) Kupesvedzera kwekushushikana kwemukati Kushushikana kwemukati kwejasi kunogadzirwa mukuita kwe electrodeposition, uye izvo zvinowedzera mumhepo yakanyungudika uye zvigadzirwa zvavo zvekuora uye hydroxide zvichawedzera kushushikana kwemukati.
Kushungurudzika kweMacroscopic kunogona kukonzera mabhubhu, kuputika uye kudonha kubva pakuputira mukati mekuchengetedza uye kushandiswa.
Kune nickel plating kana nickel-cobalt alloy, kushushikana kwemukati kwakasiyana zvakanyanya, iyo yakakwirira iyo chloride yemukati, iyo yakakura kushushikana kwemukati. Kune munyu mukuru we nickel sulfate coating solution, kushushikana kwemukati we watt coating solution ishoma pane yeimwe coating solution. Nekuwedzera organic luminent kana kusagadzikana inobvisa mumiriri, iyo macro yemukati kushushikana kwejasi inogona kuderedzwa zvakanyanya uye iyo microscopic yemukati kushushikana inogona kuwedzera.
(2) Mhedzisiro yehydrogen evolution mune chero plating mhinduro, zvisinei nehukoshi hwayo hwePH, panogara paine imwe huwandu hwemaion ehydrogen nekuda kwekuparadzaniswa kwemamorekuru emvura. Naizvozvo, pasi pemamiriro akakodzera, zvisinei nekuputira mune acidic, kwayakarerekera, kana alkaline electrolyte, pane kazhinji kunaya kwehydrogen mu cathode pamwe nekunaya kwesimbi. Mushure mekunge ma hydrogen ions adzikira pacathode, chikamu chehaidhirojeni chinobuda, uye chikamu chinopinda musimbi yematrix uye chakanamira muchimiro cheatomu yehydrogen. Iyo inokanganisa lattice, ichikonzera kushushikana kukuru kwemukati, uye zvakare inoita kuti iyo jasi ive yakanyanya kuremara.
Mhedzisiro yeplating process
Kana kuumbwa kwegadziriro ye electroplating uye mamwe maitiro ekugadzirisa maitiro asingabatanidzwi, kuparara kwesimba mukugadzirisa kwe electroplating ndicho chikonzero chakakosha chekurasikirwa kwekuputira. Iyo electroplating yekugadzira maitiro e electroplating diamond maturusi akasiyana zvakanyanya kubva kune mamwe marudzi e electroplating. Iyo plating process ye electroplating diamond maturusi anosanganisira isina chinhu plating (base), jecha coating uye thickening maitiro. Muchiitiko chega chega, pane mukana weiyo matrix inosiya mhinduro yeplating, ndiko kuti, kupera kwemagetsi kwenguva refu kana kupfupi. Naizvozvo, kushandiswa kwemaitiro anonzwisisika, maitiro anogona zvakare kuderedza kubuda kweiyo coating yekudurura chiitiko.
