Ntucha Nickel Na-egbuke egbuke nke 1149

▪ Usoro a na-egosipụta ike ịtụba ihe pụrụ iche, na-eme ka a na-etinye otu ihe n'ime ya ọbụna n'ime geometry dị mgbagwoju anya na oghere miri emi. A na-ejigide iguzosi ike n'ihe ịsa ahụ ruo ogologo oge, yana obere mmebi nke ihe mgbakwunye organic, nke na-eme ka ịdị mma nke mkpuchi ahụ dịgide. Usoro electrolyte gụnyere ihe na-eme ka ìhè na ihe ndị na-eme ka ọkwa dị elu nke na-eme ka ike ịtụba ihe dịkwuo mma, na-eme ka elu ahụ dị nro ma na-egosipụta.

▪ Usoro a dabara na nhazi ihe mkpuchi rack na gbọmgbọm, na-enye ohere iji jikwaa nha na olu dị iche iche nke ihe eji arụ ọrụ. Bath ahụ na-arụ ọrụ nke ọma n'ime oke okpomọkụ sara mbara, nke na-adịkarị n'etiti 45°C ruo 65°C, nke enwere ike ịgbanwe dabere na ihe achọrọ maka ngwa. A na-achịkwa ọkwa pH nke ọma n'ime oke dị warara, nke na-abụkarị n'etiti 3.8 ruo 4.5, iji mee ka ọnụego ihe eji etinye na ihe mkpuchi dịkwuo mma.

▪ A na-ejigide mkpokọta ion nickel dị na mmiri ọgwụ ahụ n'ime 70 ruo 90 g/L, ebe a na-edebe ion chloride n'etiti 10 ruo 20 g/L iji hụ na anode na-emebi emebi ma na-eduzi ya nke ọma. Ojiji nke anod nickel dị ọcha nke ukwuu, tinyere akpa anode, na-ebelata ntinye nke ihe na-adịghị ọcha na ihe ndị na-adịghị mma n'ime bat ahụ.

▪ Usoro a gụnyere sistemụ nzacha dị elu, nke na-ejikarị katrij nzacha micron 5 ruo 10, iji wepụ ihe siri ike ọ bụla a kwụnyere ma nọgide na-edobe ịdị ọcha nke bat. A na-eme nnwale mkpụrụ ndụ Hull mgbe niile iji nyochaa arụmọrụ bat ahụ ma gbanwee njupụta mgbakwunye dịka ọ dị mkpa. Ductility nke oyi akwa nickel echekwara na-agafekarị 8%, dịka a tụrụ ya site na ule spiral contracometer, na-ahụ na arụmọrụ dị mma na ọrụ nhazi post-plating.

▪ Enwere ike ịhazi ike mkpuchi ahụ site na 250 ruo 450 HV site na ịgbanwe paramita bat na oke mgbakwunye, na-eme ka ọ dabara adaba maka ọtụtụ ọrụ ụlọ ọrụ mmepụta ihe. Usoro a na-egosi njirimara njikọta dị mma, yana ule ike peel na-agabiga 8 N/mm² mgbe niile. Nguzogide nchara nke nkwụnye nickel, dịka nyocha nnu si enyocha, na-agafekarị awa 96 ruo nchara ọcha na awa 200 ruo nchara uhie mgbe ejiri ya mechie nke ọma.

▪ Ike ịtụba ihe dị iche iche nke bat ahụ, nke na-agafekarị 80% dịka mkpụrụ ndụ Haring-Blum si tụọ, na-eme ka ọkpụrụkpụ mkpuchi ahụ dị otu. Usoro a dị irè karịsịa maka akụkụ dị elu, yana mgbanwe ọkpụrụkpụ na-adịkarị obere karịa 15% n'ofe ọrụ ahụ. Nrụgide dị ala nke nkwụnye ahụ, nke na-adịkarị n'okpuru 10 MPa dịka a tụrụ site na ihe nhazi spiral contracometer, na-ebelata ihe ize ndụ nke mgbawa ma ọ bụ delamination.

▪ Usoro a gụnyere sistemụ nlekota oge maka paramita dị mkpa dịka okpomọkụ, pH, na ntinye ígwè, na-eme ka mma mkpuchi ahụ dị mma. Ojiji nke ihe mgbakwunye organic dị elu nwere ihe ndị na-achịkwa onwe ha na-eme ka ndụ ịsa ahụ dịkwuo ogologo, na-agafekarị 12 MTO (mgbanwe ígwè) na-enweghị mmebi dị ukwuu na mma mkpuchi. Emebere usoro a iji mezuo ụkpụrụ ụlọ ọrụ siri ike, gụnyere nkọwapụta ASTM B689 na ISO 1456 maka mkpuchi nickel nwere elektrọd.
