Phekolo ea holim'a gear e sebetsoa ho ntlafatsa boemo ba holim'a thepa.Ka kakaretso, ho na le kalafo e ntšo (ka holim'a oxidation), kalafo e tiileng ea ho tlotsa, galvanizing, kalafo ea phosphorurative, plating ea silevera ea lik'hemik'hale, le kalafo ea bokaholimo ba mahlaseli.Litšobotsi tsa bona tsa litšobotsi tsa bona Tlhaloso e tjena

1. Phekolo e lefifi (oxidation ea bokaholimo):

Bakeng sa phekolo e ntšo ea alkaline: Ha o kenya tšepe ka tharollo ea alkaline ho 14ctc, tšepe ka boeona e bapala lik'hemik'hale 'me e etsa filimi e ntšo ea letlalo holim'a eona.Botenya ba cortex e ntšo bo ka tlase, 'me metsoako ea lik'hemik'hale ke tse' nè - iron oxidation.Cortex e na le phello e khahlanong le mafome.

2. Kalafo e tiileng ea ho tlotsa:

Feela fafatsa lubricant e tiileng holim'a leino la lebili la gear, le lubricant e khomarelang holimo ho omella ho etsa filimi ea letlalo.Likaroloana tsa distan sulfide tse ka har'a metsoako ea lubricant li kenella ka har'a lisele tsa tšepe ho bapala phello ea lubrication.Haholo-holo ts'ebetsong ea pele ea likere kapa ho thibela phello ea eona ea lubrication ho micro-movement e bakoang ke metsamao e menyenyane ea likhohlano.Hangata e sebelisoa sebakeng seo oli e tlotsang e ke keng ea sebelisoa

3. Sesetiloe:

Phekolo ea holim'a metsi ka morero oa ho ntlafatsa ts'ebetso e khahlanong le mafome ea tšepe.Ka tsoelo-pele ea kalafo ea rhinate passivation, ts'ebetso ea ponahalo le eona e ntlafetse haholo.Botenya ba lera la plating bo fapane, hangata bo ka ba 225 μm.

4. Phekolo ea Phosphorusization:

Bakeng sa phekolo ea phosphate: Metal e qoelisoa ka tharollo ea phosphate e futhumatsang bakeng sa phekolo ea lik'hemik'hale, e le hore bokaholimo ba tšepe bo thehe lera le sireletsang phosphate.Thibelo e khahlanong le mafome ea cortex ea phosphorized e na le phello e ntle ea abrasion le phello ea lubrication, kahoo e sebelisoa haholo ho phekola likarolo tse thellang.

5. Ho roala silevera ka lik'hemik'hale:

Khanyetso ea kutu ea lik'hemik'hale tsa plating / abrasion resistance e phahame, 'me mokhoa oa silevera-plated ha o fetise motlakase le electrolytic.E loketse lihlahisoa tse nang le litlhoko tse phahameng tsa boholo le ho nepahala le libopeho tse rarahaneng.

6. Kalafo ea bokaholimo ba mahlaseli:

Kalafo ea Raydent e sebelisa mokhoa o ts'oanang le oa electroplating ho hlahisa filimi e makhethe ea 1 ~ 2 μm e ntšo e nang le oxidized ka holim'a thepa ea 'mè.Hobane filimi ea letlalo le buka ea tšepe ea T, ho thata haholo ho e hlakola.Bokhoni ba ho hanyetsa mafome bo matla / bo sa senyeheng bo a ntlafatsoa, ​​​​'me 'mala o motšo.

Hlokomela:

1. E angoa ke sebōpeho le boholo, cortex e ke ke ea etsoa ka mokhoa o tšoanang ka har'a motso oa meno.

2. Liketsahalo tse tsamaellanang tsa ROHS li hloka ho hlakisoa ka ho hlaka ho hlakisa hore phekolo ea hexagonal chromium e hloka ho tlosoa.
