Stability ntawm mature patina (12-24 lub hlis tom qab tsim)
Tom qab lub patina tag nrho matures mus rau hauv ib tug ntom, ruaj oxide zaj duab xis nruj nreem khi rau steel nto, nws tsim ib tug ruaj khov tiv thaiv. Lub hauv paus xim liab - xim av yuav tsis ploj mus, tshuaj dawb lossis tig daj ntseg txawm tias tom qab xyoo raug cua, los nag, tshav ntuj thiab me ntsis atmospheric corrosion. Cov patina cov xim tsuas yog tsim me ntsis, ntuj mellowing lub sijhawm (tsaus lossis nplua nuj lub suab), uas yog ib txwm muaj kev laus thiab txhim kho nws txoj kev zoo nkauj es tsis yog "faj".
Tsis muaj fading nyob rau hauv ib puag ncig sab nraum zoov
Nyob rau hauv cov qauv hauv nroog, nyob deb nroog, vaj lossis thaj chaw sov me me ntawm ntug dej hiav txwv (ntau dua 1km ntawm hiav txwv), cov laus patina cov xim ruaj khov yog tag nrho lav. Cov ntsiab lus hlau (Cu/Cr/Ni) hauv SPA-H steel tsim cov tshuaj muaj zog oxide nyob rau hauv patina, uas tiv thaiv UV hluav taws xob, los nag ntxuav thiab kub hloov, tshem tawm cov kev pheej hmoo ntawm cov xim los yog fading uas plagues pleev xim rau / coated hlau cov khoom.
Kev hloov xim me me hauv ib puag ncig hnyav (tsis fading)
Nyob rau hauv siab - thaj chaw ntug dej hiav txwv ntsev, hnyav thaj chaw muaj kua qaub pos huab lossis siab - qhov chaw kaw ntom nti, patina yuav tsis ploj mus tab sis yuav muajlub zos tsis sib xws(vim me ntsis pitting corrosion) los yog nyias greyish nto txheej (los ntawm plua plav / kev lag luam residue tsub zuj zuj). Cov no tsis yog fading phenomena-lawv tuaj yeem txhim kho tau yooj yim los ntawm kev yaug dej yaug dej (rau plua plav) lossis nyias pob tshab sealer (rau hnyav corrosion), thiab cov tub ntxhais reddish - xim av patina tseem nyob hauv qab.
Qhov laj thawj tseem ceeb rau tsis yog -fading: cov yam ntxwv ntawm SPA-H patina
Tsis zoo li cov xim pleev xim / txheej xim uas zaum saum cov hlau thiab tev / ploj vim yog kev yaig ib puag ncig, SPA-H patina yog ib qhometallurgically bonded oxide txheejtsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau sab hauv alloy ntsiab nrog rau sab nraud ib puag ncig. Nws loj hlob los ntawm cov hlau saum npoo sab nraud thiab yog ib feem tseem ceeb ntawm lub hauv paus hlau, yog li nws tsis tuaj yeem raug ntxuav los yog ploj mus los ntawm lwm yam, thiab txawm tias qhov kev puas tsuaj me tuaj yeem ua rau nws tus kheej - kho kom rov zoo li qub xim thiab qauv.
