KUMALIZA
Kutentha mankhwala
Kutentha mankhwala ndi mtundu wa zitsulo matenthedwe processing luso.Zomwe zimapangidwira pang'onopang'ono zimakwaniritsa kapangidwe kake ndi magwiridwe antchito kudzera pakutenthetsa, kuteteza kutentha ndi kuziziritsa m'malo olimba.Njira zochizira kutentha kwachitsulo zitha kugawidwa m'magulu atatu: chithandizo cha kutentha kwathunthu, chithandizo cha kutentha pamwamba ndi chithandizo cha kutentha kwa mankhwala.Kawirikawiri, mawonekedwe a ziwalozo ndi mankhwala onse sasintha.Mwa kusintha ma microstructure amkati mwa zigawozo, kapena kusintha mawonekedwe a mankhwala a pamwamba pa zigawozo, ntchito yogwiritsira ntchito zigawozo zikhoza kusintha.Makhalidwe ake ndi kupititsa patsogolo ubwino wa mkati mwa ziwalo, zomwe nthawi zambiri siziwoneka.
Oxidized Blackandi Black Anodized
Chithandizo cha Oxidized Black ndi njira yodziwika bwino yopangira mankhwala pamwamba.Mfundo yake ndi kupanga filimu ya oxide pamwamba pazitsulo kuti isungunuke mpweya ndikukwaniritsa cholinga chopewa dzimbiri.Chithandizo chakuda chingagwiritsidwe ntchito ngati mawonekedwe akufunika sali apamwamba.Chithandizo chakuda pamwamba pazigawo zachitsulo chimatchedwanso blued.Anodizing ndi electrochemical oxidation ya zitsulo kapena aloyi.Aluminiyamu ndi aloyi ake kupanga wosanjikiza filimu okusayidi pa zotayidwa zinthu zotayidwa (anode) pansi pa ntchito panopa pansi lolingana electrolyte ndi zinachitikira ndondomeko.Ngati anodizing sanatchulidwe, nthawi zambiri amatanthauza sulfuric acid anodizing.
Pkukonza
Kupukuta kumatanthawuza kugwiritsa ntchito makina, mankhwala kapena electrochemical zotsatira kuti achepetse kuuma kwa pamwamba pa workpiece kuti apeze malo owala komanso osalala.Ndi ntchito zida kupukuta ndi abrasive particles kapena zina kupukuta TV kusintha pamwamba workpiece.
Nitriding
Chithandizo cha nitriding chimatanthawuza njira yopangira kutentha kwa mankhwala komwe maatomu a nayitrogeni amalowa pamwamba pa chogwirira ntchito mu sing'anga inayake pa kutentha kwina.Zogulitsa za nitrided zimakhala ndi kukana kwamphamvu kwambiri, kukana kutopa, kukana dzimbiri komanso kukana kutentha kwambiri.Chitsulo chokhazikika cha nitrided chokhala ndi aluminiyamu chikhoza kupeza kuuma kwakukulu ndi kusanjikiza kwapamwamba kwambiri pambuyo pa nitriding, koma wosanjikiza wake ndi wosasunthika kwambiri.M'malo mwake, chitsulo chokhala ndi chromium chokhala ndi aloyi otsika chimakhala cholimba chocheperako, koma chosanjikizacho chimakhala cholimba kwambiri, ndipo pamwamba pake chimakhala ndi kukana kwamphamvu komanso kukana dzimbiri.
