Looska rivet ee shaabadaysan ayaa guud ahaan laga sameeyaa birta, oo loo yaqaan birta kaarboon. Birtu waa la tumaa ama la rogaa, midabkeeda dabiiciga ahna waa natiijada wax soo saarka. Si looga hortago miridhku, waxay u baahan tahay koronto. Is-xakamaynta birta-la'aanta ah - isku-duubidda nuts, si kastaba ha ahaatee, uma baahna koronto-samaynta. Birta, midabka korantada guud ahaan waxaa go'aamiya macaamilka, iyadoo ku xiran midabka ay rabaan. Waxa kale oo jira shuruudo loogu talagalay adkaysiga buufinta milixda. Qaar ka mid ah midabada korantada waxay u baahan yihiin adkaysi buufin milix ah, halka qaar kalena ay miridhku dhawr saacadood gudahood. Arrin kale ayaa ah in macmiilku uu doonayo inuu dhoofiyo alaabta. Dhoofintu guud ahaan waxay u baahan tahay dahaar deegaan ahaan u wanaagsan, qaarna gudaha, qaar baa sameeya, laakiin badidoodu maaha.
Electroplating-ka ugu badan ee loo isticmaalo nafsad ahaantiisa {{0}Qojinta lawska ee suuqa waa zinc buluuga ah ee deegaanka u fiican, maadaama ay u adkaysan karto tijaabooyinka buufinta milixda ilaa 72 saacadood, ama saddex maalmood. Noocan elektiroonigga ah wuxuu bixiyaa cimri dheer oo buufin milix ah. Nikkel cad, tusaale ahaan, waxa uu leeyahay adkaysi buufinta milixdu ka gaaban tahay, sida caadiga ah daxalaysa dhawr saacadood gudahood, oo aan ka badnayn 10 saacadood. Laakiin qaar ka mid ah dahaadhka nikkel-ka cad waa la saliidayn karaa, iyo wakhtiga buufinta milixda ee lawska rivet ee saliidda leh ayaa noqon kara mid dheer.
