Sabili da haka, saman lu'u-lu'u yana da halaye na ƙarfe, wanda zai iya inganta rayuwar sabis da ingantaccen aiki na kayan aikin lu'u-lu'u. Asalinsa shine sanya abubuwan haɗin gwiwa irin su Ti ko gariyar sa mai rufi kai tsaye akan saman lu'u-lu'u, ta hanyar dumama sama da dumama magani, ta yadda saman lu'u-lu'u ya zama nau'in haɗin haɗin sinadarai iri ɗaya.
By shafi lu'u-lu'u nika barbashi, da dauki na shafi da lu'u-lu'u zuwa metalize lu'u-lu'u saman. A daya hannun, da metallized lu'u-lu'u surface da karfe jiki dauri wakili tsakanin karfe metallurgical hade, sabili da haka, shafi jiyya na lu'u-lu'u ga sanyi matsa lamba ruwa sintering da zafi m lokaci sintering yana da fadi applicability, don haka taya jiki gami ga lu'u-lu'u nika hatsi ƙarfafawa ya karu, rage lu'u-lu'u kayan aiki a cikin yin amfani da nika kashe, don inganta sabis rayuwa da kuma yadda ya dace da lu'u-lu'u kayan aikin.

5. Menene babban ayyuka na maganin lu'u-lu'u lu'u-lu'u?

1. Inganta ikon inlay na jikin tayi don saka lu'u-lu'u.
Saboda faɗaɗa zafin zafi da ƙanƙantar sanyi, ana haifar da matsananciyar zafi a cikin wurin tuntuɓar lu'u-lu'u da jikin taya, wanda zai sa lu'u-lu'u da bel ɗin haɗin jikin tayi ya samar da ƙananan layukan, don haka rage ƙarfin jikin taya mai rufi da lu'u-lu'u. Na lu'u-lu'u surface shafi iya inganta jiki da kuma sinadaran Properties na lu'u-lu'u da kuma jiki dubawa, ta hanyar makamashi bakan bincike, tabbatar da cewa karfe carbide abun da ke ciki a cikin fim daga ciki zuwa waje ne sannu a hankali canzawa zuwa karfe abubuwa, da ake kira MeC-Me film, lu'u-lu'u surface da kuma fim ne wani sinadaran bond, kawai wannan hade iya inganta bond ikon na lu'u-lu'u, ko inganta ikon taya jiki na lu'u-lu'u. Wato rufin yana aiki azaman gada mai ɗaure tsakanin su biyun.
2. Inganta ƙarfin lu'u-lu'u.
Saboda lu'ulu'u na lu'u-lu'u sau da yawa suna da lahani na ciki, kamar microcracks, ƙananan cavities, da dai sauransu, waɗannan lahani na ciki a cikin lu'ulu'u ana biya su ta hanyar cika MeC-Me membrane. Plating yana taka rawar ƙarfafawa da ƙarfafawa. Kemikal plating da plating na iya inganta ƙarfin ƙananan, matsakaici da manyan samfurori.
3. Rage zafin zafi.
Rufin ƙarfe yana da hankali fiye da na lu'u-lu'u abrasive. The nika zafi ne wuce zuwa guduro dauri wakili a lamba tare da nika barbashi, sabõda haka, an ƙone daga nan take high zafin jiki tasiri, don kula da ta riƙe ƙarfi a kan lu'u-lu'u abrasive.
4. Warewa da tasirin kariya.
A lokacin babban zafin jiki sintering da nika a high zafin jiki, shafi Layer raba da kuma kare lu'u-lu'u don hana graphitization, hadawan abu da iskar shaka ko wasu sinadaran canje-canje.
