Na farko shi ne, ƙarfe ba shi da abubuwan haɗawa, wanda ke adana kuɗin kayan, na biyu shine dumama gida da kashewa, wanda ke ɗaukar ɗan gajeren lokaci, don haka tasirin ceton makamashi yana da mahimmanci; sarrafa kansa ta kan layi yana ceton aiki, babu gurɓataccen mai, babu gurɓataccen iskar gas, har ma da ƙarin kare muhalli.

5. Sauya carburizing mai zurfi Carburizing tsari ne tare da dogon juyi da yawan amfani da wutar lantarki. A cikin ‘yan shekarun nan, ƙasashen waje sun yi nasarar yin amfani da murhun murhun murhu don maye gurbinsa. Fa’idodin sune: rage farashin ƙarfe, ceton kuzari, ceton ma’aikata (carburizing and cold working grinding), da rage murdiya.

Sabili da haka, ana iya yanke shawarar ƙarshe:

1) Ana kashe wutar saman kayan aikin ta hanyar shigar da wutar makera, wanda ke inganta juriya na kayan aikin asali.

2) Idan aka kwatanta da sassan da aka kashe na yau da kullun, shigar da murhun murhun wuta sun inganta ingantaccen juriya saboda tsananin taurin ƙasa kuma babu decarburization.

3) Rashin jurewa na shigar da murhun wutar murhun wuta wanda aka ƙera da ƙananan ƙarfe na carbon ya yi ƙasa da na sassan carburized saboda ƙarancin taurin ƙasa da abun cikin carbon.
