1. Ukukhulelwa

Amalungu e-metallurgy yomgubo ngokwendalo aneeporeji.I-impregnation, ebizwa ngokuba yi-penetration, ibandakanya ukuzaliswa kweepores ezininzi: iplastiki, i-resin, ubhedu, ioli, enye into.Ukubeka icandelo le-porous phantsi koxinzelelo kunokubangela ukuvuza, kodwa ukuba umithisa inxalenye, iya kuba yingcinezelo.Izinto ezisetyenziselwa ukumitha inxalenye ixhomekeke kwizinto ezifana neendleko kunye nesicelo.Ukuntywiliselwa kwe-oyile kuvumela iindawo ukuba zithambise ngokuzenzekelayo.Yonke into ixhomekeke kwiimfuno zakho zoyilo.

2. Electroplating

Plating yenye indlela intsimbi stainless iimfuno zobuhle okanye ukusebenza - ukwenza inxalenye ebonakalayo nomtsalane kunye nokuphucula ukuxhathisa umhlwa etc. Plating ikunika ezi mpawu lo gama ikuvumela ukuba "sandwich" imathiriyeli zitshiphu kwinxalenye yokuqala.

3. Ukuchama ngeembumbulu

I-shot peening yinkqubo yoxinaniso lwendawo ephucula umphezulu wenxalenye ngokususa ii-burrs kunye nokusebenzisa uxinzelelo olucinezelayo kwindawo.Oku kunokuba luncedo kwizicelo ezithile zokudinwa.I-Sandblasting nayo yenza iipokotho ezincinci ezibamba i-lubricant phezu kwendawo.Ukudinwa kukuqhekeka kudla ngokuqala ngenxa yeziphene ezingaphezulu.Ukuchama ngokudubula kunokuthintela ngokufanelekileyo ukwakheka kweentanda zomhlaba kwaye kunokulibazisa ukuphuhliswa kweentanda ezininzi.

4. Unyango lomphunga

Xa isetyenziswe kwizinto ezisekelwe kwintsimbi, unyango lwe-steam ludala umaleko obhityileyo, oqinileyo we-oxide.Umaleko weoksidi awudusi;yinto encamathela kwintsimbi.Olu luhlu lunokuphucula: ukuxhathisa i-corrosion, ukumelana noxinzelelo, ubunzima
