Fasahar rufewa ta Laser: wani gagarumin ci gaba a fannin kariyar lalata jiragen ruwa
Tsatsar jiragen ruwa ta kasance babban ƙalubale a masana'antar jigilar jiragen ruwa ta duniya. A cewar kididdiga, asarar tattalin arziki kai tsaye a duniya sakamakon tsatsar jiragen ruwa ta wuce dala biliyan 100 a kowace shekara. Iyakokin aikin shafan gargajiya na hana tsatsa a cikin yanayin ruwa mai tsanani sun sanya neman ƙarin fasahar kariya mai zurfi ya zama babban buƙata. Fasahar rufewa ta Laser, tare da keɓaɓɓun halayen haɗin ƙarfe, tana kawo sauyi a fannin kariyar tsatsar jiragen ruwa.
Iyakokin Fasahar Yaƙi da Tsatsa ta Gargajiya
A halin yanzu, rufin hana lalata na yau da kullun yana fuskantar manyan ƙalubale guda uku a cikin yanayin ruwa:
Lokacin kariya na ɗan gajeren lokaci: Rufin da aka saba amfani da shi yana ba da kariya mai inganci kawai na tsawon shekaru 1-10 a cikin yanayin ruwa, yana buƙatar kulawa akai-akai;
Rashin ƙarfin haɗin kai: Ƙarfin haɗin da aka yi da rufi-zuwa-ƙasa shine kawai 3-6 MPa, wanda hakan ke sa ya zama mai sauƙin barewa a ƙarƙashin tasirin injiniya;

Tushen waɗannan matsalolin yana cikin rashin iyawar hanyoyin kariya na gargajiya na "rufin jiki" don jure wa yanayin ruwa mai rikitarwa. Lokacin da fashewar micron-scale ta bayyana a cikin murfin, ions na chloride suna shiga cikin sauri, suna haifar da ramuka, tsatsa, da sauran matsaloli.
Nasarar Fa'idodin Fasahar Rufe Laser
Fasahar rufe laser tana amfani da laser mai ƙarfi don haɗa foda na ƙarfe nan take tare da substrate, wanda ke samar da haɗin ƙarfe. Wannan fasaha tana ba da fa'idodi uku masu mahimmanci:
Ƙarfin Haɗin Kai Mai Kyau: Layin rufewa yana cimma haɗin matakin atomic tare da substrate, tare da ƙarfin haɗin ≥200 MPa, fiye da sau 35 fiye da rufin gargajiya, yana kare shi sosai daga tasirin raƙuman ruwa.
Tsawon Rayuwar Kariya Mai Tsawo: Kwaikwayon dakin gwaje-gwaje sun nuna juriyar tsatsa fiye da shekaru 50, wanda ya zarce na rufin gargajiya.
Tsarin Samarwa Mai Kyau ga Muhalli: Ta amfani da kayan ƙarfe marasa VOC, duk tsarin aikace-aikacen ba ya fitar da abubuwa masu cutarwa.
Wannan "haɗin ƙarfe" yana canza layin kariya daga wani abu mai sauƙi na saman zuwa wani ɓangare na ƙarfen tushe, yana canza tsarin kariya ta asali.
Fa'idodin Tattalin Arziki na Aikace-aikacen Aiki
Wannan fasaha ta nuna muhimmancin tattalin arziki a aikace-aikace masu amfani:
Rage Kuɗin Kulawa Mai Muhimmanci: Ana amfani da shi wajen gyaran tankunan ballast akan manyan motocin ɗaukar kaya masu nauyin tan 200,000, gyara ɗaya zai iya ceton Yuan 800,000 a asarar lokacin aiki;
Ingantaccen Ingancin Kayan Aikin Wutar Lantarki ta Iska: Amfani da hasumiyoyin gonakin iska a yankin da ake fesawa a bakin teku ya rage farashin kulawa na shekara-shekara da kashi 60%;
Ingantaccen Aikin Kayan Aikin Teku Mai Zurfi: Rufin da aka yi amfani da shi wajen haƙa ƙafafuwa masu haƙa rami ya ƙara juriyar buguwa sau uku.
Hasashen Ci gaban Masana'antu
Fasahar Laser cladding tana da fa'idodi masu yawa na aikace-aikace a cikin kariyar lalata jirgin ruwa:
Karya Shingayen Fasaha: Keta iyakokin fasaha na rufin ruwa mai inganci;
Canza Tsarin Gyara: Canjawa daga "Kulawa na Lokaci-lokaci" zuwa "Kariya ta Dogon Lokaci";
Tallafawa Dabarun Kare Muhalli: Tsarin kore yana taimaka wa masana'antar jigilar kaya ta cimma burinta na rage gurɓatar iskar carbon.
Tare da ci gaban tattalin arzikin teku na duniya, ana sa ran wannan fasaha za ta samar da darajar kasuwa fiye da yuan biliyan 5. Masana masana'antu sun nuna cewa: "Wannan ba wai kawai wani sabon abu ne a fannin fasahar kayayyaki ba, har ma da sake fasalta manufar kariyar kayan aikin ruwa." Fasahar rufe kayan laser tana ƙirƙirar "sulke na ƙarfe" na gaske ga jiragen ruwa, tana samar da ingantattun hanyoyin magance tsatsa ga masana'antar jigilar kayayyaki ta duniya.
