HVOF yana fesa murfin Al-SiC akan ma'aunin ma'aunin magnesium don jirgin sama, wanda zai iya haɓaka juriya.

2. Masana'antar Karfe da Mai

Masana'antar ƙarfe da karafa wani muhimmin fanni ne na aikin feshin zafi, kuma shi ne na biyu mafi girma a masana'antu a kasar Sin bayan aikin feshin zafi a masana'antar sufurin jiragen sama. A shekarar 2009, danyen karfen da kasar Sin ta fitar ya kai kashi 47% na yawan danyen karfen da ake fitarwa a duniya. Ƙasar ƙarfe ce ta gaske, amma ba gidan wutar lantarki ba ce. Wasu karafa masu inganci har yanzu suna buƙatar shigo da su da yawa. Daya daga cikin dalilan da ya fi muhimmanci shi ne yadda ba a yin amfani da feshin zafi na kasar Sin a masana'antar karafa. Irin su fashewa makera tuyere, high-zazzabi annealing makera abin nadi, zafi abin nadi farantin isar abin nadi, goyon bayan abin nadi, straightening abin nadi, galvanized dagawa abin nadi, nutse abin nadi, da dai sauransu A amfani da thermal fesa shafi a kan wadannan aka gyara iya ƙwarai inganta aiki yadda ya dace da kuma aiki yadda ya dace rage farashin, Inganta ingancin samfuran, kuma fa'idodin suna da mahimmanci 19-0.

A taron ITSC na 2011, kwararre na Japan Namba ya binciki haƙƙin mallaka da ke da alaƙa da aikace-aikacen feshin zafi a cikin masana'antar ƙarfe a duniya. Sakamakon binciken ya nuna cewa, daga shekarar 1990 zuwa 2009, mallakar mallakar kasar Japan ya kai kashi 39%, Amurka tana da kashi 22 cikin 100, da kaso 17 cikin dari na kasashen Turai, da kaso 9% na kasar Sin, da kaso 6% na Koriya ta Kudu, kasar Rasha ta kai kashi 3. %, haƙƙin mallaka na Brazil yana da kashi 3%, kuma haƙƙin mallaka na Indiya yana da kashi 1%. Idan aka kwatanta da kasashen da suka ci gaba kamar Japan, Turai, da Amurka, aikin feshin zafi a masana'antar karafa a kasar Sin ya ragu, kuma sararin ci gaba yana da yawa.

Cikakkun rahotannin da suka shafi taron sun kuma haɗa da NiCrAlY da YO foda a matsayin albarkatun ƙasa, NiCrAlY-Y0 an shirya foda ta hanyar agglomeration sintering da hanyoyin hadawa, kuma an shirya sutura ta HVOFDJ2700 bindiga. Kwaikwayi anti-gina na makera Rolls a cikin karfe masana'antu. Sakamakon binciken ya nuna cewa murfin foda da aka shirya ta hanyar agglomeration sintering yana da kyakkyawan juriya na gina jiki na manganese oxide, amma rashin juriya ga haɓakar ƙarfe oxide. Rubutun da aka shirya daga cakuda foda.

Thermal spraying fasahar da ake amfani da ko'ina a gas, man bututun, da kuma ƙofar bawul surface fesa anti-lalata da lalacewa-resistant coatings, mafi yawan su HVOF fesa WC10Co4Cr shafi.

3. Sabbin makamashi, sabbin kayan aiki, da injin turbin gas

Kwayoyin man fetur mai ƙarfi (SOFCs) an tsara su a cikin jagorancin faranti da faranti na bakin ciki, gami da anodes, electrolytes, cathodes,da matakan kariya. A halin yanzu, ƙirar kayan aiki da fasaha na samar da ƙwayoyin man fetur mai ƙarfi sun girma, kuma babbar matsala ita ce matsalar shiri. Fasahar fesa thermal (ƙananan feshin plasma mai ƙarfi, feshin ƙwayar ƙwayar cuta) ta zama fasaha mafi shahara. Nasarar aikace-aikacen feshin zafi akan SOFC shine sabon aikace-aikacen fasahar feshin zafin jiki a cikin sabbin makamashi, kuma yana haɓaka haɓakar abubuwan feshi masu alaƙa. Misali, plasma da aka fesa kayan feshin LaSrMnO (LSM), kamfanin HC.Starck na Jamus ya riga ya fara samarwa da siyar da wannan kayan da kayan da suka danganci. Masu binciken sun kuma yi amfani da feshin plasma na ruwa-ruwa don shirya kayan lantarki na LiFePO don batir lithium-ion. rahotannin bincike masu alaka.

Haɓaka fasahar feshin thermal ba za a iya rabuwa da sabuntawar kayan aiki ba. Kowane taron feshin zafi na duniya zai sami rahotanni game da sabbin kayan aiki. Saboda ƙarancin zafinsa da ƙirarsa mai saurin sauri, bindigar feshin K2 don feshin GTV HVOF na iya fesa suturar ƙarfe irin su Cu coatings, kuma abun ciki na iskar oxygen na rufin shine kawai 0.04%, wanda yayi daidai da feshin sanyi. Yin amfani da tsarin feshin HVOF mai ƙarfi mai ƙarfi, matsi na ɗakin konewa zai iya kaiwa 1 ~ 3MPa, kuma zafin wutar yana da ƙarancin zafin jiki da saurin gudu, yana fesa 316L bakin karfe foda, ƙimar ajiya na iya isa 90%.

Na'urorin injin injin injin gas sun fara amfani da abubuwan da aka fesa da ruwan zafi na plasma, kamar YSZ, LazZrzO, SmzZrzO, GdzZr20 tsarin sutura, waɗanda ake amfani da su sosai a ƙasashen waje kuma a halin yanzu sanannen filin bincike ne a China.
