### Incazelo Yomkhiqizo yeINCONEL 625 Thermal Spray Wireokwe-Arc Spraying
#### Isingeniso Somkhiqizo
I-INCONEL 625 i-thermal spray wire iyinto esebenza kahle kakhulu eyenzelwe izinhlelo zokusebenza zokufafaza nge-arc. Le ntambo eyaziwa kakhulu ngokumelana nokugqwala, i-oxidation, kanye namazinga okushisa aphezulu, isetshenziswa kakhulu ezimbonini ezahlukahlukene ukuthuthukisa ukuqina nempilo yezingxenye ezibalulekile. Izakhiwo zayo eziyingqayizivele ziyenza ifaneleke ukumbozwa ngokuzivikela, ukubuyisela indawo engaphezulu, nezinhlelo zokusebenza ezingagugi. I-INCONEL 625 iqinisekisa ukusebenza okuseqophelweni eliphezulu ngisho nasezimweni ezinzima kakhulu, ikwenze kube ukukhetha okuthembekile kwezimboni, i-aerospace, nezinhlelo zokusebenza zasolwandle.
#### Ukulungiswa kwendawo
Ukulungiswa kahle kwendawo kubalulekile ukuze uthole imiphumela emihle nge-INCONEL 625 yocingo lwesifutho esishisayo. Ingaphezulu elizogcotshwa kufanele lihlanzwe kahle ukuze kukhishwe noma yikuphi ukungcola okunjengamafutha, uwoyela, ukungcola, nama-oxide. Ukuqhunyiswa kwegrit nge-aluminium oxide noma i-silicon carbide kuyanconywa ukuze kuzuzwe ubulukhuni obungaphezulu kwama-microns angu-75-125. Ukuqinisekisa indawo ehlanzekile futhi eqinile kuthuthukisa ukunamathela kwesifutho esishisayo, okuholela ekusebenzeni okuthuthukisiwe nokuphila isikhathi eside.
