#### Kenyelletso ea Sehlahisoa
INCONEL 625 thermal spray wire ke sesebelisoa se sebetsang hantle se etselitsoeng lisebelisoa tsa ho fafatsa ka arc. E tsebahala ka ho hanyetsa ha eona ka mokhoa o ikhethang ho bola, oxidation le mocheso o phahameng, terata ena e sebelisoa haholo liindastering tse fapaneng ho matlafatsa ts'ebetso le nako ea bophelo ea likarolo tsa bohlokoa. Mehaho ea eona e ikhethang e etsa hore e be e loketseng bakeng sa litlolo tse sireletsang, ho tsosolosa holim'a metsi, le lisebelisoa tse sa senyeheng. INCONEL 625 e netefatsa ts'ebetso e holimo le maemong a thata ka ho fetesisa, e e etsa khetho e tšepahalang bakeng sa ts'ebeliso ea liindasteri, sebaka sa sefofane le sa metsing.

#### Tokiso ea Sebaka
Tokiso e nepahetseng ea bokaholimo e bohlokoa bakeng sa ho fumana liphetho tse nepahetseng ka terata e futhumatsang ea INCONEL 625. Bokaholimo bo lokelang ho koaheloa bo lokela ho hloekisoa hantle ho tlosa litšila tse kang mafura, oli, litšila le li-oxide. Grit blasting e nang le aluminium oxide kapa silicon carbide e khothaletsoa ho fihlela boima bo holimo ba 75-125 microns. Ho etsa bonnete ba hore sebaka se hloekile le se thatafalitsoeng se matlafatsa ho khomarela ha setlolo se chesang se futhumatsang, se lebisang ts'ebetsong e ntlafetseng le ho phela nako e telele.
