Li-powders tsa WC-CrC-Ni tse nang le khanyetso ea ho apara
Tlhaloso
Mohala oa sehlahisoa sa phofo oa WC-CrC-Ni ke letoto la li-powders tse kopantsoeng le tse sintered tse fanang ka mokhoa o mong ho feta chromium plating e thata.Liphofshoana tsena li etselitsoe ho sebelisoa libakeng tse tlase tsa asiti/alkali mochesong o fihlang ho 200 ℃, 'me li fana ka anti-oxidation e ntle haholo le ho hanyetsa mocheso mocheso o ka holimo ho 750 ℃.
E 'ngoe ea lihlahisoa tsa bohlokoa moleng ona ke KF-66, e nang le 23% CrC le 7% Ni, e nang le boholo ba likaroloana tsa 15-45 μm le 10-38 μm.Sehlahisoa sena se na le mekhoa e mengata haholo 'me se ka sebelisoa e le phetisetso ea chromium e thata lits'ebetsong tse fapaneng.E sebetsa haholo maemong a tlase a acid / alkali mocheso o fihlang ho 200 ℃.Ho phaella moo, KF-66 e fana ka khanyetso e babatsehang ho oxidation le ho apara ka mocheso ho fihlela ho 750 ℃.
Sehlahisoa se seng sa bohlokoa moleng oa phofo oa WC-CrC-Ni ke KF-66, e nang le 43% CrC le 14% Ni, e nang le boholo bo lekanang le boholo ba 15-45 μm le 10-38 μm.Joalo ka KF-66, phofo ena ke khetho e ntle ka ho fetesisa ea chromium plating, 'me e sebetsa haholo maemong a tlase a acid / alkali mocheso ho fihla ho 200 ℃.
Ntle le ts'ebetso ea bona e phahameng ea anti-oxidation le khanyetso ea ho roala, li-powders tsa WC-CrC-Ni li fana ka melemo e meng e mengata ho feta plating e thata ea chromium.Bakeng sa e 'ngoe, li bonolo haholo ho li sebelisa' me li hloka lisebelisoa tse fokolang tse khethehileng.Li boetse li na le botsoalle haholoanyane tikolohong, kaha ha li hlahise li-byproducts tse chefo joalo ka plating ea chromium e thata.
Ka kakaretso, mohala oa sehlahisoa sa phofo oa WC-CrC-Ni o fana ka mokhoa o mong o sebetsang hantle ho feta oa setso sa chromium plating.Li-powders tsena li fana ka li-anti-oxidation tse phahameng le ho roala ho hanyetsa mocheso o phahameng, ho etsa hore e be tse loketseng bakeng sa mefuta e sa tšoaneng ea lisebelisoa tsa indasteri.Hore na o batla phetoho bakeng sa plating e thata ea chromium kapa o hloka feela phofo e sebetsang hantle bakeng sa ho sebelisoa maemong a thata, mohala oa sehlahisoa oa WC-CrC-Ni ke khetho e ntle haholo.
