Mathata a Tloaelehileng le Tlhahlobo ea Sesosa sa Khatello ea Cemented Carbide

Carbide e entsoeng ka samente ke motsoako oa alloy o entsoeng ka motsoako o thata oa tšepe ea refractory le tšepe e kopanyang ka mokhoa oa phofo oa metallurgy.E na le thepa ea boima bo phahameng, ho hanyetsa ho apara, matla le ho tiea.Ka lebaka la thepa ea eona e ikhethang, hangata e sebelisoa ho etsa lisebelisoa tsa ho phunya majoe, lisebelisoa tsa merafo, lisebelisoa tsa ho phunya, lisebelisoa tsa ho lekanya joalo-joalo.E sebelisoa haholo ho petroleum le khase ea tlhaho, indasteri ea lik'hemik'hale, mechine ea kaho, taolo ea metsi le masimo a mang.Carbide e entsoeng ka samente ke thepa e hatelitsoeng ke metallurgy ea phofo.Kajeno, Chuangrui Xiaobian o tla u tsebisa mathata a 'maloa a maholo ao hangata re kopanang le ona ts'ebetsong ea khatiso, mme a hlahlobe mabaka ka bokhutšoanyane.

1. Ts'ila e atileng haholo ea ho hatella ka har'a semente sa carbide ke delamination

E hlaha haufi le moeli oa thibelo ea khatello, ka lehlakoreng le itseng ho ea holim'a khatello, ho etsa sebopeho se makhethe se bitsoa delamination.Boholo ba layering bo qala likhutlong ebe bo fetela ho compact.Lebaka la delamination ea compact ke khatello ea kelello e ka hare kapa tsitsipano ea elastic ka har'a compact.Ka mohlala, motsoako oa cobalt oa motsoako o batla o le tlaase, boima ba carbide bo phahame, phofo kapa karoloana e ntle, mochine oa ho bōpa o monyenyane haholo kapa kabo ha e tšoane, motsoako o kolobile haholo kapa o omme haholo; khatello ea khatello e kholo haholo, boima ba yuniti bo boholo haholo, 'me matla a ho hatella a phahame haholo.Sebopeho sa li-block se rarahane, sebopeho sa hlobo se fokola haholo, 'me sebaka sa tafole ha se lekane, se ka bakang delamination.

Ka hona, ho ntlafatsa matla a compact le ho fokotsa khatello ea ka hare le mololi oa mokokotlo oa compact ke mokhoa o sebetsang oa ho rarolla delamination.

2. Ketsahalo ea uncompressed (likaroloana tse bontšitsoeng) e tla boela e etsahale nakong ea ts'ebetso ea ho hatella ea carbide e entsoeng ka samente.

Hobane boholo ba li-pores tsa compact li kholo haholo, li ke ke tsa nyamela ka ho feletseng nakong ea sintering, e leng se etsang hore ho be le li-pores tse khethehileng tse setseng 'meleng oa sintered.Li-pellets li thata haholo, li-pellets li boima haholo, 'me thepa e hlephileng e kholo haholo;li-pellets tse hlephileng li ajoa ka mokhoa o sa tšoaneng ka sekoting, 'me boima ba yuniti bo tlaase.e ka etsa hore motho a se ke a hatella.
