Cobalt's Crucible: M35 vs M42 Metallurgical Showdown
Ntoa pakeng tsa M35 (HSSE) le M42 (HSS-Co8) cobalt drills e itšetlehile ka metsoako ea bona ea lik'hemik'hale le ho mamella mocheso:
M35 (5% Cobalt): Alloy e leka-lekaneng e fanang ka molemo oa 8-10% oa ho tiea ho feta M42, e loketseng bakeng sa ho khaola ho senyehileng le li-setups tse tloaelehileng tsa vibrate. E tšeloa mocheso ho fihlela HRC 64-66, e mamella mocheso ho fihla ho 600°C.
M42 (8% Cobalt): Tlhōrō ea boima bo bofubelu, e boloka HRC 65+ ho 650 ° C. Ka vanadium e ekelitsoeng bakeng sa ho hanyetsa ho roala, e sebetsa hantle ho cheka ho tsoelang pele ka lebelo le phahameng empa e hloka ho ts'oaroa ka hloko ho thibela brittleness.
Liteko tsa batho ba boraro ba abrasion li senola M42 ea 30% ea nako e telele ea lisebelisoa tsa lisebelisoa tsa 304 tšepe e sa hloekang ka 30 m / min, ha M35 e feta ka 15% ka ho hanyetsa tšusumetso nakong ea mekoloko ea ho phunya peck.
