W6Mo5Cr4V2(M2) litšepe tse pota-potiloeng tse chesang

M2 ke molybdenum letoto la tšepe e phahameng ka lebelo le phahameng, e na le melemo ea ho inhomogeneity e nyane ea carbide le boima bo phahameng. Ho bonolo ho overheating, lokela ho tieo laola quenching futhumatsang mocheso, le ho feta ka thata-thata tšireletso bakeng sa mocheso kalafo. Ka lebaka la ho thatafala ha eona le ho apara, e sebelisoang ha ho etsoa ho itšeha ho thata haholoanyane ho seha lisebelisoa tsa lisebelisoa. M2 tšepe e lebelo le phahameng e nang le sebopeho sa carbide e kholoanyane, ka hona ts'ireletso e matla haholoanyane bakeng sa kalafo ea mocheso e loketse ho sisinyeha ha hlobo le meroalo e tšosang.
