W6Mo5Cr4V2(M2) birta duuban ee kulul

M2 waa molybdenum taxane bir xawaare sare leh, waxay leedahay faa'iidooyin la'aanta carbide yar iyo adkaanta sare. Way fududahay in la kululeeyo, waa in si adag loo xakameeyo heerkulka kuleylka kuleylka, ilaalinta adag ee daaweynta kulaylka. Sababtoo ah adayggeeda iyo daalkeeda, loo isticmaalo soo saarista jarista aad u adag in la gooyo qalabka qalabka. M2 birta xawaaraha sare leh oo leh jihada carbide waa ka weyn tahay, markaa ilaalinta adag ee daaweynta kulaylku waxay ku habboon tahay gariirka caaryada iyo culeysyada naxdinta leh.

• Qalabka M2 ee birta adag

Birta M2 oo leh adkeysi aad u sarreeya waana in lagu adkeeyaa iyadoo lagu qaboojinayo hawada weli jirta. Isticmaalka qubeyska milixda ah ama foornada jawiga la xakameeyey ayaa la jecel yahay si loo yareeyo decarburization, iyo haddii aan la heli karin, baakad adag oo ku jirta kookaha la isticmaalay ayaa la soo jeediyay.
