Lisebelisoa tse fapaneng, mocheso o fapaneng oa ho tima le mocheso o futhumatsang le tsona li fapane. Mohlala, ho thatafala ha 3Cr2W8V tšepe aluminium-magnesium alloy die-cast hlobo ke ka kakaretso 42 ～ 48HRC, 'me mocheso oa eona o futhumatsang ka kakaretso o khethoa lipakeng tsa 560 ～ 620 ℃, empa haeba ho sebelisoa mocheso o phahameng, mocheso o futhumetseng o phahame joalo ka 670 ℃. Thata kamora ho tima ka 1150 ° C le tempering ho 650 ° C ke 45HRC; ha boima ka mor'a ho tima ka 1050 ° C le tempering ho 650 ° C ke 35HRC. Ho thatafala ha H13 tšepe aluminium-magnesium motsoako shoa-lahla hlobo e hlokahala hore e be 44 ～ 50HRC. Tlhoro ea bobeli e thatafatsang ea tšepe ea H13 e hlaha ha e futhumala ho 500 ℃, empa boholo ba tlhoro bo amana le mocheso o tima. Mocheso o futhumatsang ka kakaretso ke 560 ～ 620 ℃. Bohale bo lokela ho etsoa makhetlo a 2 ho isa ho a mararo. Mocheso oa tempering ea pele o ka ba tlase. Ka mor'a hore tempering pele, lekanya boleng thatafala. Ha tlhokahalo ea ho thatafala e fihlile, mocheso oa tempering o lokela ho theoloa ke 3, 20 ℃ ho qoba The thatafala ea fokotseha. Haeba thatafala e phahameng haholo, fetola thempereichara tempering ka nepo ho kopana le tlhokahalo ea thatafala ho latela thatafala phahameng. Bohale ba boraro ke ho ntlafatsa ho thatafala, mocheso o futhumetseng o lokela ho ba holimo ho feta oa bobeli

Mocheso oa bobeli oa tempering o tlase ho 30 ～ 50.. Nako ea ho halefa le ho ts'oara e lokela ho lekana ho felisa khatello ea maikutlo e tlisoang ke ho tima le ho fokotsa sebopeho sa mapetso a hlobo. Nako ea ho ts'oara e ngoe le e ngoe ke 2h, 'me nako ea ho ts'oara hlobo e kholo e atolositsoe ka nepo. Ka lebaka la khatello e phahameng ea mocheso le khatello ea "microstructure" ea "die-casting" e shoang kamora ho tima, lefu leo ​​hangata le halefisoa hang kamora ho phola ho 150-200 ° C.

Holim 'a matlafatsa kalafo thulaganyou e aluminium-magnesium motsoako shoa-lahla hlobo

Kamora ho tima le ho halefa, bokaholimo ba bokahare ba aluminium-magnesium alloy die-cast ha e phahameng haholo. E le hore ho fumana thatafala phahameng le apara ho hanyetsa holim 'a hlobo e, ha karolo ea mantlha e ntse e boloka matla a lekaneng le toughness, le ho ntlafatsa tshebetso-ba khahlanong le ho khomarela ea aluminium-magnesium motsoako shoa-lahla hlobo, holim nitriding kapa nitriding ka etsoa ka hlobo ena. Kalafo ea Carburizing.

4.1 Phekolo ea nitriding

Nitriding ke ts'ebetso ea kalafo ea mocheso oa nitriding ka holim'a tšepe ho eketsa mohopolo oa naetrojene karolong e kaholimo ea lera. Morero oa nitriding ke ho fokotsa ho fetoha ha likarolo tsa hlobo, ho ntlafatsa bokhabane ba bokaholimo, ho roala ho hanyetsa, matla a mokhathala le ho hanela ho ts'oaroa ha hlobo ea aluminium-magnesium alloy le ho ntlafatsa ho hanyetsa bohale le ho nolofatsa. Notch nahanela. Nitriding e tiileng, nitriding ea metsi le nitriding ea khase ke mekhoa e tloaelehileng ea nitriding. Mahlale a macha a kang ion nitriding, vacuum nitriding, electrolytic nitriding le high-frequency nitriding a ka khutsufatsa potoloho ea nitriding, a fumana boleng bo phahameng ba nitriding le ho ntlafatsa ts'ebetso ea moruo ea likhoebo, ka hona li sebelisoa haholo tlhahiso.

4.2 Nitrocarburizing

Nitrocarburizing ke ammonia hammoho le lino tse tahang (methanol, ethanol) le mecha ea phatlalatso e kenang e kang urea, formy glue le triethanol glue. Ts'ebetso ea ho bola ha mocheso e etsahala mochesong o itseng ho hlahisa liathomo tse sebetsang tsa naetrojene le khabone, tse bolailoeng ke lits'epe tse kopantsoeng ke aluminium-magnesium. Kamora hore hlobo e kenngoe kahare, e a arohana ebe e kenella ka holim'a lera la hlobo ho fumana lera la nitrocarburizing le nang le naetrojene, e le hore hlobo e fumane thatafalo e phahameng ea bokaholimo, ho hanyetsa mokhathala, ho itšireletsa le ho hanyetsa ts'enyeho. Mekhoa ea nitrocarburizing e kenyelletsa mekhoa ea mokelikeli le khase, mme mekhoa e mengata e sebelisoang tlhahiso ke khase ea nitrocarburizing. The H13 steel aluminium alloy die-casting hlobo e futhumetse ka mekhahlelo e 'meli ea kalafo ea pele ho mocheso ho 550 ℃ × 40min le 850 ℃ × 40min ka seboping se nang le mocheso o phahameng oa letsoai, e tima ka 1030 ℃, e haelloang ke 600 ℃, ebe e fuoa ho phekola kalafo ea mocheso oa khase ea nitrocarburizing ho 580 ℃. Thatafala e kaholimo ho 900HV, popeho thatafala ke 46 ~ 48HRC, qhoaele hanyetsa, mokhathala ho hanyetsa, le ts'enyeho ho hanyetsa hlobo li ntlafalitsoe haholo, 'me ha ho mamarello, ebola, mengoapo le ts'enyeho, e leng se atlehang ho ntlafatsa bophelo ba hlobo.
