Waa maxay ujeedada daaweynta kulaylka dusha sare

①Hagaajinta iska caabbinta xidhashada ee qaybaha Lakabka sare ee kaarboon martensitic ee adag waxaa lagu heli karaa carburizing iyo deminta qaybaha birta; Kala firdhinta lakabka sare ee adag ee nitride alloy waxaa lagu heli karaa habka nitriding ee qaybaha birta daawaha. Engegnaanta dusha sare ee qaybaha birta ee ay heleen labadan hab waxay gaari karaan HRC58～62 iyo HV800～1200 siday u kala horreeyaan. Siyaabo kale ayaa ah in la sameeyo filim-dhimista iyo ka-hortagga filimka dusha sare ee birta si loo hagaajiyo xaaladaha isku-dhafka, taas oo sidoo kale hagaajin karta caabbinta xirashada. Tusaale ahaan, dusha daawaynta uumiga wuxuu soo saaraa filimka ferroferric oxide kaas oo leh saamaynta anti-adhesion; vulcanization dusha sare wuxuu helayaa filim ferrous sulfide ah, kaas oo yeelan kara labadaba saamaynta ka-hortagga xirashada iyo ka-hortagga adhesionka. Habka isku-duwidda qaybaha kala duwan ee la sameeyay sannadihii la soo dhaafay, sida oxygen-nitriding, sulfur-nitrogen co-infiltration, carbon-nitrogen-sulfur-oxy-boron shan-element is-dhexgalka, iwm, waxay isku mar samayn kartaa heer sare. -lakabka faafinta adkaanta iyo ka-hortagga-ku-dhejinta ama filimka-ka-hortagga, si wax ku ool ah u wanaajinaya caabbinta xirashada qaybaha, gaar ahaan caabbinta adhesion.

Ku

②Hagaajinta xoogga daalka ee qaybaha. Carburizing, nitriding, nitriding jilicsan iyo hababka carbonitriding dhamaantood waxay ka dhigi karaan dusha sare ee qaybaha birta inay xoojiyaan marka la samaynayo cadaadiska haraaga ee dusha sare ee qaybaha, si wax ku ool ah u wanaajiya xoogga daalka ee qaybaha.

Ku

③Hagaajinta iska caabinta daxalka iyo iska caabinta oksaydhka heerkulka sare ee qaybaha. Tusaale ahaan, nitriding waxay wanaajin kartaa iska caabinta daxalka atmospheric ee qaybaha; ka dib markii aluminium, chromizing, iyo qaybaha birta siliconizing, waxay ka falcelin doontaa oksijiinta ama warbaahinta daxalka si ay u sameeyaan cufan iyo xasilloon oo Al2O3, Cr2O3 , SiO2 filimka ilaalinta, hagaajinta iska caabinta daxalka iyo iska caabinta oksaydhka heerkulka sare.

Ku

Guud ahaan, qaybaha birta ahi waxay noqonayaan curyaan marka la adkeeyo. Marka habka qallafsanaanta dusha sare loo isticmaalo si loo kordhiyo qallafsanaanta dusha sare, xudunta ayaa weli lagu sii hayn karaa xaalad adag oo wanaagsan, sidaas darteed waxay si fiican u xallin kartaa iskahorimaadka u dhexeeya adkaynta qaybaha birta iyo adkaanteeda marka loo eego habka qallafsanaanta isku-dhafka ah ee qaybaha. Daawaynta kulaylka kiimikadu waxay beddeshaa isku dhafka kiimikaad iyo qaab dhismeedka dusha sare ee qaybaha birta isku mar, markaa way ka waxtar badan tahay hababka adkaynta dusha sare sida soo noqnoqoshada koronto ee sare iyo dhexdhexaadka ah iyo deminta ololka. Haddii qaybta dhexgalka loo doorto si habboon, lakabka dusha sare ee ku habboon shuruudaha waxqabadka kala duwan ee qaybta ayaa la heli karaa.
