Dareemka cadaadiska sare ee YN52S00027P1 wuxuu ku habboon yahay SK200-6 qodista Shengang

◆ Walxaha loo isticmaalo tuubooyinka cadaadiska aadka u sarreeya, daawaynta kulaylka iyo adkaynta dusha sare ayaa inta badan loo isticmaalaa si loo hagaajiyo iska caabbinta extrusion iyo caabbinta nabaadguurka.

1, daawaynta kulaylka faakuumka

Daawaynta kulaylka faakuumka waxa loola jeedaa habka daawaynta kulaylka kaas oo qaybta shaqada la geliyo faakuum.Daawaynta kulaylka faakuumku ma soo saarto oksaydhka, decarburization iyo daxalka kale inta lagu jiro kuleylka, laakiin sidoo kale waxay leedahay shaqada nadiifinta dusha sare, hoos u dhigista iyo hoos u dhigista.Hydrogen, nitrogen iyo oxygen ay nuugaan walxaha inta lagu jiro dhalaalidda waxaa laga saari karaa vacuum, tayada iyo waxqabadka maaddada waa la hagaajin karaa.Tusaale ahaan, ka dib daawaynta kulaylka faakuumka irbadda cadaadiska aadka u sarreeya ee ka samaysan W18Cr4V, saamaynta badheedhka irbadda si wax ku ool ah ayaa loo kordhiyaa, isla mar ahaantaana, sifooyinka farsamada iyo nolosha adeegga ayaa la hagaajiyaa.

2. Daaweynta xoojinta dusha sare

Si loo hagaajiyo waxqabadka qaybaha, marka lagu daro beddelka walxaha, habab daaweyn oo xoojin ah oo dusha sare ah ayaa la qaataa.Sida deminta dusha sare (kuleylka ololka, kuleylinta sare iyo dhexdhexaadka ah ee kululaynta dusha sare, la xiriir deminta kuleylka korantada, deminta dusha sare ee kuleylka elektrolytka, deminta dusha sare ee laydhka elektarooniga ah kuleylka kuleylka, iwm.), carburizing, nitriding, cyanid, boronizing (hab TD). xoojinta laysarka, kaydinta uumiga kiimikada (habka CVD), kaydinta uumiga jirka (Habka PVD), kaydinta uumiga kiimikada balaasmaha (habka PCVD) buufinta balaasmaha, iwm.

Dhigista uumiga jirka (habka PVD)

Xayawaanka, hababka jireed sida uumiga, ion plating iyo sputtering ayaa loo isticmaalaa si loo soo saaro ion biraha.Iions biraha kuwan waxaa lagu shubaa on dusha of workpiece si ay u sameeyaan daahan bir ah, ama falcelin la reactor si ay u sameeyaan daahan kaabsal.Habka daawayntan waxa loo yaqaan kaydka uumiga jirka, ama PVD gaaban.Habkani wuxuu leeyahay faa'iidooyinka heerkulka dhigaalka hooseeya, 400 ~ 600 ℃ heerkulka daaweynta, qallafsanaanta yaryar iyo saameyn yar oo ku saabsan qaabka matrixka iyo sifooyinka qaybaha.Lakabka TiN ayaa lagu shubay waalka irbadda ee ka samaysan W18Cr4V habka PVD.Lakabka TiN waxa uu leeyahay qallafsanaan aad u sarreeya (2500～3000HV) iyo iska caabbinta xidhashada sare, taas oo wanaajisa iska caabbinta daxalka ee waalka, kuma daxaloobayn hydrochloric acid, sulfuric acid iyo nitric acid, oo waxay hayn kartaa oog dhalaalaysa.Ka dib daaweynta PVD, dahaarka ayaa leh saxsanaan wanaagsan.Waa la dami karaa oo la simayn karaa, oo qallafsanaantiisuna waa Ra0.8µm, kaas oo gaadhi kara 0.01µm ka dib dhalaalidda.
