Umuvuduko ukabije wumuvuduko YN52S00027P1 ukwiranye na SK200-6 icukura Shengang

◆ Kubikoresho bikoreshwa mumashanyarazi arenze urugero, kuvura ubushyuhe no gukomera hejuru bikoreshwa mugutezimbere kwangiza no kurwanya isuri.

1, kuvura ubushyuhe

Kuvura ubushyuhe bwa Vacuum bivuga uburyo bwo gutunganya ubushyuhe aho igihangano gishyirwa mu cyuho. Kuvura ubushyuhe bwa Vacuum ntabwo bitanga okiside, decarburisation nizindi ruswa mugihe cyo gushyushya, ariko kandi ifite umurimo wo kweza hejuru, kwangirika no kwangirika. Hydrogen, azote na ogisijeni byinjijwe nibikoresho mugihe cyo gushonga birashobora gukurwaho mu cyuho, kandi ubwiza n’imikorere yibikoresho birashobora kunozwa. Kurugero, nyuma yo kuvura ubushyuhe bwa vacuum ya ultra-high pressure inshinge ya valve ikozwe muri W18Cr4V, ingaruka nkana za valve yinshinge ziyongera neza, kandi mugihe kimwe, imiterere yubukanishi nubuzima bwa serivisi biratera imbere.

2. Ubuvuzi bushimangira ubuvuzi

Kugirango tunoze imikorere yibice, usibye guhindura ibikoresho, hakoreshwa ubundi buryo bwo gushimangira uburyo bwo kuvura. Nkokuzimya hejuru (gushyushya flame, kuzimya hejuru no hagati yubushyuhe bwo hejuru kuzimya, guhuza umuriro wo gushyushya amashanyarazi, kuzimya amashanyarazi ya electrolyte, kuzimya hejuru ya laser electron beam, nibindi), carburizing, nitriding, cyanide, boronizing (uburyo bwa TD), gukomera kwa lazeri, kubika imyuka ya chimique (uburyo bwa CVD), kubitsa imyuka yumubiri (uburyo bwa PVD), kubika imiti ya plasma yamashanyarazi (uburyo bwa PCVD) gutera plasma, nibindi.

Imyuka yumubiri ifatika (uburyo bwa PVD)

Mu cyuho, uburyo bwumubiri nko guhumeka, gusiga ion no gusohora bikoreshwa mu gukora ioni. Iyoni zicyuma zishyirwa hejuru yakazi kugirango zikore icyuma, cyangwa zigakorwa na reaction kugirango zibe igifuniko. Ubu buryo bwo kuvura bwitwa imyuka yumubiri, cyangwa PVD mugihe gito. Ubu buryo bufite ibyiza byubushyuhe buke, 400 ~ 600 temperature ubushyuhe bwo kuvura, guhindura ibintu bito no kugira ingaruka nke kumiterere ya matrix nimiterere yibice. Igice cya TiN cyashyizwe kuri valve y'urushinge ikozwe muri W18Cr4V hakoreshejwe uburyo bwa PVD. Igice cya TiN gifite ubukana buhebuje (2500 ～ 3000HV) hamwe no kwihanganira kwambara cyane, biteza imbere kwangirika kwa valve, ntabwo byangirika muri acide hydrochloric acide, acide sulfurike na aside nitric, kandi birashobora kugumana ubuso bwiza. Nyuma yo kuvura PVD, igifuniko gifite ukuri neza. Irashobora kuba hasi kandi igasukurwa, kandi hejuru yubuso bwayo ni Ra0.8µm, ishobora kugera kuri 0.01µm nyuma yo gusya.
