Iimpawu zokusebenza ze emoyeni eziko emoyeni

Isithando somlilo se-vacuum yitekhnoloji ebanzi edibanisa itekhnoloji ye-vacuum kunye nonyango lobushushu. Kuthetha ukuba yonke kunye nenxalenye yenkqubo yonyango lokushisa iqhutyelwa kwisimo se-vacuum. ilizwe lam lahlula ivacuum ibeyivacuum esezantsi, ephakathi, ephezulu kunye nephezulu kakhulu. Okwangoku, i-vacuum esebenzayo ye-vacuum eninzi ye-atmosphere yi-1.33 ~ 1.33 × 10ˉ3Pa.

Isithando somlilo sevacuum emoyeni siphantse saziqonda zonke iinkqubo zokunyanga ubushushu, ezinje ngokucima, ukufunxa, ukufudumeza, ukungcwatywa kunye ne-nitriding. Kwinkqubo yokucima, inokuqonda ukucinywa kwegesi, ukucima ioli, ukucima i-nitrate, ukucima amanzi, njl., kunye ne-vacuum brazing. , I-Sintering, unyango olungaphezulu, njl.

Isithando somlilo sinomgangatho ophezulu we-thermal, inokuqonda ukufudumeza ngokukhawuleza kunye nokupholisa, ayinakufezekisa i-oxidation, akukho decarburization, akukho carburization, inokususa iitshiphusi ze-phosphorus kumphezulu we-workpiece, kwaye inemisebenzi yokunciphisa kunye nokukhupha, ukuze kufezekiswe. isiphumo sokucocwa okuqaqambileyo komphezulu. Ngokuqhelekileyo, i-workpiece ecutshungulweyo ifudunyezwa ngokucothayo kwi-vacuum atmosphere eziko, umahluko wobushushu bangaphakathi umncinci, uxinzelelo lwe-thermal luncinci, kwaye ukuguqulwa kuncinci.

Kwangaxeshanye, izinga elifanelekileyo leemveliso zesithando somlilo wevacuum iphezulu. Inokunciphisa iindleko kwaye ibe nefuthe lokukhupha igesi, ngaloo ndlela iphucula ukusebenza komatshini kunye nobomi benkonzo yomsebenzi. Indawo yokusebenza ilungile, umsebenzi ukhuselekile, kwaye akukho lungcoliso nongcoliseko. Akukho mngcipheko we-hydrogen embrittlement ye-workpiece ecutshungulwayo, kwaye umphezulu we-hydrogen embrittlement uthintelwe kwi-titanium kunye ne-refractory metal shells, kunye nokuzinza kunye nokuphindaphinda kwenkqubo yesithando somlilo kulungile. Ngolu chungechunge lweenzuzo, uphuhliso lwezixhobo zesithando somlilo kunye neteknoloji ihlawulwe ngakumbi nangakumbi kwaye isetyenziswa ngokubanzi.
