⑴ Kudzima kwepamusoro:
Iri pamusoro pesimbi kuburikidza nekupisa nekukurumidza kusvika kune yakakosha tembiricha iri pamusoro, asi kupisa kwave kusina nguva yekupararira kusvika pakati kusati kwakurumidza kutonhora, kuitira kuti nzvimbo yepamusoro inogona kudzimwa mune martensitic tishu, uye musimboti hauna kuitika. phase shanduko, iyo inoona kuoma kwepamusoro uye musimboti usingachinji.Inokodzera pakati kabhoni simbi.

⑵ Chemical kupisa kurapwa:
Zvinoreva kune kemikari element maatomu, nekugona kwekupararira kweatomu pakupisa kwepamusoro, iyo muchikamu chepamusoro chebasa rekushanda, kushandura chimiro chemakemikari uye chimiro chepamusoro-soro chebasa rekushanda, kuitira kuti uwane chikamu chepamusoro chesimbi. nezvinodiwa zvakananga zvesangano uye kushanda kwemaitiro ekupisa kupisa.Zvinoenderana nemhando dzekupinza zvinhu, makemikari kupisa kurapwa anogona kukamurwa kuita carburizing, nitriding, cyanidation uye simbi infiltration mutemo.
Carburizing: Carburizing ndiyo nzira iyo kabhoni maatomu anopinda nepamusoro pesimbi.Iko zvakare kugadzira iyo yakaderera kabhoni simbi workpiece ine yakakwira kabhoni simbi pamusoro peturu, uyezve mushure mekudzima uye yakaderera tembiricha kudziya, kuitira kuti iyo yekumusoro dhizaini yeworkpiece ine yakanyanya kuomarara uye kupfeka kuramba, uye chikamu chepakati cheworkpiece chichiri kuchengetedza kuoma uye purasitiki yesimbi yakaderera kabhoni.
Nitriding, kana nitriding, inzira iyo iyo pamusoro pesimbi inopinda maatomu enitrogen.Icho chinangwa ndechekuvandudza kuomarara uye kupfeka kuramba kweiyo yepamusoro layer uye kuvandudza kuneta kwesimba uye corrosion resistance.Parizvino, gasi nitriding nzira inoshandiswa mukugadzira.
Cyanidation, inozivikanwawo secarbonitriding, ndiko kupinza panguva imwe chete kwekabhoni nenitrogen maatomu musimbi.Inogadzira pamusoro pesimbi carburizing uye nitriding maitiro.
Metal penetration: kunoreva kupinda kwemaatomu esimbi muchikamu chepamusoro chesimbi.Iko kugadzira iyo yepamusoro yesimbi yesimbi alloying, kuitira kuti iite workpiece yepamusoro ine imwe alloy simbi, yakakosha simbi maitiro, akadai sekudzivirira kupisa, kupfeka kusagadzikana, oxidation resistance, corrosion resistance, etc .. Inowanzoshandiswa pakugadzirwa kwe aluminizing, chromizing, boronizing, silicon uye zvichingodaro.
