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

⑵ Chemical kupisa kurapwa:
Zvinoreva kune kemikari element maatomu, nekugona kwekupararira kweatomu pakupisa kwepamusoro, iyo ichipinda pamusoro pechishandiso chebasa, kushandura kemikari uye chimiro chechikamu chepamusoro cheiyo workpiece, kuitira kuti uwane iyo yepamusoro simbi ine zvakanangana nezvinodiwa zvesangano uye kuita 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. Inoitawo kuti yakaderera kabhoni simbi workpiece nepamusoro kabhoni simbi pamusoro layer, uye ipapo pashure quenching uye yakaderera tembiricha tempering, kuitira kuti pamusoro pemvura workpiece ane yakakwirira kuoma uye kupfeka kuramba, uye chikamu chepakati workpiece vachiri kuramba kuoma uye plasticity yakaderera kabhoni simbi.
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 pamusoro pemvura yesimbi alloying, kuitira kuti iite workpiece yepamusoro ine imwe alloy simbi, inokosha simbi unhu, akadai kupisa kuramba, kupfeka kuramba, oxidation kuramba, ngura kuramba, etc .. Inowanzoshandiswa mukugadzirwa aluminizing, chromizing, boronizing, nesilicon uye zvichingodaro.
