Precision piston tsvimbo parizvino inoshandiswa mumaindasitiri mazhinji kune chigadzirwa, imhaka yekuti piston tsvimbo inoshandiswa zvakanyanya, saka vanhu vepiston tsvimbo yekugadzira zvinhu kusarudzwa kunowedzerawo kutarisisa kusarudzwa kwezvinhu zvakasiyana zvekugadzira, zvino kugadzirwa kwayo precision piston rod performance uye hunhu hwakasiyanawo.
45# simbi isimbi yekabhoni, yakanaka kutonhora uye inopisa kugadzirisa kushanda, mechanical properties, yakakwirira simba.45# simbi mu quenching pasina tempering pamberi, kuoma kukuru kupfuura HRC55 vanokwanisa, uye pashure kupisa kurapwa, uye ipapo quenching anogona kusvika HRC42-46, kuitira kuti chaiyo piston tsvimbo ane yakanaka michini zvinhu uye kuoma.
40Cr isimbi yepakati carbon tempered, mushure mekurapa kwakakodzera kupisa, unogona kuwana kuoma kwakanaka, plastiki.Uye inogona kuve neyakanaka yakazara mekiniki zvivakwa mushure mekupisa kurapwa, yakanaka yakaderera tembiricha kukanganisa kuoma.Mukuwedzera, iyi simbi inokodzera cyanidation uye yakakwirira frequency quenching kurapwa mukuwedzera kune tempering kurapwa.
GCr15 simbi imhando yealloy yemukati yakaderera yakakwira kabhoni chromium ine simbi, ine yakanyanya kuoma, mushure mekupisa kurapwa kunogona kuwanikwa mushure mekuoma kwepamusoro uye kwakafanana.Uye kana ichinge yadzimwa plus yakaderera tembiricha tembiricha kurapwa, inogona kuva yakakwira kuoma, yunifomu sangano uye zvakati wandei kuonana kuneta zvimiro pamwe hasha brittleness.
Sus304 ine yakakwira corrosion kuramba, inogona kunge iri pazasi tembiricha, tembiricha yemukamuri uye tembiricha yakakwira ipurasitiki yakakwira uye kuoma uye kutonhora kuri nani kuumba uye weldability.Nekuti iyo austenite haina shanduko yechikamu kana yapiswa, chaiyo piston tsvimbo haigone kusimbaradzwa nekupisa kurapwa uye inogona chete kupisa inorapwa kusimbisa simbi yekusaora.
Iyo chrome plating ukobvu hweiyo chaiyo piston tsvimbo maitiro inofanirwa kutariswa pamwe chete neiyo chaiyo.Mune piston rod chrome plating process, ukobvu hwe chrome layer ine hukama hwepedyo nekuoma kwepamusoro kwetsvimbo.Kana chrome plating ikaitwa, izvi zvinogona kutariswa zvinoenderana nezvinodiwa nemutengi kuitira kuti uwane kuita kwakanaka kwemhando.
