Hukama huri pakati pe induction kuomesa kuomarara uye kupfeka kuramba
Ukama huripo induction hardening kuoma uye kupfeka kuramba
Kupfeka kupikisa hakusi kungoenderana chete nezvinhu, asiwo kune chimiro chekupfeka. Mapfekero akajairika anosanganisira abrasive kupfeka, anonamira kupfeka, oxidative kupfeka, uye kuneta kupfeka.
1. Kuneta kunopera, kuneta kunopera kunobva pane metallurgical quality, yakadai seporosity, pores, mavara machena, kwete-metallic inclusions, nezvimwewo, uye haina chokuita nekuoma. Kuvandudza iyo metallurgical quality inogona kuvandudza kuneta kupfeka kuramba kwesimbi.
2. Pasi pemamiriro ekupfekedza abrasive, zvinhu zvikuru zvinokanganisa kupfeka kusagadzikana ndiko kuoma uye sangano. Kana mutoro wekukanganisa uri diki, kupikisa kupfeka kunoenderana nekuomarara, ndiko kuti, kuomarara kunogona kushandiswa kuyera kuramba kupfeka. Kana iyo yekukanganisa mutoro yakakura, kupfeka kuramba kunokanganiswawo nesimba uye kuoma. Panguva ino, pamusoro Kuomarara hakusi kwakakwirira zviri nani, asi pane yakakodzera kuomarara siyana, uye kupfeka kuramba kunoderera mushure mekuoma kunodarika imwe kukosha. Chimiro, huwandu uye kugovera kwesimbi carbides kune zvakakosha pakupokana kwekupfeka.
3. Nokuda kwekunamatira kupfeka, mamiriro acho akaoma. Kazhinji, brittle zvinhu uye yakakwirira melting point zvinhu zvinopokana nekunamira kupfeka. Kuderedza friction coefficient inogona kuvandudza kupfeka kuramba. Zvishandiso zvine kuoma kwakanyanya zvinobatsira kuderedza friction coefficient. Kupfeka kuramba kwakanaka, ndicho chikonzero.
- Kupfeka kweoxidative kunonyanya kuenderana nekupararira kwenzvimbo yesimbi, zvimiro zveiyo oxide firimu yakaumbwa, uye kusimba kwekubatana kweiyo oxide firimu uye substrate. Pasinei nekuoma. Nokudaro, zvinogona kuonekwa kuti kuoma kwakabatana zvakanyanya nekupfeka kushorwa, asi haisi iyo chete.
