Kuvimba chete neRa (average surface roughness) hakuna kukwana kana tichienzanisa electropolishing (EP) nemechanical polishing (MP). Kunyange zvazvo maitiro ese ari maviri achigona kuderedza Ra, anogadzira kusiyana kukuru kwehuso uye, nekudaro, mashandiro akasiyana zvikuru.
1. Musiyano Mukuru Mukuita
• Kupukuta Nemuchina (MP): Maitiro ekukwesha anocheka, kusvibisa, uye kutetepa pamusoro. Anobvisa zvinhu nekuchinja kwepurasitiki, zvichisiya layer yakashanda zvakanyanya uye yakakombama.
• Kuchenesa nemagetsi (EP): Maitiro emagetsi anonyungudutsa misoro midiki (nzvimbo dzakakwirira) kubva pamusoro kusvika kumipata. Anobvisa maayoni nezvinhu nemaayoni, pasina kumanikidzwa kana kusvuuka.
2. Izvo Ra Asingakuudzi
Kupukuta Kwemichina Yekushongedza Nemagetsi
"Hutano" Pamusoro Inosiya zvidimbu zvinokwenya zvakaputirwa, simbi yakazorwa, mitswe midiki, uye jira rakanyorova zvakanyanya. Inogadzira nzvimbo yakachena, yakachena ine makemikari isina tsvina yakaputirwa kana jira rakaremara.
Kuramba Kuora Kunogona kugadzira mitswe uye kupwanya firimu repasi pevhu re oxide. Grit yakasungirirwa inogona kutanga kudonha. Inobvisa chromium-depleted layer uye inopfumisa pamusoro ne chromium, zvichiita firimu repasi pevhu rakasimba, rakafanana.
Kuchena uye Hutsanana Ine makwara akananga uye mipata midiki inobata mabhakitiriya, mvura, uye tunhu tudiki. Inoburitsa nzvimbo isina divi, yakatsetseka, isina mitswe iri nyore kuchenesa uye kuuraya utachiona (yakakosha kune mishonga, chikafu, biotech).
Kushanda Nekuneta Kushushikana kwasara uye zvikanganiso pamusoro pechinhu kunoderedza nguva yekuneta. Kubvisa zvinosimudzira kushushikana uye jira rakakuvara; kazhinji kunovandudza simba rekuneta (kunyanya mu alloys dzine simba rakawanda).
Magadzirirwo Akaomesesa Haakwanise kusvika pamaburi emukati, shinda, makona, kana zvikamu zvakaoma. Anogadzirisa zvakaenzana nzvimbo dzese dzakavhurika, kusanganisira nzvimbo dzakaoma kusvika, uye anobvisa maburi panguva imwe chete.
3. Maitiro Akajairika eRa - Musungo
• Kupolisha kwemuchina kunogona kuita kuti Ra iderere zvakanyanya (semuenzaniso, < 0.05 µm) - asi kupfava ikoko kungave kwakadzika, kuchivanza pasi pevhu rakakuvara.
• Kuchenesa nemagetsi kunowanzoita kuti Ra ive pakati pe0.2–0.8 µm, izvo zvingaita se "zvakakombama" kana tichitarisa nhamba. Zvisinei, pamusoro payo pakachena nemakemikari, hapana kushushikana, uye hapagoni ngura zvakanyanya.
Muzviyero zvakawanda (semuenzaniso, ASME‑BPE yemidziyo yemishonga), Ra chaiyo inodiwa, asi electropolishing inokurudzirwa zvikuru nekuti inopa nzvimbo isina chinhu, kwete nhamba shoma chete.
Kutora Kwekupedzisira
Ra ingori nhamba - inoyera kutsauka kwehurefu, kwete kunaka kwenzvimbo.
Kupolisha nemagetsi uye kupolisha nemagetsi maitiro akasiyana zvachose anobatsira zvinangwa zvakasiyana. Sarudzo chaiyo inoenderana nezvinodiwa nebasa remushandisi wako, kwete pakutevera Ra yakaderera.
