Kwishingikiriza gusa kuri Ra (ubushyuhe bw'ubuso busanzwe) ntabwo bihagije iyo ugereranije electropolishing (EP) na mechanical polishing (MP). Nubwo inzira zombi zishobora kugabanya Ra, zitanga ubusugire bw'ubuso butandukanye cyane, bityo bigatuma imikorere itandukana cyane.
1. Itandukaniro ry'ibanze mu mikorere
• Gusukura hakoreshejwe ikoranabuhanga (MP): Uburyo bwo gukata, gusiga, no kugorora ubuso. Bukuraho ibintu binyuze mu guhindura imiterere ya pulasitiki, bigasiga urwego rukora cyane kandi rugoramye.
• Electropolishing (EP): Uburyo bwa elegitoroniki bukuraho mu buryo bwihariye imisozi mito cyane (ahantu hirengeye) kuva hejuru kugeza mu bibaya. Bukuraho iyoni y'ibintu hakoreshejwe iyoni, nta guhangayika cyangwa gusiga ibara.
2. Icyo Ra atakubwira
Gutunganya ibyuma bikoresha amashanyarazi
“Ubuzima” ku buso busiga uduce duto tw’icyuma, uduce duto tw’icyuma, uduce duto tw’icyuma, n’igice gikonje cyane. Bitanga ubuso busukuye, budafite imiti cyangwa urwego rwangiritse.
Ubudahangarwa bw'ubushyuhe Bushobora gukora imyenge no kumena firime ya okiside idakora. Uduce tw'umucanga dushobora gutangira gushonga. Bikuraho urwego rwa chromium rwangiritse kandi bikongera chromium hejuru, bigatuma habaho firime ikomeye kandi isanzwe idakora.
Isuku n'isuku Ifite iminkanyari mu cyerekezo n'ibibaya bito bifata bagiteri, amazi n'udukoko. Itanga ubuso butari mu cyerekezo, bworoshye kandi budafite icyuho, byoroshye gusukura no gutobora (ni ingenzi ku miti, ibiribwa, ikoranabuhanga rya biotech).
Imikorere y'umunaniro Imihangayiko yo gukurura ibisigazwa n'inenge zo hejuru bigabanya igihe cyo kunanirwa. Bikuraho ibintu bitera stress n'urwego rwangiritse; akenshi byongera imbaraga zo kunanirwa (cyane cyane mu byuma bikomeye).
Imiterere y'imiterere y'ubutaka Igoye Ntishobora kugera ku myenge y'imbere, ku migozi, ku mfuruka, cyangwa ku bice bigoye. Ifata neza ubuso bwose bwagaragaye, harimo n'ahantu bigoye kugera, kandi ikuraho ubushyuhe icyarimwe.
3. Agaciro gasanzwe ka Ra – Umutego
• Gusukura hakoreshejwe ikoranabuhanga bishobora kugera ku gipimo cya Ra kiri hasi cyane (urugero, < 0.05 µm) – ariko ubwo buryo bworoshye bushobora kuba buhishe ubuso bwangiritse.
• Gutunganya hakoreshejwe amashanyarazi biha agaciro ka Ra kari hagati ya 0.2–0.8 µm, gashobora kugaragara nk'aho "gakomeye" mu mibare. Ariko, ubuso bwaho burasukuye mu buryo bwa shimi, nta stress, kandi burwanya ingese cyane.
Mu bipimo byinshi (urugero, ASME‑BPE ku bikoresho bya farumasi), Ra yihariye irakenewe, ariko electropolishing irasabwa cyane kuko itanga ubuso budafite umwuka, atari umubare muto gusa.
Gutwara bya nyuma
Ra ni umubare gusa - upima ubusumbane bw'uburebure, ntabwo ari ubwiza bw'ubuso.
Gutunganya hakoreshejwe amashanyarazi no gutunganya ibikoresho mu buryo bwa mekanike ni ibintu bitandukanye cyane kandi bifite intego zitandukanye. Guhitamo neza biterwa n'ibyo porogaramu yawe isaba, ntabwo biterwa no gukurikirana Ra nkeya cyane.
