Ka wehewehe ʻana o ka ʻili pepa kila kila

N0.1 ʻōwili wela ma hope o ke kaʻina hana wela a me ka pickling.

2 b no ka mālama wela ʻana ma hope o ka ʻōwili anu, pickling, a i ʻole ka mālama like, a ma hope ma hope o ka ʻōlinolino maikaʻi.

Ka mālama wela ʻana ma hope o ka ʻōwili anu, pickling, a i ʻole ke kaʻina hana like a i ʻole ka ʻili matte.

wili ʻana he 3# 100~200# me nā huahana abrasive.

4# 150~180# wili ʻana me nā huahana abrasive.

ʻO ka HL granularity kūpono o ka polishing abrasive, ka ʻili o ka palaoa wili mau.

I mea e hōʻoia ai i ka hoʻoikaika ʻana o ke kila kila kila kila, ka ikaika tensile, ka elongation a me ka paʻakikī, a me nā waiwai mechanical e like me ke koi, pono e hoʻomehana ʻia ka wili kila kila kila ma mua o ka lawe ʻana, e like me ka mālama ʻana i ka hoʻonā a me ka mālama ʻana i ka ʻelemakule. ʻO ke kūpaʻa ʻana o ka papa kila kila kila kila ma muli o ka hui ʻana o nā mea hoʻohuihui (chromium, nickel, titanium, silicon a me ka alumini) a me ka hoʻonohonoho kūloko o ka wili kila kila kila, a he hana nui ia i ka CR. Loaʻa iā Chrome kahi kūpaʻa kemika kiʻekiʻe, hiki ke hana i kahi kiʻiʻoniʻoni passivating ma luna o ka ʻili kila, e hoʻokaʻawale i ka metala mai waho, e pale i ka papa mai ka oxidation, a hoʻonui i ke kūpaʻa ʻana o ka papa kila kila. Ma muli o ka hōʻino ʻana o ka kiʻiʻoniʻoni passive, hāʻule ke kūpaʻa ʻana o ka corrosion.
