IBanga eliMnyama leOxide eliPhelele kabini 

IBanga lesi-8.8 i-oksidi emnyama enesiphelo esiphindwe kabini izikhonkwane zokuqina eziphakamileyo ezinamandla ezinomsonto kuzo zombini iziphelo ezineziko le-shank elingafundwanga. Badibanisa ukusebenza okuthembekileyo komatshini (i-800 MPa amandla okuqina), ukukhuselwa kwe-corrosion yezoqoqosho ngokusebenzisa i-Fe3O4 encinci yokuguqula i-coating, kunye nofakelo oluguquguqukayo koomatshini bemizi-mveliso, iimoto, kunye nezicelo zesakhiwo.

1. Ukuhlelwa kweBakala 8.8

Ngokwe-ISO 898-1, ukutyunjwa kwe-"8.8" kuthetha amandla anqabileyo angama-800 MPa kunye nomlinganiselo wesivuno se-0.8 (isivuno samandla 640 MPa). Yenziwe ngentsimbi ye-alloy carbon alloy ecinyiweyo kunye nephakathi, iBakala 8.8 libonelela ngolungelelwaniso olugqwesileyo lweendleko.

2. Unyango lwe-Black oxide Surface

I-oksidi emnyama (i-Fe3O4) i-chemical conversion coating 0.5-1.5 micrometers ubukhulu, eyenziwa ngokuntywiliselwa kwindawo yokuhlamba i-alkaline nitrate kwi-140-150C. Ngokungafaniyo ne-electroplating, ayibangeli tshintsho lwe-dimensional kwaye akukho hydrogen embrittlement. Xa ivalwe ngeoyile yokuthintela umhlwa, ibonelela ngeeyure ezingama-96 zokuxhathisa isitshizi setyuwa.

3. Uyilo lwe-Stud oluPhelele kabini

I-double-end stud ine-tap end (i-screwed emngxunyeni oxutywe) kunye ne-nut end (iyamkela i-nut), ihlukaniswe yi-shank engafundwanga. Ubude besiphelo sempompo ngokuqhelekileyo yi-1.0-1.5d kunye ne-nut end 2.0-3.0d, apho u-d yi-diameter yegama.
