Icyiciro cya Black Oxide Icyiciro cya kabiri 

Icyiciro cya 8.8 cyumukara wa okiside ya kabiri-nimbaraga ziciriritse-zifite imbaraga zifatanije zifata urudodo kumpande zombi hamwe na shanki idasomwe. Bahuza imikorere yubukanishi yizewe (800 MPa tensile imbaraga), kurinda ruswa yubukungu hifashishijwe igicapo cyoroshye cya Fe3O4, hamwe nogushiraho ibintu byinshi kumashini zinganda, amamodoka, hamwe nuburyo bukoreshwa.

1. Icyiciro cya 8.8 Ibyiciro

Kuri ISO 898-1, izina "8.8" risobanura imbaraga zingana zingana na MPa 800 hamwe numusaruro wa 0.8 (imbaraga zitanga 640 MPa). Yakozwe kuva mu kuzimya-no gutwarwa nicyuma giciriritse giciriritse, Icyiciro cya 8.8 gitanga imbaraga nziza-ku biciro.

Imbonerahamwe 1 - Ibyingenzi byingenzi bya mehaniki (ISO 898-1)

2. Umuti wa Oxide wirabura

Okiside yumukara (Fe3O4) ni imiti ihindura imiti ya micrometero 0.5-1.5, ikozwe no kwibizwa mu bwogero bwa nitrate ya alkaline ishyushye kuri 140-150C. Bitandukanye na electroplating, ntabwo itera impinduka zingana kandi nta hydrogène yinjira. Iyo ifunze hamwe namavuta yo kwirinda, itanga amasaha agera kuri 96 yo kurwanya umunyu.

3. Igishushanyo mbonera cya kabiri

Sitidi-ebyiri-ifite amaherezo ya robine (yinjijwe mu mwobo wafashwe) hamwe nimbuto (yemera ibinyomoro), itandukanijwe na shanki idasomwe. Uburebure bwa kanda ya burebure ni 1.0-1.5d hamwe nutubuto twa 2.0-3.0d, aho d ni diameter nominal.
