Mashiinka Mashiinka Mashiinka Adag ee Universal / Mashiinka Imtixaanka Qalbi Xumida
Sharaxaad:
1. Hardness waa mid ka mid ah astaamaha makaanikada muhiimka ah ee maaddada halka tijaabinta adkaanta ay tahay habka ugu dhaqsaha badan uguna tijaabinta dhaqaalaha, sidoo kale waa hab muhiim ah oo lagu xukumo tayada maaddada birta ama qeybaha ay ka kooban tahay. Astaamaha makaanikada ee inta badan qalabka birta sida xoogga, daalka, qulqulatada iyo daal la'aanta waxaa lagu tijaabin karaa qiyaas ahaan iyada oo loo marayo baaritaanka adkaanta.
2. Gawaarida Gawaarida Brinell Rockwell & Vickers Hardness Tester, oo ah tijaabo qallafsan oo shaqooyin badan leh oo leh Brinell, Rockwell & Vickers 3 nooc oo habab tijaabo ah iyo 7 tilaabo oo tijaabooyin xoog ah ayaa dabooli doona baahiyaha noocyada badan ee cabbiraadda adkaanta. Qalabka waxaa loo qaatay isbeddel otomaatig ah si loo raro, loo dego loona soo dejiyo xoogga baaritaanka, sidaas darteed qalliinka qalabkan waa mid fudud, fudud oo dhaqso leh.
