Ubunzima bombhobho wensimbi bubhekisela kwikhono lezinto eziphathekayo zokumelana ne-deformation phantsi kwamandla angaphandle. Ubunzima sesinye sezibonakaliso ezibalulekileyo zokusebenza kwezinto.
Kwimveliso kunye nokusetyenziswa kwemibhobho yensimbi, ukuzimisela kobunzima babo kubaluleke kakhulu. Ukuqina kwemibhobho yentsimbi kunokulinganiswa ngabavavanyi bobulukhuni abahlukeneyo njengeRockwell, iBrinell, kunye neVickers eveliswe yiLaizhou Laihua Testing Instrument Factory, enokuthi yenziwe ngokwezifiso njengoko kufuneka. Ezona ndlela zomlinganiselo zibandakanya oku kulandelayo:
1. Indlela yokuvavanya ubulukhuni be-Rockwell
Uvavanyo lobulukhuni be-Rockwell okwangoku yindlela esetyenziswa kakhulu, phakathi kwayo i-HRC yesibini kuphela kwi-Brinell hardness HB kumgangatho wepayipi yensimbi. Ilinganisa ubunzulu bokungena kwaye ingasetyenziselwa ukulinganisa imathiriyeli yentsimbi ukusuka ethambileyo kakhulu ukuya kokuqina kakhulu. Ilula kunendlela yokuvavanya iBrinell.
2. Indlela yokuvavanya ubulukhuni beBrinell
Indlela yokuvavanya ubulukhuni beBrinell nayo isetyenziswa ngokubanzi kwindawo yoshishino. Isetyenziswa ngokubanzi kwimigangatho yepayipi yentsimbi engenamthungo. Ubunzima bezinto eziphathekayo budla ngokubonakaliswa yi-diameter ye-indentation. I-intuitive kwaye ilungele, kodwa ayisebenzi kwimibhobho yentsimbi eqinile okanye encinci.
3. Indlela yokuvavanya ubulukhuni beVickers
Uvavanyo lobulukhuni beVickers lukwasetyenziswa ngokubanzi. Ineenzuzo eziphambili zeBrinell kunye neRockwell iindlela zokuvavanya, kodwa zinqoba izinto ezingalunganga. Ifanelekile ukuvavanywa kobunzima bezinto ezahlukeneyo, kodwa ayifanelekanga kwiisampuli ezinamadamitha amancinci. Akulula njengendlela yokuvavanya i-Rockwell kwaye ayifane isetyenziswe kwimigangatho yepayipi yensimbi.
