Izixhumi ziyizici ezibalulekile zokuxhuma ngomshini, futhi izinga labo lokuqina lingenye yezinkomba ezibalulekile zokulinganisa ikhwalithi yazo.
Ngokwezindlela ezihlukene zokuhlola ubulukhuni, izindlela zokuhlola ubulukhuni be-Rockwell, Brinell kanye ne-Vickers zingasetshenziswa ukuhlola ubulukhuni bezinsimbi.
Ukuhlolwa kokuqina kwe-Vickers kuhambisana ne-ISO 6507-1, ukuhlolwa kokuqina kwe-Brinell kuhambisana ne-ISO 6506-1, kanti ukuhlolwa kokuqina kwe-Rockwell kuhambisana ne-ISO 6508-1.
Namuhla, ngizokwethula indlela yobulukhuni be-Micro-Vickers ukukala ukususwa kwe-carburization kanye nokujula kongqimba lwe-fasteners olwehlisiwe ngemuva kokwelashwa kokushisa.
Ukuze uthole imininingwane, sicela ubhekisele ku-GB 244-87 ejwayelekile kazwelonke ngemithetho yomkhawulo wokulinganisa ekujuleni kwesendlalelo se-decarburized.
Indlela yokuhlola ye-Micro-Vickers yenziwa ngokuhambisana ne-GB/T 4340.1.
Isampula ngokuvamile ilungiswa ngesampula, ukugaywa nokupholishwa, bese ibekwa kumhloli wobulukhuni obuncane ukuze kutholwe ibanga ukusuka phezulu kuya endaweni lapho inani lobulukhuni obudingekayo lifinyelelwe khona.Izinyathelo ezithile zokusebenza zinqunywa izinga lokuzenzakalela kwesihloli sokuqina esisetshenziswa ngempela.
