Izikhonkwane ziyizinto ezibalulekile zokuxhumanisa ngomshini, futhi izinga lazo lobulukhuni lingenye yezinkomba ezibalulekile zokulinganisa ikhwalithi yazo.
Ngokwezindlela ezahlukene zokuhlola ubulukhuni, izindlela zokuhlola ubulukhuni zeRockwell, Brinell kanye neVickers zingasetshenziswa ukuhlola ubulukhuni bezinamathiseli.
Ukuhlolwa kobulukhuni be-Vickers kuhambisana ne-ISO 6507-1, ukuhlolwa kobulukhuni be-Brinell kuhambisana ne-ISO 6506-1, kanye nokuhlolwa kobulukhuni be-Rockwell kuhambisana ne-ISO 6508-1.
Namuhla, ngizokwethula indlela yobulukhuni be-micro-Vickers ukuze ngilinganise ukuhlukaniswa kobuso kanye nokujula kwengqimba yokuhlukaniswa kobuso yezinamathiseli ngemva kokwelashwa ngokushisa.
Ukuze uthole imininingwane, sicela ubheke indinganiso kazwelonke ye-GB 244-87 ukuze uthole imithethonqubo yomkhawulo wokulinganisa ngokujula kwengqimba ekhishwe ku-carburetion.
Indlela yokuhlola i-micro-Vickers yenziwa ngokuhambisana ne-GB/T 4340.1.
Isampula ngokuvamile ilungiswa ngokuthatha amasampula, ukugaya kanye nokupholisha, bese ibekwa kumshini wokuhlola ubulukhuni obuncane ukuze kutholakale ibanga ukusuka ebusweni kuya endaweni lapho inani lobulukhuni elidingekayo selifinyelelwe khona. Izinyathelo ezithile zokusebenza zinqunywa izinga lokuzenzakalela komhloli wobulukhuni osetshenzisiwe ngempela.
