Indlela yokuvavanya ubulukhuni beefasteners

I-Fasteners zizinto ezibalulekileyo zoxhumo lomatshini, kwaye umgangatho wabo wobunzima ungenye yezibonakaliso ezibalulekileyo zokulinganisa umgangatho wabo.

Ngokweendlela ezahlukeneyo zokuvavanya ubulukhuni, iindlela zokuvavanya ubulukhuni beRockwell, iBrinell kunye neVickers zinokusetyenziselwa ukuvavanya ukuqina kweziqhoboshi.

Uvavanyo lobulukhuni beVickers luhambelana ne-ISO 6507-1, uvavanyo lobulukhuni lwe-Brinell luhambelana ne-ISO 6506-1, kwaye uvavanyo lobunzima be-Rockwell luhambelana ne-ISO 6508-1.

Namhlanje, ndiza kwazisa indlela yobulukhuni beVickers yokulinganisa i-decarburization yomphezulu kunye nobunzulu bomaleko we-decarburized of fasteners emva konyango lobushushu.

Ukufumana iinkcukacha, nceda ubhekisele kumgangatho kazwelonke we-GB 244-87 kwimimiselo yomlinganiselo womlinganiselo kubunzulu bomaleko we-decarburized.

Indlela yokuvavanya i-micro-Vickers iqhutyelwa ngokuhambelana ne-GB / T 4340.1.

Isampuli ilungiswa ngokubanzi ngesampuli, ukugawula kunye nokupolisha, kwaye emva koko ibekwe kwi-micro-hardness tester ukubona umgama ukusuka kumphezulu ukuya kwindawo apho ixabiso lobunzima obufunekayo lifikeleleke.Amanyathelo okusebenza athile amiselwa yinqanaba lokuzenzekela komvavanyi wobulukhuni osetyenziswe ngokwenene.
