Ama-Fasteners ayizinto ezibalulekile zokuxhumeka kwemishini, futhi izinkambiso zazo zingenye yezinkomba ezibalulekile ukukala ikhwalithi yazo.
Ngokuya ngezindlela ezahlukahlukene zokuhlola izinhlanzi, i-Rocwell, i-Brinell kanye nezindlela zokuhlola izinkambiso ze-shickers zingasetshenziswa ukuvivinya ubulukhuni be-fasteners.
Ukuhlolwa kwe-Heaver Hardness kuhambisana ne-ISO 6507-1, ukuhlolwa kwe-Brinell Harveness kuhambisana ne-ISO 6506-1, kanti ukuhlolwa kobulukhuni be-Rocwell kuhambisana ne-ISO 6508-1.
Namuhla, ngizokwethula indlela ye-Micro-Vickers Hardeness indlela yokulinganisa ukukhiqizwa kwe-decorderaval kanye nokujula kwesendlalelo se-fasteraders ngemuva kokwelashwa okushisa.
Ngemininingwane, sicela ubheke kwi-National Standard GB 244-87 yemithetho yemkhawulo yokulinganisa ekujuleni kwesendlalelo se-decorburised.
Indlela yokuhlola i-Micro-Vickers yenziwa ngokuya nge-GB / T 4340.1.
Isampula ngokuvamile lilungiselelwe ngesampula, ukugaya nokuphoqelela, bese lifakwa kumhloli we-micro-hardness ukuthi athole ibanga ukusuka phezulu kuya endaweni lapho kufinyelelwa khona inani lokuqina kanzima. Izinyathelo ezithile zokusebenza zinqunywa ngezinga le-automation of the Hardness tester asetshenziswa empeleni.
