Njira yoyesera yolimba ya zomangira

Ma fasteners ndi zinthu zofunika pakulumikizana kwamakina, ndipo mulingo wawo wowuma ndi chimodzi mwazizindikiro zofunika kuyeza mtundu wawo.

Malinga ndi njira zosiyanasiyana zoyesera kuuma, njira zoyesera za Rockwell, Brinell ndi Vickers zitha kugwiritsidwa ntchito kuyesa kuuma kwa zomangira.

Mayeso a Vickers hardness amagwirizana ndi ISO 6507-1, mayeso a Brinell hardness amagwirizana ndi ISO 6506-1, ndipo mayeso a Rockwell hardness amagwirizana ndi ISO 6508-1.

Lero, ndikuwonetsa njira yolimba ya Micro-Vickers yoyezera kutsika kwapamtunda komanso kuya kwa zomangira zotsekera pambuyo pa chithandizo cha kutentha.

Kuti mumve zambiri, chonde onani muyezo wadziko lonse wa GB 244-87 wamalamulo oletsa muyeso pakuzama kwa wosanjikiza wa decarburized.

Njira yoyesera ya Micro-Vickers imachitika molingana ndi GB/T 4340.1.

Zitsanzozo nthawi zambiri zimakonzedwa ndi sampuli, kugaya ndi kupukuta, kenaka zimayikidwa pa micro-hardness tester kuti azindikire mtunda kuchokera pamwamba mpaka pamene mtengo wovuta wofunikira wafika.Masitepe enieni ogwirira ntchito amatsimikiziridwa ndi kuchuluka kwa automation ya hardness tester yomwe imagwiritsidwa ntchito.
