N'ihi ike ike Vickers na ule microhardness, akụkụ diamond nke indenenter ejiri maka nha bụ otu. Kedu ka ndị ahịa kwesịrị isi họrọ ihe nnwale ike ike Vickers? Taa, m ga-akọwa nkenke dị iche n'etiti Vickers hardness tester na microhardness tester.
Nnwale ikike nha nkewa Vickers hardness na microhardness tester scale
Vickers hardness tester: nnwale ike F≥49.03N ma ọ bụ≥HV5
Obere ibu Vickers siri ike: ike nnwale 1.961N≤F <49.03N ma ọ bụ HV0.2 ~ <HV5
Ihe nleba anya Microhardness: ike nnwale 0.09807N≤F <1.96N ma ọ bụ HV0.01 ~ HV0.2
Yabụ kedu ka anyị kwesịrị isi họrọ ike nnwale kwesịrị ekwesị?
Anyị kwesịrị ịgbaso ụkpụrụ na ibu indentation, ndị ọzọ ziri ezi nha nha ma ọ bụrụ na workpiece ọnọdụ na-ekwe, na-ahọrọ dị ka mkpa, n'ihi na nta indentation, nke ukwuu njehie na-atụ diagonal ogologo, nke ga-eduga na-abawanye na njehie nke ike ike uru.
A na-akwado ike nnwale nke microhardness tester: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N (500gf) (1000gf) (19.6N (2.0Kgf) nhọrọ)
A na-akwadokarị ịdị elu ahụ: ugboro 100 (nleba anya), ugboro 400 (atụ)
Enwere ike kewaa ọkwa ike ule nke Vickers hardness tester n'ime: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (0.3Kg.N), 5.0Kg. 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (ụdị dị iche iche nwere dị iche iche ule nhazi nhazi.)

Ihe nnwale ike ike nke Vickers nke Shandong Shancai/Laizhou Laihua Ngwa nnwale nwere ike ime ule ike n'akụkụ welded ma ọ bụ ebe ịgbado ọkụ.
Dị ka atụle hardness uru, àgwà nke weld na metallurgical mgbanwe nwere ike ikpe. Dịka ọmụmaatụ, isi ike dị oke elu nwere ike ịbụ n'ihi ntinye oke ọkụ n'oge ịgbado ọkụ, ebe isi ike dị ala nwere ike igosi ezughị oke ịgbado ọkụ ma ọ bụ nsogbu ịdị mma ihe onwunwe.
Sistemụ nha nke Vickers ahaziri ga-eme mmemme nnwale akpaka zuru oke wee gosipụta ma dekọ nsonaazụ kwekọrọ.
Maka nsonaazụ nke ule nha, enwere ike iwepụta akụkọ eserese kwekọrọ na akpaaka.
Ọ dị mkpa iburu n'obi na mgbe ị na-ahọrọ mpaghara nnọchiteanya nkenkeweld dị ka ebe nyocha, jide n'aka na mpaghara a enweghị pores, mgbawa ma ọ bụ ntụpọ ndị ọzọ nwere ike imetụta nsonaazụ ule.
Ọ bụrụ na ị nwere ajụjụ ọ bụla gbasara nyocha weld, nweere onwe gị ịkpọtụrụ anyị
