1. Jiri Vickers hardness tester nke welded akụkụ (Weld Vickers hardness test) usoro:
Ebe ọ bụ na microstructure nke akụkụ nkwonkwo nke welded (weld seam) n'oge ịgbado ọkụ ga-agbanwe n'oge usoro nhazi, ọ nwere ike ịmepụta njikọ na-adịghị ike na nhazi nke welded.Isi ike nke ịgbado ọkụ nwere ike igosipụta ozugbo ma usoro ịgbado ọkụ ahụ ọ bụ ihe ezi uche dị na ya.Mgbe ahụ ike siri ike Vickers Usoro nyocha bụ usoro na-enyere aka nyochaa ogo welds.Onye na-anwale ike siri ike nke Vickers nke Laizhou Laihua Hardness Tester Factory nwere ike mee nnwale ike na akụkụ welded ma ọ bụ ebe ịgbado ọkụ.Mgbe ị na-eji Vickers hardness tester iji nwalee akụkụ welded, ọnọdụ nnwale ndị a kwesịrị iburu n'uche:
Ịdị nro nke ihe nlele: Tupu ịnwale, anyị na-egweri weld ka a nwalee iji mee ka elu ya dị larịị, enweghị oyi akwa oxide, mgbawa na ntụpọ ndị ọzọ.
N'elu ahịrị etiti nke weld, were isi ihe n'elu agbagọ 100 mm ọ bụla maka nnwale.
Ịhọrọ ike ule dị iche iche ga-eme ka ọ pụta ìhè dị iche iche, ya mere, anyị ga-ahọrọ ike ule kwesịrị ekwesị tupu ule.
2. Otu esi eji Vickers hardness tester (micro Vickers hardness tester) chọpụta omimi nke oyi akwa siri ike?
Kedu ka esi achọpụta omimi nke oyi akwa siri ike nke akụkụ ígwè na ọgwụgwọ elu dị ka carburizing, nitriding, decarburization, carbonitriding, wdg, na akụkụ ígwè ndị a na-emenyụ emenyụ?
A na-eji omimi oyi akwa siri ike dị irè na-ekpo ọkụ n'ime mpaghara iji mee mgbanwe nhazi na arụmọrụ n'elu ígwè iji nweta mmetụta nke ịba ụba ike na ike na ike.Ọ na-ezo aka n' nha site na ntụzịaka kwụ ọtọ nke elu akụkụ ahụ ruo n'ókè microstructure akọwapụtara.Ma ọ bụ anya oyi akwa siri ike nke microhardness akọwapụtara.Ọtụtụ mgbe, anyị na-eji usoro ike ike gradient nke Vickers hardness tester iji chọpụta ịdị omimi oyi akwa siri ike nke workpiece.Ụkpụrụ bụ ịchọpụta ịdị omimi oyi akwa siri ike dị irè dabere na mgbanwe nke micro-Vickers siri ike site na elu ruo n'etiti akụkụ ahụ.
Maka usoro ọrụ akọwapụtara, biko rụtụ aka na vidiyo arụmọrụ Vickers hardness tester nke ụlọ ọrụ anyị.Nke a bụ mmalite ọrụ dị mfe:
Kwadebe ihe nlele dị ka achọrọ, na elu ule kwesịrị ịchacha na elu enyo.
Họrọ ike nnwale nke Vickers hardness tester.A na-atụ gradient ike ike n'ebe abụọ ma ọ bụ karịa.A na-atụ ike ike Vickers n'otu ahịrị ma ọ bụ karịa n'akụkụ elu.
N'ịbụ onye na-ese usoro siri ike dabere na data a tụrụ, enwere ike ịmara na ebe kwụ ọtọ site na elu akụkụ ahụ ruo 550HV (n'ozuzu) bụ omimi oyi akwa siri ike dị irè.
3. Olee otú iji Vickers hardness tester maka mgbaji siri ike ule ( mgbaji siri ike Vickers ule usoro)?
Njiji siri ike bụ uru nguzogide ihe ahụ gosipụtara mgbe ihe nlere anya ma ọ bụ akụrụngwa gbajiri n'okpuru ọnọdụ anaghị akwụsi ike dị ka mgbawa ma ọ bụ ntụpọ yiri mgbawa.
Mgbaji siri ike na-anọchite anya ikike nke ihe iji gbochie ịgbasa mgbawa ma bụrụ ihe na-egosi ọnụọgụgụ nke ihe siri ike.
Mgbe ị na-eme ule ike mgbaji mgbaji, buru ụzọ kpochaa elu nke nlele ule na elu enyo.Na Vickers hardness tester, jiri conical diamond indenter nke Vickers hardness tester mee ntinye n'elu a na-egbu maramara nke nwere ibu 10Kg.A na-emepụta mgbawa ndị a na-emepụta ihe na akụkụ anọ nke akara ahụ.Anyị na-ejikarị ihe nnwale ike ike Vickers nweta data ike mgbaji.
