1. Jiri usoro nnwale ike Vickers nke akụkụ ndị a gbanyere agbakọta (ule ike Weld Vickers):
Ebe ọ bụ na obere nhazi nke akụkụ nkwonkwo nke njikọta nke njikọta (njikọ njikọta) n'oge njikọta ga-agbanwe n'oge nhazi, ọ nwere ike ịmepụta njikọ na-adịghị ike na nhazi njikọta ahụ. Ike nke njikọta ahụ nwere ike igosipụta ozugbo ma usoro njikọta ahụ ọ dị mma. Mgbe ahụ ike Vickers Usoro nyocha bụ usoro nke na-enyere aka inyocha ịdị mma nke njikọta ahụ. Onye nnwale ike Vickers nke Laizhou Laihua Hardness Tester Factory nwere ike ime nnwale siri ike na akụkụ njikọta ma ọ bụ ebe njikọta. Mgbe ị na-eji onye nnwale ike Vickers nwalee akụkụ njikọta ahụ, a ga-ahụ ọnọdụ nnwale ndị a:
Nha nke ihe nlele ahụ: Tupu anyị anwale ya, anyị na-egweri ihe e ji agwakọta ya ka e wee nwalee ya ka elu ya dị ire ụtọ, na-enweghị ihe mkpuchi oxide, mgbawa na ntụpọ ndị ọzọ.
N'ahịrị etiti nke weld ahụ, were otu ebe n'elu gbagọrọ agbagọ kwa 100 mm maka nnwale.
Ịhọrọ ike ule dị iche iche ga-ebute nsonaazụ dị iche iche, yabụ anyị ga-ahọrọ ike ule kwesịrị ekwesị tupu anyị anwale ya.
2. Kedu otu esi eji ihe nnwale ike Vickers (micro Vickers hardness tester) chọpụta omimi nke oyi akwa siri ike?
Kedu otu esi achọpụta omimi nke akwa siri ike nke akụkụ ígwè site na iji ọgwụgwọ elu dị ka carburizing, nitriding, decarburization, carbonitriding, wdg, na akụkụ ígwè nke induction emenyụọla?
A na-ejikarị omimi oyi akwa siri ike eme ihe iji kpoo elu ahụ ọkụ n'ógbè ahụ iji mee ka mgbanwe nhazi na arụmọrụ dị n'elu ígwè ahụ nweta mmetụta nke mmụba nke ike na ike na ike. Ọ na-ezo aka na nha site na ntụle kwụ ọtọ nke elu akụkụ ahụ ruo na ókèala microstructure akọwapụtara. Ma ọ bụ anya oyi akwa siri ike nke microhardness akọwapụtara. Ọtụtụ mgbe, anyị na-eji usoro ike gradient nke Vickers hardness tester iji chọpụta omimi oyi akwa siri ike nke ọrụ ahụ. Ụkpụrụ bụ ịchọpụta omimi oyi akwa siri ike nke ọma dabere na mgbanwe na ike micro-Vickers site na elu ruo etiti nke akụkụ ahụ.
Maka ụzọ ọrụ pụrụ iche, biko lee vidiyo ọrụ Vickers hardness tester nke ụlọ ọrụ anyị. Nke a bụ okwu mmeghe dị mfe:
Kwadebe ihe nlele ahụ dịka ọ dị mkpa, a ga-etekwa elu nnwale ahụ ka ọ bụrụ enyo.
Họrọ ike nnwale nke ihe nnwale siri ike nke Vickers. A na-atụ gradient siri ike n'ebe abụọ ma ọ bụ karịa. A na-atụ ike nke Vickers n'otu ma ọ bụ karịa ahịrị ndị yiri ya nke kwụ ọtọ n'elu.
Site na iji data a tụrụ atụ, a pụrụ ịmata na anya kwụ ọtọ site n'elu akụkụ ahụ ruo 550HV (n'ozuzu) bụ omimi oyi akwa siri ike nke ọma.
3. Kedu otu esi eji ihe nnwale ike Vickers maka nnwale ike mgbawa (usoro nnwale ike Vickers)?
Ike nke mgbawa bụ uru iguzogide nke ihe ahụ na-egosi mgbe ihe nlele ma ọ bụ akụkụ ahụ gbawara n'okpuru ọnọdụ na-adịghị agbanwe agbanwe dịka mgbawa ma ọ bụ ntụpọ dị ka mgbawa.
Ike nke mgbawa na-anọchite anya ikike nke ihe iji gbochie mgbasa nke mgbawa ma bụrụ ihe ngosi ọnụọgụ nke ike nke ihe.
Mgbe ị na-eme ule ike mgbawa, buru ụzọ hichaa elu ihe nlele ahụ gaa n'elu enyo. N'elu ihe nnwale ike Vickers, jiri ihe nrịbama conical nke ihe nnwale ike Vickers mee oghere n'elu ihe a na-egbuke egbuke nke nwere ibu 10Kg. A na-emepụta mgbawa ndị e mere tupu oge eruo na nsọtụ anọ nke akara ahụ. Anyị na-ejikarị ihe nnwale ike Vickers enweta data ike mgbawa.
