Isi ike na ebe dị n'akụkụ weld ahụ nwere ike inye aka nyochaa nbibi nke weld ahụ, si otú ahụ na-enyere gị aka ikpebi ma weld nwere ike achọrọ, ya mere usoro nyocha ike nke weld Vickers bụ usoro na-enyere aka nyochaa àgwà nke weld.
Shandong Shancai /Laizhou Laihua Testing Instrument Company's Vickers hardness tester nwere ike ime ule ike n'akụkụ welded ma ọ bụ ebe ịgbado ọkụ.Mgbe ị na-anwale ike nke ebe ịgbado ọkụ, a ga-eme nha ọtụtụ ihe n'ebe dị anya site na nsọtụ ihe nlele ahụ ma ọ bụ n'elu ebe ịgbado ọkụ.Mgbe ị nwetasịrị ntinye nrịbama ọtụtụ, enwere ike tụọ uru ike siri ike site na nha na-aga n'ihu ma nwee ike nweta eserese mgbanaka.
Mgbe ị na-eji Vickers hardness tester iji nwalee akụkụ welded, ọnọdụ nnwale ndị a kwesịrị iburu n'uche:
1. Ịdị nro nke ihe atụ: Tupu ịnwale, anyị na-egweri weld a ga-anwale iji mee ka elu ya dị mma, na-enweghị oyi akwa oxide, mgbawa na ntụpọ ndị ọzọ.
2. N'ahịrị etiti nke weld, were isi ihe dị n'elu agbagọ 100 mm ọ bụla maka ule.
3. Ịhọrọ ụdị ule dị iche iche ga-eme ka ọ pụta ìhè dị iche iche, n'ihi ya, anyị ga-ahọrọ ike ule kwesịrị ekwesị tupu ule.
Ihe nleba anya microhardness nwere ihe achọrọ maka imecha elu nke ihe nlele a nwalere, nke kwesịrị iji nlezianya kwadebe dị ka ihe nlele metallographic si dị.
Ụkpụrụ ule microhardness na usoro ule microhardness bụ otu ihe ahụ dị ka ike siri ike nke Vickers, mana ibu a na-eji dị obere karịa ike siri ike Vickers dị ala, na-abụkarị ihe na-erughị 1000g, na ntinye ntinye bụ naanị microns ole na ole na ole na ole abụọ. microns, yabụ ule microhardness na-enye ụzọ dị mma maka ịmụ ihe microstructure nke oyi akwa nwere ike.A na-eji ya eme ihe n'ọtụtụ ebe iji chọpụta ike nke oge ọ bụla n'elu na n'ime oyi akwa.
A na-egosipụtakarị akara nke microhardness site na HV, na ụkpụrụ mkpebi ya na usoro ya yiri usoro siri ike nke Vickers.Sistemụ nbudata, sistemu nha na ntinye nkenke nke ihe nleba anya microhardness na-achọsi ike karịa nke ihe nnwale ike ike Vickers dị obere.Ka ọ dị ugbu a, a na-eji microhardness tester eme ihe n'ụdị arụ ọrụ dị mkpa, na n'ihi na mmụba ahụ nwere ike iru ugboro 400, a na-ejikarị ya dị ka microscope metallographic dị mfe.
N'ime usoro eji eme ihe, a ga-akwụ ụgwọ nlebara anya na ibu, micrometer na indenter nke microhardness tester, nke a ga-enyocha tupu ejiri ya, a na-ejikwa ngọngọ hardness maka njirimara zuru oke nke uru ya na-egosi.
Ihe nleba anya microhardness na-etinye ibu na ọrụ nnwale ahụ dị ka nke dị nro na edo dị ka o kwere mee, na-enweghị mmetụta na ịma jijiji.Iji hụ na izi ezi nke nsonaazụ ule ahụ, ọ na-adịkarị mkpa iji tụọ ọtụtụ ugboro n'akụkụ dị iche iche, wee chọta nkezi uru iji gosipụta uru siri ike nke oyi akwa ule permeability ma ọ bụ oge alloy.Maka oyi akwa infiltration a na-eji na oke okpomọkụ, enwere ike tụọ ike ya site na iji ihe nyocha microhardness dị elu.
