Mmalite nke Vickers hardness tester
Vickers hardness bụ ọkọlọtọ maka ịnọchite anya isi ike ihe nke Robert L. Smith na George E. Sandland tụpụtara na 1921 na Vickers Ltd. Nke a bụ usoro nnwale siri ike ọzọ na-eso ụzọ Rockwell hardness na Brinell siri ike ule.
Ụkpụrụ nke Vickers hardness tester:
Vickers hardness tester na-eji ibu nke 49.03 ~ 980.7N pịa diamond conical square nwere akụkụ ikwu nke 136 Celsius n'ime ihe ahụ.Mgbe ejidechara ya maka oge a kapịrị ọnụ, a na-agbakọ uru ike ike Vickers site na ịlele ogologo diagonal nke indentation na iji usoro.
Ngwa ngwa ibu nke ụdị Vickers atọ ndị a (micro Vickers):
The Vickers hardness tester nwere ibu nke 49.03 ~ 980.7N kwesịrị ekwesị maka nha ike nke nnukwu workpieces na elu elu.
Obere ibu Vickers siri ike, nnwale nnwale <1.949.03N, dabara adaba maka nha ike nke obere workpieces, elu ngwaọrụ, ma ọ bụ mkpuchi;
Micro Vickers siri ike, nnwale nnwale <1.961N, dabara adaba maka nha ike nke foils metal na akwa elu dị oke mkpa.
Na mgbakwunye, nke ejiri akara Knoop, ọ nwere ike tụọ ike Knoop nke ihe ndị siri ike dị ka iko, seramiiki, agate, na nkume dị egwu.
Uru nke Vickers hardness tester:
1. The nha nso bụ obosara, si software ọla na superhard ọla, na ike achọpụtara, sitere na site a ole na ole ka puku atọ Vickers ike ụkpụrụ.
2. Indentation dị obere ma ọ dịghị emebi workpiece, nke a pụrụ iji maka ule siri ike na workpieces na-apụghị imebi n'elu nke workpiece.
3. N'ihi obere ule nnwale ya, ike nnwale kacha nta nwere ike iru 10g, nke nwere ike ịchọpụta ụfọdụ ndị dị gịrịgịrị na obere workpieces.
Ọdịmma nke Vickers hardness tester:
Tụnyere usoro nnwale siri ike nke Brinell na Rockwell, ule siri ike nke Vickers nwere ihe achọrọ maka ịdịrị elu elu nke workpiece.Ụfọdụ workpieces chọrọ polishing, nke na-ewe oge ma na-arụsi ọrụ ike
Vickers hardness testers bụ ndị ziri ezi na adịghị mma maka ojiji na ogbako ma ọ bụ na saịtị, na a na-ejikarị na laboratories.
