2. Nchara siri ike nke elu
Na mmepụta mmepụta ihe, mgbe ụfọdụ a na-achọ isi ihe na-arụ ọrụ ka ọ nwee ike ịdị mma nke ọma, ebe a na-achọkwa elu elu ka ọ bụrụ ihe siri ike ma na-eyi nguzogide.N'okwu a, a na-eji ikpo ọkụ dị elu, carburization kemịkalụ, nitriding, carbonitriding na usoro ndị ọzọ na-arụ ọrụ ọgwụgwọ elu n'elu workpiece.Ọkpụrụkpụ nke oyi akwa siri ike elu na-adịkarị n'etiti milimita ole na ole na milimita ole na ole.Maka ihe ndị nwere akwa akwa siri ike elu, enwere ike iji akpịrịkpa HRC nwale ike ha.Maka nchara nchara na-agbasi ike nke ọkara, enwere ike iji akpịrịkpa HRD ma ọ bụ HRA.Maka akwa akwa siri ike nke elu, elu Rockwell hardness scales HR15N, HR30N na HR45N kwesịrị iji.Maka elu dị gịrịgịrị nke siri ike, a ga-eji ihe nnwale micro Vickers hardness tester ma ọ bụ ultrasonic hardness tester.
3. Annealed ígwè, ígwè nkịtị, ígwè dị nro
A na-emepụta ọtụtụ ihe nchara n'ụdị annealed ma ọ bụ ahaziri nke ọma, na ụfọdụ efere igwe oyi na-atụ na-agbakwa akara dị ka ogo dị iche iche nke annealing si dị.Nnwale siri ike nke ígwè dị iche iche annealed na-ejikarị akpịrịkpa HRB eme ihe, mgbe ụfọdụ a na-ejikwa akpịrịkpa HRF mee efere dị nro na nke dị nro.Maka efere dị obere, a ga-eji ihe nleba anya Rockwell hardness testers HR15T, HR30T na HR45T.
4. Igwe anaghị agba nchara
A na-ebutekarị ihe igwe anaghị agba nchara na steeti ndị dị ka mgbakasị ahụ, nkwụsị, iwe ọkụ na ngwọta siri ike.Ụkpụrụ mba na-akọwapụta ụkpụrụ ekweghị ekwe nke elu na nke ala, na ule ike siri ike na-ejikarị Rockwell hardness tester HRC ma ọ bụ HRB.A ga-eji ọnụ ọgụgụ HRB maka austenitic na ferritic igwe anaghị agba nchara, HRC scale nke Rockwell hardness tester ga-eji maka martensite na mmiri ozuzo hardening igwe anaghị agba nchara, na HRN ọnụ ọgụgụ ma ọ bụ HRT nke Rockwell hardness tester ga-eji maka igwe anaghị agba nchara. tubes mgbidi na ihe mpempe akwụkwọ na ọkpụrụkpụ na-erughị 1 ~ 2mm.
5. Nchara akpara akpa
A na-ejikarị ule ike siri ike nke Brinell eme ihe maka nchara adịgboroja, n'ihi na microstructure nke nchara akparaghị ókè, na ntinye ule siri ike Brinell buru ibu.Ya mere, ule siri ike Brinell nwere ike igosipụta nsonaazụ zuru oke nke microstructure na njirimara nke akụkụ niile nke ihe.
6. Nkedo ígwè
A na-ejikarị ihe eji eme ihe nkedo na-enweghị usoro na ọka na-enweghị isi, yabụ a na-anabatakarị ule siri ike Brinell.Enwere ike iji ihe nleba anya Rockwell maka nnwale ike nke ụfọdụ ihe nkedo arụ ọrụ.Ebe enweghi ebe zuru oke na obere akụkụ nke ihe nkedo nke ọma maka Brinell hardness test, a na-ejikarị HRB ma ọ bụ HRC mee ihe iji nwalee ike, ma ọ ka mma iji HRE ma ọ bụ HRK, n'ihi na HRE. na HRK akpịrịkpa na-eji 3.175mm dayameta bọọlụ ígwè, nke nwere ike nweta mma nkezi ọgụgụ karịa 1.588mm dayameta bọọlụ ígwè.
Ihe nkedo siri ike nke nwere ike ịpụ apụ na-ejikarị Rockwell hardness tester HRC.Ọ bụrụ na ihe ahụ ezighi ezi, enwere ike tụọ ọtụtụ data ma were nkezi uru.
7. Carbide siri ike (hard alloy)
Nnwale ike siri ike nke ihe alloy siri ike na-ejikarị Rockwell hardness tester HRA.
