Ụzọ maka ịnwale mgbaji siri ike nke ngwaọrụ carbide cimented site na Vickers hardness (eji Vickers hardness tester):
Ekwesịrị ịnwale ike nke carbide cimented n'ozuzu site na iji ọnụ ọgụgụ Rockwell hardness A. Mgbe ọkpụrụkpụ nke workpiece ma ọ bụ sample bụ ihe na-erughị 1.6 mm, Vickers ike usoro nwere ike iji maka ule. Yabụ kedu usoro maka ịnwale mgbaji siri ike nke ngwaọrụ carbide cimented?
Standardkpụrụ ule mgbaji siri ike na mgbaji siri ike ule usoro mmejuputa ụkpụrụ maka ihe ntọala carbide sirimented: JB/T 12616-2016;
Usoro nnwale bụ nke a:
Nke mbụ, mee ka a nwalee workpiece ka ọ bụrụ ihe nlele, wee kpochaa elu nke ihe nlele ahụ n'elu enyo, ma tinye ya n'okpuru microhardness tester iji mepụta ntinye n'elu a na-egbuke egbuke na conical diamond indenter nke ihe nleba anya siri ike, ya mere. na a na-emepụta mgbape ndị a na-emepụta ihe na akụkụ anọ nke ntinye.
