Makhalidwe ndi kugwiritsa ntchito Rockwell hardness tester

Mayeso a Rockwell hardness tester ndi imodzi mwa njira zitatu zomwe zimagwiritsidwa ntchito poyesa kuuma.

Zodziwika bwino ndi izi:

1) Rockwell hardness tester ndiyosavuta kugwiritsa ntchito kuposa Brinell ndi Vickers hardness tester, imatha kuwerengedwa mwachindunji, kubweretsa magwiridwe antchito apamwamba.

2) Poyerekeza ndi mayeso a kuuma kwa Brinell, indentation ndi yaying'ono kuposa ya Brinell hardness tester, kotero ilibe kuwononga pamwamba pa workpiece, yomwe ili yoyenera kudziwika kwa zida zomaliza za zida zodulira, nkhungu, zida zoyezera. , zida, etc.

3) Chifukwa cha mphamvu yodziwikiratu ya Rockwell hardness tester, chikoka cha kusakhazikika kwapang'ono pamtengo wowuma ndi wocheperako kuposa Brinell ndi Vickers, ndipo ndichoyenera kupanga misa yamakina ndi zitsulo zopangira matenthedwe ndi theka- kuwunika kwazinthu zomaliza kapena zomaliza.

4) Ili ndi katundu wocheperako wa Rockwell hardness tester poyesa, angagwiritsidwe ntchito kuyesa kuuma kwa wosanjikiza wosanjikiza pamwamba kapena wosanjikiza pamwamba.
