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 kuuma tester, kotero ilibe kuwononga pamwamba pa workpiece, yomwe ili yoyenera kwambiri pozindikira magawo omalizidwa a zida zodulira, nkhungu, zida zoyezera, zida, ndi zina.

3 ) Chifukwa cha mphamvu yodziwiratu ya Rockwell hardness tester , chikoka cha kusakhazikika pang'ono pamwamba pa mtengo wa kuuma ndi wocheperapo kuposa Brinell ndi Vickers, ndipo ndizoyenera kwambiri kupanga makina opangira zitsulo ndi zitsulo zopangira matenthedwe ndi kuyang'ana kwa mankhwala otsirizidwa.

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