1) The metal elu nwere ike mfe ịghọta mirror mmetụta, Ra≤0.2μm.
2) Metal elu crystal remodeling, ọka nụchaa.
3) Microhardness dị elu mụbara site na 10% -30%.
4) Mwepụ nke ntụpọ kristal na nhazi nke nrụgide nrụgide na elu ígwè.
5) Ukwuu mma na-eyi nguzogide na corrosion iguzogide nke metal elu.
6) Na-abawanye ogologo ndụ nke akụkụ ahụ maka enyemaka nke ọrụ.
