Icyuma kitagira umuyonganagritni ubwoko bubiri bwitangazamakuru bwamenyekanye cyane.Ibicuruzwa bikora kimwe naicyumahamwe nicyuma, icyakora, bikozwe mubyuma.Harimo kwibumbira hamwe kwa nikel na chromium.Nibintu byiza byo gusuzuma mugihe umwanda wanduye wakazi udashobora kwihanganira.Ibicuruzwa byombi nibicuruzwa kandi rimwe na rimwe byerekanwa nka Shira Icyuma Cyuma no Gutera Icyuma Grit.

Ikirahure kitagira umuyonga ni serefegitura.Icyuma kitagira umuyonga grit ntigisanzwe kandi ni inguni.Kurasa ibyuma bizatanga ubuso bworoshye kuruta ibyuma bya grit.Ibyuma bya grit, ukurikije imiterere yabyo, bizahita, cyangwa byangirika hejuru.Nubwo isasu ridafite ingese ntirishobora kumenyekana muburyo bwo kurasa nkigitangazamakuru cyemewe cyo kurasa.

Byombi ibyuma bitagira umuyonga hamwe nicyuma kitagira ibyuma biza muburyo bukomeye nubunini.Ubwinshi bwinshi muri buri hejuru cyane kandi bugomba kwitabwaho bijyanye no gukoresha ibikoresho.Ibikoresho bikwiye bigomba gutoranywa kugirango bitange kimwe muri ibyo bicuruzwa.

Ibicuruzwa byangizaIrashobora kugufasha kumenya niba ibyuma bitagira umuyonga cyangwa ibyuma bitagira umwanda bishobora kuba igisubizo cyiza kubisasu byawe.Twishimiye guteza imbere inzira yawe muri laboratwari yiterambere ryimbere murugo.TwandikireUyu munsi.
