Ntabwo byanze bikunze hazaho igihombo mugukoresha ibyuma na grit, kandi hazabaho igihombo bitandukanye kubera uburyo bwo gukoresha nibintu bitandukanye byo gukoresha. Noneho uzi ko ubuzima bwa serivisi bwimyenda yicyuma butandukanye nabwo butandukanye?
Mubisanzwe, gukomera kwicyuma birongana umuvuduko wacyo wogusukura, ni ukuvuga gukomera kwicyuma, kwihuta kwihuta, bisobanura ko kwihuta kwicwa ryicyuma bizaba bigufi kandi ubuzima bwa serivisi buzaba bugufi.
Itara ryicyuma rifite ubukana butatu: p (45-51hrc), h (60-68hrc), l (50-55hrc). Dufata p hardness na h ubukana nk'urugero rwo kugereranya:
P Hardness muri rusange HRC45 ~ 51, gutunganya ibyuma bikomeye bisa, birashobora kongera gukomera kuri HRC57 ~ 62. Bafite uburemere bwiza, kandi burebure mubuzima burenze h.
H gukomera ni HRC60-68, ubu bwoko bwibyuma byarashe cyane, firigo iravunika cyane, ikonje cyane, byoroshye kumena, ubuzima bugufi, gusaba ntabwo ari byinshi. Cyane bikoreshwa ahantu bisaba kurasa hejuru.
Kubwibyo, benshi mubakiriya bagura amafuti hamwe na p hardness.
Dukurikije ikizamini, dusanga umubare wizunguruka wicyuma hamwe na p gukomera birenze ibya h bigoye, kandi p gukomera ni ibihe bikomeye bishobora kugera kuri 2600. Wigeze upima ibyumweru bingahe?
