Ukukhethwa kokwelashwa kwesikhunta se-SMC

Ukuze kuthuthukiswe ukumelana nokugqokwa nokumelana nokugqwala kwendawo yesikhunta, kuvame ukuphathwa ngendlela efanele.
I-Chromium Plating ingenye yezindlela zokwelapha ezisetshenziswa kakhulu. Isendlalelo se-chromium Plating sinekhono eliqinile lokudlula emkhathini, singagcina ukucwebezela kwensimbi isikhathi eside, futhi akukho ukusabela kwamakhemikhali okwenzeka ezinhlobonhlobo zemithombo ye-asidi. Ubulukhuni bokumboza be-1000HV bulingana ne-HRC65, ngakho-ke inokumelana okuhle nokugqokwa. Isendlalelo se-chromium plating sinokumelana nokushisa okuphezulu, futhi ukubukeka kwayo nobulukhuni akukashintshi kakhulu lapho kushiswa ku-500 degrees emoyeni.
I-Nitriding inezinzuzo zokucubungula izinga lokushisa (ngokuvamile 550 ~ 570 degrees), ukuguqulwa kwesikhunta okuncane kakhulu kanye nokuqina okuphezulu kongqimba olungenayo (kufika ku-1000 ~ 1200HV, okulingana ne-HRC65 ~ 72), ngakho-ke ifaneleka kakhulu ukwelashwa kwendawo. imikhiqizo yepulasitiki ebunjiwe isikhunta. Izinsimbi eziqukethe izakhi ze-alloy ezifana ne-chromium, i-molybdenum, i-aluminium, i-vanadium, ne-titanium zinezakhiwo ezingcono ze-nitriding kunezinsimbi ze-carbon. Ukwelashwa kwe-nitriding uma kusetshenziswa njengezibunzi ze-SMC kungathuthukisa kakhulu ukumelana nokugqokwa.
