Isuzuma ry'ubukomere bw'icyuma gikingira n'ubukomere bw'ivunika Isuzuma ry'ubukomere bwa Vickers ry'igikoresho gikozwe muri karubide ikozwe muri sima

Ni ingenzi cyane gupima ubukana bw'agakoresho gakora ku cyuma gikingira. Agakoresho gagomba kugira ubukana runaka mu gihe cyo gukoresha kugira ngo imikorere yako ibe yizewe kandi irambe. Isosiyete ya Laihua ishobora guhindura uburyo butandukanye bwo gukanda budasanzwe hakurikijwe ibyo ikeneye, kandi ishobora gukoresha icyuma gipima ubukana cya Laihua mu gupima ubukana.
Igipimo cy’igerageza ry’ubukana bw’agakoresho ko gukingira muri rusange kivuga kuri ibi bikurikira:
1. Ubukana bwa Rockwell GB/T 230.1-2018
Iyi ngengabihe ikoresha uburyo bwo gupima ubukana bwa Rockwell n'igipimo cya HRC Rockwell cyo gupima ubukana, Ubu buryo bwo gupima bworoshye gukoresha kandi ni bwo buryo bwiza ku bakiriya.
2. Ubukana bwa Brinell GB/T231.1-2018.
Iyi ngengo y'imari ikoresha igipimo cya Brinell hardness HB mu gupima.
Igipimo ngenderwaho cy'isuzuma kivuga kuri:
GB/T 14370-2015 cyangwa JT/T 329-2010.
Bitewe n'imiterere y'agapira k'icyuma gafata icyuma, hakurikijwe ingano y'agapira k'icyuma n'ingano y'umurambararo w'icyuma, iyo uguze icyuma gipima ubukana, ni ngombwa guhindura ibikoresho by'umwuga nk'uko bikenewe kugira ngo hamenyekane neza agaciro kapimwe no kongera igihe cyo gukora icyuma gipima ubukana. Niba bibaye ngombwa, nyamuneka wohereze ingero zo gupimisha.
Uburyo bwo gupima ubukomere bw'ibikoresho bya karuboni bikozwe muri sima hakoreshejwe ubukomere bwa Vickers (koresha Vickers hard tester):
Ubukana bwa karubide ikozwe muri sima bugomba gupimwa hakoreshejwe igipimo cya Rockwell hardness A. Iyo ubunini bw'icyuma cyangwa icyitegererezo kiri munsi ya mm 1.6, uburyo bwa Vickers hardness bushobora gukoreshwa mu gupima. None se ni ubuhe buryo bwo gupima ubukana bwa karubide ikozwe muri sima?
Igipimo ngenderwaho cy’uburyo bwo gupima ubukana bw’ivunika n’uburyo bwo gupima ubukana bw’ivunika gikurikizwa ku bikoresho by’ibanze bya karubide ikozwe muri sima: JB/T 12616—2016;
Uburyo bwo gupima ni ubu bukurikira:
Ubwa mbere, kora igikoresho cyo gukoreraho ubushakashatsi kigomba gupimwamo icyitegererezo, hanyuma uhanagure ubuso bw'icyitegererezo mu buso bw'indorerwamo, hanyuma ugishyire munsi y'icyuma gipima ubukana bwa microhardness kugira ngo habeho icyuho ku buso busukuye ukoresheje diyama ifite ishusho y'icyuma gipima ubukana, kugira ngo imiyoboro yakozwe mbere igaragare ku mpande enye z'icyuma gipima ubukana.
Agaciro k'ubukomere bw'ivunika (KIC) kabarwa hashingiwe ku mutwaro wa indentation P n'uburebure bwa indentation crack extension C.
Uruganda rw’ibikoresho byo gupima rwa Laizhou Laihua ruhora ruhari kugira ngo rusubize ibibazo byose ufite.
