Tungsten Carbide VS HSS （1）

HSS (ngufi ku byuma byihuta) yari ibikoresho bisanzwe byo gukata ibyuma kera. Iyo tungsten karbide yaremye, yafatwaga nkuwasimbuye mu buryo butaziguye ibyuma byihuta cyane hamwe no gukomera, kwihanganira kwambara neza, no gukomera cyane. Carbide ya sima ikunze kugereranwa nicyuma cyihuta cyane bitewe nibisabwa bisa kandi bikomeye.

Imikorere ya tungsten karbide

Carbide ya Tungsten ni ifu ya micron nini yicyuma cya karbide igoye gushonga kandi ifite ubukana bwinshi. Binder ikozwe muri cobalt, molybdenum, nikel, nibindi. Yacumuye mubushyuhe bwinshi hamwe numuvuduko mwinshi. Tungsten karbide ifite ubushyuhe bwo hejuru bwa karbide kuruta ibyuma byihuta. Ifite HRC 75-80 kandi irwanya kwambara neza.

Ibyiza bya tungsten karbide

1. Ubukomezi butukura bwa tungsten karbide irashobora gushika kuri 800-1000 ° C.

2. Umuvuduko wo kugabanya karbide wikubye inshuro 4 kugeza kuri 7 z'icyuma cyihuta. Gukata neza ni byinshi.

3. Ubuzima bwa serivisi bwububiko, ibikoresho byo gupima, nibikoresho byo gukata bikozwe muri tungsten karbide bikubye inshuro 20 kugeza kuri 150 ibyo bikoresho bivanga ibyuma.

4. Carbide irashobora guca ibikoresho hamwe na 50 HRC.

Ibibi bya tungsten karbide

Ifite imbaraga nke zo kunama, gukomera guke, ubukana bwinshi, no kurwanya ingaruka nke.

Imikorere ya HSS

HSS nicyuma kinini cya karuboni nini cyane, nicyuma cyigikoresho gifite ubukana bwinshi, kwihanganira kwambara cyane, hamwe nubushyuhe bwo hejuru. Mugihe cyo kuzimya, ibyuma, chromium, tungsten igice, na karubone mubyuma byihuta bikora karbide ikomeye cyane, bikarwanya imyambarire yicyuma. Ibindi bice bya tungsten bishonga muri matrix, byongera ubukana butukura bwicyuma kugera kuri 650 ° C.

Inyungu za HSS

1. Gukomera kwiza, gukomera gukomeye, gukata gukabije.

2. Ubwiza buhoraho, busanzwe bukoreshwa mugukora ibikoresho bito bigoye.

Ibibi bya HSS

Gukomera, ubuzima bwa serivisi na HRC biri munsi cyane ya tungsten karbide. Ku bushyuhe bwo hejuru bwa 600 ° C cyangwa hejuru ya 600 ° C, ubukana bwibyuma byihuta bizagabanuka cyane kandi ntibishobora gukoreshwa.
