Gukoresha Ag

Amavuta ashingiye kuri feza nibindi byuma. Hariho ubwoko bwinshi bwa feza ivanze, icy'ingenzi muri byo ni: ifeza-umuringa, ifeza-magnesium ivanze, ifeza-nikel ivanze, ifeza-tungsten, ifeza-icyuma na silver-cerium.

Ibikoresho by'igiciro cyinshi hamwe na feza nkibice byingenzi. Mubisanzwe ukoreshe ifeza yera cyangwa ifeza yuzuye (99.9 *** hejuru) nkibikoresho fatizo, ugomba kwirinda bismuth, gurş, antimoni nibindi byangiza. Ifeza irashobora gukorwa hamwe nibintu byinshi mubisubizo bikomeye, ibice byuzuzanya cyangwa icyiciro giciriritse, kimwe nubwoko bwinshi bwibikoresho (ibinyoma). Ukurikije ibikenewe, birashobora gukorwa muri binary, ternary cyangwa polyalloys. Amavuta ya feza akoreshwa cyane mubice byinshi byikoranabuhanga mu nganda.

Ibyingenzi byingenzi bya feza ivanze ni:

. ifeza-nikel ivanze, ifeza-umuringa;

Harimo ifeza 90% na 10% y'umuringa bivanze bita ifeza y'ifaranga, gushonga ingingo 875 ℃; irimo 80% ya feza na 20% yumuringa wumuringa bita akazi keza ifeza, gushonga ingingo 814 ℃; irimo 40% cyangwa 60% ifeza n'umuringa, zinc, cadmium alloys bita kugurisha ifeza, aho gushonga birenga 600 ℃. Ahanini bikoreshwa muguhuza imbaraga zisabwa mubicuruzwa byicyuma.

.

. ifeza ya molybdenum, ifeza ya tungsten, ifeza ferroalloy, ifeza ya kadmium;

.

. ni Birenzeho Ibikoresho Byiza. Ifeza amalgam AgxHg, umweru utaringaniye ucagaguye bikomeye. Ibigize biratandukanye bitewe n'ubushyuhe bwo gukora; Ag13Hg (445 ° C), Ag11Hg (357 ° C), Ag4Hg (302 ° C), AgHg2 (munsi ya 300 ° C)

Ibikoresho bya silver bivanze biratera imbere.

Ifeza iroroshye cyane kandi yoroshye gukora. Mu rwego rwo kunoza imbaraga n’ubukomere no kongera imyambarire, kuva kera abantu bongereye umuringa kuri feza kugirango bakore ifeza-umuringa, ikoreshwa mu mitako, ibikoresho byo kumeza n’ibiceri bya feza. Kugirango tunoze imikorere ya silver-umuringa, akenshi ongeramo nikel, beryllium, vanadium, lithium nandi matsinda ya gatatu yibintu muri ternary alloys. Mubyongeyeho, hari ibindi bintu byinshi byongewe kuri silver bishobora no kugira uruhare mugukomeza.

Nubwo ifeza iba inert mu kirere kama, ariko biroroshye kuba sulferi irimo sulforo hamwe na sulfide. Gutezimbere ifeza ya sulfide irwanya kandi binyuze muburyo bwo kuvanga, nko kongeramo zahabu na palladium bishobora kugabanya umuvuduko wa firime sulfide. Byongeye kandi, ibintu byinshi byibanze byibanze nka manganese, antimoni, amabati, germanium, arsenic, gallium, indium, aluminium, zinc, nikel, vanadium muri feza nabyo birashobora kunoza imiterere yo kurwanya sulfure. Ibikoresho bishingiye kumashanyarazi bishingiye kumashanyarazi nubwoko bwinshi, hariho leta ya alloy, hanakoreshwa muburyo bwa powder metallurgie yakozwe muburyo butemewe, ikigamijwe ni ugushimangira, kutihanganira kwambara no kunoza imikoreshereze yumuriro.
