Gushyiramo icyuma cya karuboni n'icyuma gikozwe mu cyuma gikozwe mu buryo bwa alloy nkeya

1. Ibikoresho byo gutwika

 (1)Gushyiramo icyuma cya karuboni n'icyuma gikozwe mu cyuma gikozwe mu buryo bwa alloy low birimo gufunga byoroshye n'icyuma gikomeye. Gushyiramo icyuma gikoreshwa cyane mu gufunga byoroshye ni icyuma gikozwe mu cyuma. Ubushyuhe bw'iki cyuma bugera ku cyuma bwiyongera uko icyuma cyiyongera, bityo icyuma gikozwe mu cyuma gifite icyuma kinini kigomba gukoreshwa mu gufunga ingingo. Fesn2 intermetallic compound layer ishobora gukorwa ku murongo uri hagati ya tin n'icyuma muri tin lead solder. Kugira ngo hirindwe ko igikoresho kimeze muri uru rwego, ubushyuhe n'igihe cyo gufata bigomba kugenzurwa neza. Ingufu zo gufunga ingingo z'icyuma cya karuboni zikozwe mu cyuma gi ...

Mu gihe cyo gushushanya icyuma cya karuboni n'icyuma gito cya aloyi, umuringa woroshye, zinc y'umuringa n'ifeza, umuringa woroshye n'icyuma cya silver, zinc y'umuringa n'ifeza, ni byo bikoreshwa cyane cyane. Umuringa woroshye ufite aho ushongesha cyane kandi byoroshye gushonga icyuma cy'ibanze mu gihe cyo gushushanya. Ukoreshwa cyane cyane mu gushushanya icyuma gikingira gaze no gushushanya icyuma gikoresha vacuum. Ariko, ni ngombwa kumenya ko icyuho kiri hagati y'ingingo zikozwe muri brazing kigomba kuba kiri munsi ya 0.05mm kugira ngo hirindwe ikibazo cy'uko icyuho cy'ingingo kidashobora kuzuzwa bitewe n'uko umuringa utemba neza. Ibyuma bya karuboni n'ibyuma bikozwe muri brazing yoroshye bifite imbaraga nyinshi. Muri rusange, imbaraga zo gukata ni 150 ~ 215mpa, mu gihe imbaraga zo gukurura zikwirakwizwa hagati ya 170 ~ 340mpa.

Ugereranyije n'umuringa w'umwimerere, aho gushonga kwa zinc solder y'umuringa bigabanuka bitewe no kongeramo Zn. Kugira ngo hirindwe ko Zn iva mu gihe cyo gushonga, ku ruhande rumwe, ingano nto ya Si ishobora kongerwa kuri zinc solder y'umuringa; Ku rundi ruhande, hagomba gukoreshwa uburyo bwo gushyushya vuba, nko gushonga umuriro, gushonga induction na dip brazing. Impande z'icyuma cya karuboni n'icyuma gito cya alloy cyakozwe na zinc filler metal zifite imbaraga nziza kandi zitagira ubushyuhe. Urugero, imbaraga zo gukurura n'imbaraga zo gushonga z'ingingo z'icyuma cya karuboni zakozwe na b-cu62zn solder zigera kuri 420MPa na 290mpa. Aho gushonga kwa silver copper station solder ni hasi ugereranyije n'iya zinc solder y'umuringa, byoroshye gusudira urushinge. Iki cyuma gikwiye gushonga umuriro, gushonga induction na gushonga furnace steel ya karuboni n'icyuma gito cya alloy, ariko ingano ya Zn igomba kugabanuka uko bishoboka kose mu gihe cyo gushonga furnace, kandi umuvuduko wo gushyushya ugomba kwiyongera. Gushonga icyuma cya karuboni n'icyuma gito cya alloy hamwe na zinc filler metal bya feza bishobora kubona ingingo zifite imbaraga nziza kandi zitagira ubushyuhe. Amakuru yihariye agaragara mu mbonerahamwe ya 2.

(2) Guhindura: umwuka uhinduka cyangwa ukingira ugomba gukoreshwa mu gushushanya icyuma cya karuboni n'icyuma gito cya aloyi. Guhindura imiterere y'icyuma akenshi bigenwa n'uburyo bwatoranyijwe bwo gushushanya icyuma n'uburyo bwo gushushanya. Iyo hakoreshejwe icyuma gishongesha icyuma, amazi avanze ya zinc chloride na ammonium chloride ashobora gukoreshwa nk'amazi cyangwa andi mazi yihariye. Ibisigazwa by'iki gikoresho muri rusange birangiza cyane, kandi ingingo igomba gusukurwa neza nyuma yo gushushanya.

Mu gihe cyo gushushanya hakoreshejwe icyuma cyuzuyemo zinc muri copper, hagomba gutoranywa fb301 cyangwa fb302 flux, ni ukuvuga borax cyangwa uruvange rwa borax na aside boric; Mu gushushanya umuriro, uruvange rwa methyl borate na aside formic nabyo bishobora gukoreshwa nk'uruvange rw'amazi, aho umwuka wa B2O3 ugira uruhare mu gukuraho firime.

Iyo hakoreshejwe icyuma cya silver copper zinc brazing filler, hashobora gutoranywa fb102, fb103 na fb104 brazing fluxes, ni ukuvuga uruvange rwa borax, aside boric na fluoride zimwe na zimwe. Ibisigazwa by'iyi flux birangirika ku rugero runaka kandi bigomba gukurwaho nyuma yo brazing.

2. Ikoranabuhanga ryo gushushanya

Ubuso bugomba gusukurwa hakoreshejwe uburyo bwa mekanike cyangwa imiti kugira ngo icyuma cya okiside n'ibintu bikomoka ku bimera bivanweho burundu. Ubuso busukuwe ntibugomba kuba bukabije kandi ntibugomba gufatana n'udusimba tw'icyuma cyangwa indi myanda.

Ibyuma bya karuboni n'ibyuma bidafite aloyi nyinshi bishobora gushongeshwa hakoreshejwe uburyo butandukanye busanzwe bwo gushongeshwa. Mu gihe cyo gushongeshwa umuriro, umuriro utagira aho ubogamiye cyangwa ugabanya gato ugomba gukoreshwa. Mu gihe cyo gukora, gushyushya icyuma gishongeshwa umuriro no gushongeshwa umuriro bigomba kwirindwa uko bishoboka kose. Uburyo bwo gushyushya vuba nko gushongeshwa umuriro no gushongeshwa umuriro birakwiriye cyane mu gushongeshwa icyuma cyazimye kandi gishyushye. Muri icyo gihe, kuzimya cyangwa gushongeshwa umuriro ku bushyuhe buri munsi y’ubushyuhe bigomba gutoranywa kugira ngo icyuma cy’ibanze kidashongeshwa. Mu gihe cyo gushongeshwa icyuma gifite imbaraga nke mu kirere kirinda, si ngombwa ko umwuka uhagije gusa, ahubwo hagomba no gukoreshwa umwuka ushyushye kugira ngo icyuma cy’ibanze kinywe kandi gikwirakwizwe ku buso bw’icyuma cy’ibanze.

Ifu isigaye ishobora gukurwaho hakoreshejwe uburyo bwa chimique cyangwa mekanike. Ifu isigaye ishobora guhanagurwa cyangwa gusukurwa na lisansi, alcool, acetone n'ibindi bintu biyungurura ibinyabuzima; Ifu isigaye ishobora gukurwaho mu mazi nka zinc chloride na ammonium chloride mbere na mbere, hanyuma igasukurwa n'amazi ashyushye n'akonje; Ifu isigaye ya aside boric na aside boric biragoye kuyikuramo, kandi ishobora gukemurwa gusa hakoreshejwe uburyo bwa mekanike cyangwa kuyishyira mu mazi azamuka igihe kirekire.
