Indlela yokuhlonza uhlobo lweingxubevange yethusi?
Ithusi elimhlophe, ithusi, ithusi elibomvu (owaziwa nangokuthi “ithusi elibomvu”), nethusi (eliluhlaza okwesibhakabhaka-mpunga noma elimpunga-ophuzi) zihlukaniswa ngombala.Phakathi kwabo, ithusi elimhlophe nethusi kulula kakhulu ukuhlukanisa;ithusi elibomvu liyithusi elihlanzekile (ukungcola <1%) kanye nethusi (ezinye izingxenye ze-alloy cishe zi-5%), okunzima kancane ukuhlukanisa.Uma i-noxidized, umbala wethusi obomvu ukhanya kakhulu kunowethusi, futhi ithusi limnyama kancane noma liphuzi;ngemva kwe-oxidation, ithusi elibomvu liba mnyama, futhi ithusi li-turquoise (i-oxidation eyingozi yamanzi) noma ushokoledi.
Ukuhlukaniswa nezici zokushisela zama-alloys ethusi nethusi:
(1) Ithusi elihlanzekile: Ithusi elihlanzekile ngokuvamile libizwa ngokuthi ithusi elibomvu.Ine-conductivity kagesi enhle, i-thermal conductivity kanye nokumelana nokugqwala.Ithusi elihlanzekile limelelwa uhlamvu + T}} (ithusi), njenge-Tl, T2, T3, njll. Okuqukethwe kwe-oksijini kuphansi kakhulu, futhi ithusi elihlanzekile elingenalo ngaphezu kuka-0.01% libizwa ngethusi elingenawo umoya-mpilo, elimelelwa yi-TU (ithusi elingenayo), njenge-TU1, TU2, njll.
(2) Ithusi: Ingxube yethusi enezinki njengoba i-alloying eyinhloko ibizwa ngokuthi ithusi.Ithusi isebenzisa okuthi +H;(ophuzi) kusho u-H80, H70, H68, njll.
(3) Ithusi: Ngaphambili, ingxube yethusi nethini yayibizwa ngokuthi ithusi, kodwa manje ama-alloys ethusi abizwa ngokuthi ithusi.Okuvame ukusetshenziswa i-tin bronze, i-aluminium bronze ne-min bronze.I-bronze imelwe ngu-“Q” (cyan).
Izici zokushisela zamaalloyi ethusi nawethusi yilezi: ① okunzima ukuhlanganisa futhi kulula ukuwohloka;② kulula ukukhiqiza imifantu eshisayo;③ kulula ukukhiqiza ama-pores
I-Copper ne-alloy welding ikakhulukazi isebenzisa i-welding yegesi, i-inert gas shielded welding, i-arc welding engaphansi, i-brazing nezinye izindlela.
Ama-alloys ethusi nawethusi ane-conductivity enhle yokushisa, ngakho-ke kufanele ngokuvamile ashiswe ngaphambi kokushisela, futhi amandla omugqa omkhulu kufanele asetshenziselwe ukushisela.I-hydrogen tungsten arc welding isebenzisa uxhumano oluhle lwe-DC.Ekushiseleni igesi, ilangabi elingathathi hlangothi noma ilangabi elibuthakathaka le-carbonization lisetshenziselwa ithusi, futhi ilangabi le-oxidizing elibuthakathaka lisetshenziselwa ithusi ukuvimbela ukuhwamuka kwe-zinc.
