Ukuhlanzeka okuphezulu kanye nenani eliphansi Izinhlayiya zengxube yethusi yesiliva AgCu High-Entropy Alloys(HEA) Ngokwezifiso

I-soldering flux

Ama-alloys okushisela (ama-welding agents) Isiliva lisetshenziswa ngobuningi ukwenza ama-alloys okushisela, ikakhulukazi ama-alloys ama-ternary akhiwa isiliva, ithusi kanye nezinc. Ukwakheka kwesiliva kungaba kusuka ku-10 kuye ku-80%, ithusi kusuka ku-15 kuya ku-50%, kanye ne-zinc kusuka ku-5 kuya ku-40%. Iningi lalawa ma-alloys linamaphuzu ancibilikayo phakathi kuka-650 no-775C. Ngezinye izikhathi ithusi noma ithini yengezwa ukuze kwakhiwe ingxubevange enephuzu elincibilikayo eliphansi. Ama-alloy welding esiliva asetshenziswa embonini ukushisela lezo zinsimbi, okungukuthi, lapho ama-alloys e-brazing edinga izinga lokushisa eliphakeme lokushisela, angabangela ukukhula kwezinhlayiya ngokweqile noma eminye imiphumela eyingozi ensimbi ekushiseni.

Izinto zokuxhumana zikagesi

Ukumelana okuphansi kokuxhumana kwesiliva kanye nokuhamba okuphezulu kwenza kube insimbi edingekayo kakhulu emishinini yokuxhumana kagesi, kodwa uma i-voltage yokuxhumana iphezulu noma kune-arc, impilo ye-contactor eyenziwe ngesiliva ehlanzekile ayinde. Uchungechunge lwezinto ezakhiwe ngesiliva kanye nezinsimbi ezihlukahlukene ezingezona izinsimbi kanye ne-refractory ziye zathuthukiswa zaba amadivaysi okuxhumana kagesi anamandla amakhulu. Lezi zinto aziwona ama-alloys ngokwemvelo ngoba izingxenye azincibiliki zodwa. Zilungiswa ngobuchwepheshe be-metallurgical, okungukuthi, ngokucindezela nokufaka ingxube yempushana ecolekile yengxenye ngayinye. Izinto ezihlukaniswe ngesiliva ne-tungsten, isiliva kanye nokhiye, isiliva ne-nickel, isiliva negraphite, isiliva ne-oxidation picks, nesiliva ne-lead oxide zisetshenziswa njengezinto zokuxhumana zikagesi. Ukumelana kwazo ngokujwayelekile kuphakeme kancane kunokwesithelo esibuthuntu kodwa kuseduze nesiliva esincane esisebenzayo esinezinhlaka ezine ezifinyelela kuzo ngaphansi kokuqoshwa okuphuzi.
