Izimpushana ze-WC-CrC-Ni ezinokumelana nokugqokwa
Incazelo
Ulayini womkhiqizo we-WC-CrC-Ni oyimpushana uwuchungechunge lwezimpushana ezihlanganisiwe nezine-sintered ezinikeza enye indlela ye-chromium plating eqinile.Lezi zimpushana zenzelwe ukusetshenziswa ezindaweni eziphansi ze-asidi/i-alkali emazingeni okushisa afika ku-200 ℃, futhi zinikeza i-anti-oxidation enhle kakhulu kanye nokumelana nokugqoka emazingeni okushisa afinyelela ku-750 ℃.
Omunye wemikhiqizo eyinhloko kulo mugqa i-KF-66, equkethe u-23% CrC no-7% Ni, enobubanzi bezinhlayiyana ze-15-45 μm no-10-38 μm.Lo mkhiqizo uguquguquka kakhulu futhi ungasetshenziswa esikhundleni se-chromium plating ezinhlobonhlobo zezinhlelo zokusebenza.Isebenza kahle kakhulu ezindaweni eziphansi ze-acid/alkali emazingeni okushisa afika ku-200 ℃.Ngaphezu kwalokho, i-KF-66 inikeza ukumelana okuhle kakhulu kwe-oxidation futhi igqoke emazingeni okushisa afika ku-750 ℃.
Omunye umkhiqizo obalulekile ku-WC-CrC-Ni powder line yi-KF-66, equkethe i-43% CrC ne-14% Ni, enobubanzi obufanayo bezinhlayiyana ze-15-45 μm no-10-38 μm.Njenge-KF-66, le mpushana iyindlela enhle kakhulu yokufaka i-chromium plating eqinile, futhi isebenza kahle kakhulu ezindaweni eziphansi ze-acid/alkali emazingeni okushisa afika ku-200 ℃.
Ngaphezu kwe-anti-oxidation yabo ephakeme kanye nokumelana nokugqoka, ama-powders e-WC-CrC-Ni anikeza ezinye izinzuzo ezimbalwa ngaphezu kwe-chromium plating eqinile.Kokunye, kulula kakhulu ukuzisebenzisa futhi zidinga imishini ekhethekile.Ziyakwazi futhi ukuhambisana nemvelo, njengoba zingakhiqizi izinto ezinobuthi ezifanayo njenge-hard chromium plating.
Sekukonke, ulayini womkhiqizo oyimpuphu we-WC-CrC-Ni unikeza enye indlela esebenza ngempumelelo kune-plating ye-chromium eqinile yendabuko.Lezi zimpushana zinikeza i-anti-oxidation ephakeme kakhulu kanye nokumelana nokugqoka emazingeni okushisa aphezulu, okwenza kube ekahle ezinhlobonhlobo zezicelo zezimboni.Kungakhathaliseki ukuthi ufuna ukumiselela i-chromium eqinile noma udinga nje impushana esebenza kahle ukuze uyisebenzise ezindaweni ezinokhahlo, umugqa womkhiqizo we-WC-CrC-Ni uyisinqumo esihle kakhulu.
