I-Spherical Hafnium powder Manufacturing Additive

I-Hafnium powder(Hf) isetshenziswa njenge-blade ezindizeni ze-turbojet nasezinjinini zejethi ezisezingeni elibandayo. Ingase futhi isetshenziselwe ukwenza ama-valve, ama-nozzles nezinye izingxenye zokushisa okuphezulu.I-Hunan Huawei inikeza i-Hafnium Powder yekhwalithi ephezulu ngamanani okuncintisana.

I-Young's Modulus 78 GPa Spherical Hafnium Powder ingasetshenziswa emkhakheni we-powder metallurgy ukwenza ama-alloys anokumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, nezinye izakhiwo ezikhethekile. I-Heeger Materials inikeza i-Spherical Hafnium Powder yekhwalithi ephezulu ngentengo yokuncintisana. Isingeniso se-Spherical Hafnium Powder

Ukuhlanzeka okuphezulu, i-spherical degree ephezulu, izinhlayiya ezifanayo, izindawo zokusabalalisa eziwumngcingo, indawo enkulu ethize, umsebenzi ongaphezulu, ukwakheka kwe-spherical, ukuhlakazeka okuhle, izinga lokushisa eliphezulu le-oxidation, nokucwebezela. Ukumelana nokugqwala, kuncibilika ku-hydrofluoric acid namanzi asebukhosini, ekushiseni okuphezulu, kulula ukuncibilika ku-hydrofluoric acid futhi kwakha inkimbinkimbi ye-fluoride. Emazingeni okushisa aphezulu, i-hafnium ingaphinde ihlangane ngqo namagesi afana ne-oxygen ne-nitrogen ukuze yakhe ama-oxide nama-nitride ides.

Izicelo ze-Spherical Hafnium Powder

Isetshenziswa njenge-cathode yamashubhu e-X-ray, ama-alloys e-hafnium ne-tungsten noma i-molybdenum asetshenziswa njengama-electrodes kumashubhu okukhipha amandla aphezulu.

I-neutron absorber ekahle ingasebenza njengenduku yokulawula kanye nedivayisi yokuvikela ye-athomu futhi ingasebenza njenge-rocket propellant.

Ama-alloys e-Hafnium angasebenza njengongqimba olungaphambili lokuvikela lwe-rocket nozzle kanye nendiza egijimayo engena kabusha, futhi i-Hf-Ta alloy ingenza insimbi yamathuluzi nezinto ezivikelayo.

I-Hafnium powder isetshenziswa njengengxenye eyengeziwe kuma-alloys amelana nokushisa, njenge-tungsten, i-molybdenum, ne-hafnium tantalum.

Isetshenziswa njengesengezo samafutha we-hydraulic, ukuvimbela ukuguquguquka kwamafutha we-hydraulic ngesikhathi sokusebenza okunobungozi obukhulu, futhi kunemvelo eqinile yokulwa nokuguquguquka, nalesi sici, ngakho-ke ngokuvamile isetshenziselwa uwoyela we-hydraulic wezimboni. Amafutha e-hydraulic yezokwelapha.
