Cum materies ad contactum vacuum adhibita sint binaria et supra mixturam materiae, ac praecipua elementa habere debent notas falsi, pulveris metallurgiae et vacuum (atmosphaerae continentis) liquationis in productione et processu fabricando adoptantur.
Contactus electricae Infiltration method
Methodus infiltration communis est methodus refractoriae metallicae producendi et humile punctum metalli pseudoalloy liquefactum. Princeps liquefaciens punctum metallicum pre- sinteratum (vel pulveris sintered) premetur ad formam sceleti rari, et tunc humilis punctum metalli liquescens supra vel infra sceletum ponitur. Temperatura altior quam liquescens punctum metalli, liquefacit et infiltrat in osseum raritatem metalli ut hiatum impleat, ut opus densum obtineat.
Contactus electricae Mixta pulveris sintering
Pulvis permixtio processus sinteringis est processus productionis conventionalis pulveris metallurgiae, id est, pulveris mixtionis / prementis / sinteringis processus. In ceramicis producendis et carbide coagulo late usus est. Methodus metallurgica bene evoluta est. Secundum diversam temperiem sintering, in solidum-phasma sintering et liquido-sinteringi dividi potest.
Contactus electricae arcus vacuum remeling
In the slag free and low pressure environment or inert atmosphere, the consumable electrode melts rapidly under the high temperature of DC arc and re solidifies in the cold mold, so that the alloy can be refined in this high temperature melting process, so as to achieve the purpose of purifying, improving structure and improving performance.
