Powdered metal sintering microwave
Web4 Nov 2014 · Almost all metals, including refractory metals (W, Re, Mo, etc), alloys, steels, have now been sintered successfully in 5-15 min. The selective heating feature of microwaves has led to effective brazing and joining of metal parts. Even bulk metals can be heated and melted in a microwave field and the melt can be cast into useful products. WebOther articles where microwave sintering is discussed: advanced ceramics: Rapid heating: …heating are plasma sintering and microwave sintering. Plasma sintering takes place in an ionized gas. Energetic ionized particles recombine and deposit large amounts of energy on the surfaces of the ceramic being sintered. Extremely high sintering rates have been …
