SINTERING Politechnika Krakowska

Sintering is the process by which metal powder compacts (or loose metal powders) are transformed into coherent solids at temperatures below their melting point During sintering, the powder particles are bonded together by diffusion and other atomic transport mechanisms, and the resulting somewhat porous body acquires a certain mechanical strength 6 SINTERING TABLE OF CONTENTS 61

Powder metallurgy – basics & applications

• Copper powder => Solution containing copper sulphate and sulphuric acid; crude copper as anode • Reaction: at anode: Cu > Cu + + e; at cathode: Cu + + e>Cu • Iron powder => anode is low carbon steel; cathode is stainless steel The iron powder deposits are subsequently pulverized by milling in hammer mill The

Safe carriage of Iron ore & other iron concentrates in bulk

the iron ore standard sampling procedure given in the IMSBC Code should be followed Precautions for carriage of iron ore: Iron concentrates concentrates of iron are produced by either: the dry method, in which high grade ore is crushed to remove waste material, leaving a low moisture content in the powdered ore Iron concentrates obtained by the dry method are susceptible to spontaneous combustion because of the air already trapped within the concentrate during the crushing process

Sintering in the Powder Metallurgy Process

In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow However, a common practice with ferrous PM materials is to make an addition of fine copper powder to
