\u3010Features<\/strong>\u3011<\/div>\n
\u00a0<\/div>\n
PAS applies electrical energy directly to the powder, and uses both activation by discharge and thermal diffusion and electric field diffusion by energization, so it has many features that cannot be obtained with conventional sintering methods.<\/div>\n
\u00a0<\/div>\n
\u30fbRapid heating at 1,000 to 2,000 degrees Celsius per minute enables short-time sintering of high-melting point materials such as tungsten and molybdenum, laminated bonding of materials with different melting points, and sintering of functionally graded materials and superelectric materials.<\/span><\/span> <\/span><\/div>\n
– Non-metals such as fine ceramics can also be sintered.<\/span><\/span> <\/span><\/div>\n
\u30fbSince the sintered part is cleaned and activated by plasma discharge generated between particles, high vacuum or reducing atmosphere is not required.<\/span><\/span><\/span><\/div>\n
– Efficiently supplies high-density energy to the required locations and achieves sintering at a lower temperature than other methods.<\/span><\/span> <\/span><\/div>\n
– Because the sintering is done at a low temperature and for a short time, the crystals in the sintered body do not grow and the amorphous state remains almost unchanged.<\/span><\/span> – Powder particles are bonded together when energized, resulting in a material with excellent electrical and magnetic properties.<\/span><\/span> <\/span><\/div>\n
\u30fbBy achieving fine control of input energy, it is possible to sinter stacked materials with different melting points, functionally graded materials, and superconductor materials.<\/span><\/span><\/span><\/div>\n
– High-speed heating of 1,000 to 2,000\u00b0C per minute is possible, so sintering of high-melting point materials such as carbides, pyrotechnics, tungsten, and molybdenum takes only a short time.<\/span><\/span> <\/span><\/div>\n
\u30fbWithout the need for powder metallurgy know-how, anyone can easily obtain high-quality sintered bodies by looking at the sintering function, even those with no sintering experience or even those who are sintering powder for the first time.<\/span><\/span> Masu.<\/span><\/span> <\/span><\/div>\n
\u30fbIt is possible to sinter powders, beryllium, aluminum, titanium, molybdenum, etc., which are difficult to sinter using conventional sintering methods.<\/span><\/span> <\/span><\/div>\n
– Non-metallic materials such as cemented carbide, carbon, and fine ceramic materials that require time to sinter can be easily sintered.<\/span><\/span><\/span><\/div>\n
\u00a0<\/div>\n
\u3010Principle of discharge sintering\u3011<\/span><\/span><\/span><\/strong><\/div>\n
When a pulse voltage is applied directly to powder, micro discharges occur between the powder particles, generating plasma.<\/span><\/span> This impact evaporates impurities such as oxide films and adsorbed gases on the particle surface.<\/span><\/span> At the same time, heat and strain energy is accumulated on the particle surface and activated, and then a special power source generates Joule heat at the contact area between the activated particles, causing thermal diffusion.<\/span><\/span> <\/span><\/div>\n
At this time, electric field diffusion occurs in parallel due to the voltage, making it possible to sinter in a short time of several tens of seconds or even minutes.<\/span><\/span><\/span><\/div>\n
