Large particles (diskettes) were formed by applying a spark plasma sintering process to leached catalyst particles. Almost all of the catalyst specific surface area was retained after sintering. This may open a way to manufacture pellet type catalysts or electrodes with high specific surface area. [Pg.155]

Alternative processing methods also offer the potential to control the microstructure and final properties of nanocomposites. Both self-propagating high-temperature sintering and spark plasma sintering offer means to obtain metastable yet dense nanocomposites. Subsequent heat treatments can then be used to approach equilibrium microstructures, where the properties will be a function of the heat treatment temperature and time. In this way a variety of microstructures, and thus variations of the composite properties, can become available. [Pg.304]

Study on the Composition Graded Cemented Carbide/Steel by Spark Plasma Sintering... [Pg.361]

Lately, the spark plasma sintering has been used gradually in practical applications. The characteristics of this new sintering process are low- temperature and short- time sintering. The features of this process are expected to solve the above problems. Therefore, we tried to sinter- bond the composition graded cemented carbide powders on steel substrate by spark plasma sintering, and evaluated the structural and mechanical properties of this composite material. This paper reports the results of these evaluations. [Pg.362]

From the above results, it is confirmed that the Co composition graded cemented carbide/steel composite sinter- bonded by spark plasma sintering is sintered densely and also relieved of thermal stress. Therefore this composite material is expected to display the excellent properties as desired. [Pg.365]
